## Background
CROSS-REFERENCE TO RELATED APPLICATION(S)
The present application claims priority from U.S. Provisional Patent Application No. 61/994,461, filed May 16, 2014, entitled “MANUFACTURING ARTICLE,” naming inventors Mitchell L. Snyder, Clemens E. Zoellner, and Thomas R. Nixon, and said provisional application is incorporated by reference herein in its entirety for all purposes.


FIELD OF THE DISCLOSURE
The present disclosure relates to a manufacturing article, and more particularly to a manufacturing article adapted for use in the production of biological or biologically active substances.
RELATED ART
Biological or biologically active substances are produced using equipment. Cell cultures are often grown and cultured for use in biological products. For example, cell cultures are frequently grown and cultured for use in biopharmaceutical processing. These cultures can be stored in vessels, where they can be exposed to varying processes and environmental conditions allowing for cellular growth and development.
Many traditional cell culture devices and techniques are developed for large scale production of cell cultures. These devices and techniques may utilize roller bottles or the like and can occupy large spaces. During small batch cell culturing or sampling processes, a single technician can be tasked with handling and transporting the cultures and associated equipment between various equipment and areas of a laboratory.
While relatively small compared to large scale productions, small batch production and sampling operations may include upwards of 80 liters or more of culture containing fluids. Traditional manufacturing articles are not readily adapted to handle small batch production or sampling operations as they are either large and bulky or too small and unstable to accommodate and sufficiently hold sufficient volumes of fluid.
There continues to exist a need for improved articles adapted for use with biological or biologically active substances, specifically, in both small batch operations and during large scape sampling processes.

DETAILED DESCRIPTION
The following description in combination with the figures is provided to assist in understanding the teachings disclosed herein. The following discussion will focus on specific implementations and embodiments of the teachings. This focus is provided to assist in describing the teachings and should not be interpreted as a limitation on the scope or applicability of the teachings. However, other embodiments can be used based on the teachings as disclosed in this application.
The terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a method, article, or apparatus that comprises a list of features is not necessarily limited only to those features but may include other features not expressly listed or inherent to such method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive-or and not to an exclusive-or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
Also, the use of “a” or “an” is employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one, at least one, or the singular as also including the plural, or vice versa, unless it is clear that it is meant otherwise. For example, when a single item is described herein, more than one item may be used in place of a single item. Similarly, where more than one item is described herein, a single item may be substituted for that more than one item.
As used herein, the term “substantially” refers to a deviation of less than 5% of the value as described in the whole state, such as less than 4% of the value as described in the whole state, or even less than 2% of the value as described in the whole state. For example, the phrase “substantially devoid” may refer to a characteristic that is at least 95% devoid, such as at least 96% devoid, or even at least 98% devoid of that characteristic.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The materials, methods, and examples are illustrative only and not intended to be limiting. To the extent not described herein, many details regarding specific materials and processing acts are conventional and may be found in textbooks and other sources within the biopharmaceutical processing arts.
A manufacturing article in accordance with one or more of the embodiments described herein can generally include a tray having a base defining a top surface and a manifold extending from the top surface of the base. In certain embodiments, the manifold can include a sidewall and an upper surface defining a channel. When viewed from the top surface of the base, the base can define an area, AB, and the upper surface of the manifold can define an area, AM. In accordance with one or more embodiments herein, AB can be greater than AM.
A manufacturing article in accordance with one or more of the embodiments described herein can generally include a tray having a recess adapted to receive a plurality of vessels and individually support at least one vessel of the plurality of vessels. In a certain aspect, this can reduce the weight and size of the tray while simultaneously affording at least one vessel independent support, thereby allowing a user to transport large volumes of fluid within the vessels.
Referring initially to FIG. 1, a manufacturing article in accordance with embodiments described herein can generally include a tray 100 having a base 102 and a manifold 104. The base 102 can define a top surface 106 and a bottom surface 108 separated by a thickness, TB. In a certain embodiment, the bottom surface 108 of the tray 100 can have a continuous, or nearly continuous, substantially flat surface spanning a length and width thereof. In another embodiment, the bottom surface 108 can be defined by a plane formed between or along portions of the tray that are adapted to contact, or rest against, a support surface, e.g., a table.
The manifold 104 can extend from the top surface 106 of the base 102, thereby defining a manifold sidewall 110 and an upper surface 112. In certain embodiments, the upper surface 112 of the manifold 104 can be parallel with the top surface 106 of the base 102. The manifold 104 can further define a channel 114 recessed from the upper surface 112 and extending toward the top surface 106 of the base 102. As discussed in greater detail below, the channel 114 can be adapted to receive at least a portion of a tube used to support and retain a fluid to and from a vessel disposed on the tray 100.
The manifold 104 can further define a plurality of sub-channels 118 recessed from the upper surface 112 and extending toward the top surface 106 of the base 102. Each sub-channel 118 can extend along a line that intersects the channel 114. In this regard, the channel 114 and sub-channels 118 can be in open communication. In particular embodiments, at least one of the sub-channels 118 can be oriented perpendicular to the channel 114. In yet more particular embodiments, all of the sub-channels can be oriented perpendicular to the channel 114. As discussed in greater detail below, each sub-channel can be adapted to receive at least a portion of a sub-tube used to transport a fluid to and from a vessel disposed on the tray 100.
As contemplated in particular embodiments disclosed herein, the tray 100 can at least partially comprise a polymer. Exemplary polymers can include, for example, a polyketone, a polyaramid, a polyimide, a polytherimide, a polyphenylene sulfide, a polyethersulfone, a polysulfone, a polypheylene sulfone, a polyamideimide, ultra high molecular weight polyethylene, a fluoropolymer, a polyamide, a polybenzimidazole, or any combination thereof. In a particular embodiment, the tray can comprise a high-density polyethelyne (HDPE).
Alternatively, and of particular significance during cell culturing, the tray 100 may be constructed at least partially from another material adapted to withstand temperatures of greater than 200° F., such as greater than 220° F., greater than 250° F., greater than 260° F., greater than 270° F., or even greater than 280° F., as the tray 100 may be subjected to these temperatures during processing and sampling. In this regard, a monolithic construction may increase resiliency by eliminating joints or other weakened locations that may deteriorate upon exposure to temperatures greater than 200° F.
In certain embodiments, an outer surface of the tray 100 can be generally smooth, for example, it is free from grooves, ripples, serrations, bumps, pitting, or any combination thereof. After reading this application, those skilled in the art will understand that surface roughness, such as caused during the normal manufacturing of the tray 100, constitutes “generally smooth” as used herein. In other embodiments, the outer surface of the tray can be smooth. The term “smooth” as used herein can generally refer to an enhanced surface finish, e.g., polished, buffed, etc. A smooth, or generally smooth, outer surface may reduce contaminant buildup along the outer surface of the tray, and in certain embodiments may increase sterility thereof.
In particular embodiments, an outer coating can be disposed along at least a portion of the outer surface of the tray. The outer coating can comprise a polymer, such as, for example, an elastomer. In particular embodiments, the outer coating can include an antimicrobial, antibacterial, or other contaminant reducing compound. The outer coating can have an outer surface that is smooth, or generally smooth, as discussed above in order to reduce contaminant building and increase sterility of the tray.
In a non-limiting embodiment, the tray 100 can be devoid, or substantially devoid, of right angled, or sharp, corners and edges. Rounded, chamfered, beveled, or even obtuse angles may instead be used along an outer surface of the tray to reduce buildup of contaminants and to reduce the likelihood that the tray can damage another component of the manufacturing article, e.g., a tube or sub-tube, during handling.
In particular embodiments, the tray 100 can be formed, for example, by injection molding, thermoforming, stamping, or otherwise shaped using any other similar known process or combination of processes for shaping. During the forming process, e.g., after completion of shaping, the tray may be sterilized to remove or destroy surface contamination. Exemplary sterilization techniques may include heat sterilization (e.g., steam sterilization, boiling water, dry heat), chemical sterilization (e.g., ethylene oxide, nitrogen dioxide, ozone, chlorine bleach, glutaraldehyde or formaldehyde, ortho-phthalaldehyde, hydrogen peroxide, peracetic acid, silver), radiation sterilization (e.g., ultraviolet light irradiation, ionizing radiation sterilization), or any combination thereof. In a preferred sterilization technique, sterility can be achieved using an autoclave for at least 15 minutes at 250° F. In such a manner, the tray may be essentially sterile, or sterile, in anticipation of usage. As used herein, “substantially sterile” refers to a sterility, e.g., a removal of transmissible agents such as fungi, bacteria, viruses, spore forms, etc., of no less than 90% as compared to an initial condition as measured prior to sterilization, while “sterile” refers to a sterility of no less than 99.9% as compared to an initial condition as measured prior to sterilization. After sterilization, the tray may be sealed or stored, e.g., in a sterile bag. This may reduce any recontamination of the tray.
As contemplated in a preferred embodiment herein, the tray 100 can be adapted for a single use. In this regard, a sealed tray 100 is utilized for no more than a single sampling or batch preparation process. After being used the tray 100 can be disposed. Alternatively, the tray 100 can be adapted for repeated use. In such a manner, the tray 100 may be subjected to resterilization between uses in an autoclave or other similar sterilization device.
In particular embodiments, the tray 100 can further include a handle 116 disposed along an outer surface thereof. In an embodiment, the handle 116 can be disposed along an outer surface of the manifold 104, e.g., the sidewall 110. In another embodiment, the handle 116 can be disposed along an outer surface of the base 102 (e.g., FIGS. 2 and 3).
In a preferred embodiment, the handle 116 may be monolithically formed with the tray 100. For example, the handle 116 may include a recess extending into the tray 100. In such a manner, the overall weight of the tray 100 can be reduced. In alternate embodiments (not illustrated), the handle can include a hook, a clasp, a projection, or any other similar extension from the tray. Moreover, the handle can be independently formed and attached to the tray by a fastener, e.g., a threaded fastener, or an adhesive. In this regard, a traditional handle, e.g., a knob or U-shaped handle, can be engaged with the tray.
In a preferred embodiment, the tray 100 can include a plurality of handles 116, such as, for example, two handles, three handles, four handles, or even five handles. The handles 116 can be disposed at desirable locations around the outer surface of the tray 100, such as, for example, at opposite ends of the manifold 104. For example, as illustrated in FIG. 2, a single handle 116 can be disposed on each opposite side of the base 102 at a position below the manifold 104. Alternatively, as illustrated in FIG. 3, two handles 116 can be disposed on each opposite side of the base 102 at positions equally spaced apart from a centerline (not illustrated) of the manifold 104. Additionally, a person of ordinary skill in the art will understand that, while the handles 116 can be disposed at any location along the tray 100, it may be desirable to symmetrically position the handles 116 across a centerline of the tray 100 to enhance balance and stability during transportation of the tray.
Referring now to FIG. 2, the manifold 104 can extend from the top surface 106 of the base 102 a distance, DM, as measured from the top surface 106 of the base 102 to the upper surface 112 of the manifold 104. In particular embodiments, DM can be greater than the thickness of the base, TB. For example, DM can be greater than 1.25 TB, such as greater than 1.5 TB, greater than 1.75 TB, greater than 2.0 TB, greater than 2.25 TB, greater than 2.50 TB, greater than 2.75 TB, or even greater than 3.0 TB. Moreover, DM can be less than 100 TB, such as less than 50 TB, less than 10 TB, less than 5 TB, or even less than 3 TB. In such a manner, DM can be within a range between and including 1.25 TB and 100 TB, such as within a range between and including 1.5 TB and 50 TB, within a range between and including 1.5 TB and 25 TB, within a range between and including 1.75 TB and 10 TB, within a range between and including 2.0 TB and 5 TB, or even within a range between and including 2.25 TB and 3.0 TB. Furthermore, DM can be within a range between and including any of the values described above. In a preferred embodiment, DM can be within a range of 1.0 TB and 3.0 TB, thereby allowing an upwardly extending manifold with a relatively low center of gravity. After reading this application, a person of ordinary skill in the art will recognize that in an alternate embodiment DM can be less than TB.
In particular embodiments, the sidewall 110 of the manifold 104 can be frustoconical. In such a manner, the sidewall 110 can taper from a wider bottom, coincident with the top surface 106 of the base 102, to a narrower dimension coincident with the upper surface 112 of the manifold 104. This can facilitate easier placement of a vessel along the base 102 of the tray 100 by providing an angled guiding surface which allows the vessel to be more easily placed in alignment with the base 102.
A reinforcement member 120 can be disposed along the sidewall 110 of the manifold 104 and may provide structural support thereto. In a further embodiment, the tray 100 can include a plurality of first reinforcement members 120 and a plurality of second reinforcement members 122. Each of the first reinforcement members 120 can have a height different than the height of the second reinforcement members 122. This may further enhance structural integrity of the tray 100 when transported by reducing torqueing forces and bending moments exhibited along the length and width of the tray 100. Specifically, as contemplated in particular embodiments herein, the reinforcement members 120 or 122 can assist in transmitting acute bending moments and torqueing loads exhibited along the base 102 into the manifold 104. This may allow transmission of loading conditions throughout the tray, resulting in a stiffer user feel.
As illustrated in FIG. 3, in yet more particular embodiments, the sidewall 110 of the manifold 104 can have at least two tiers 124 and 126. The tiers 124 and 126 can have any suitable stepped configuration adapted to correspond with a vessel (not illustrated) or to permit easier engagement of the vessel with the tray 100. Additionally, as discussed above, a tiered manifold can facilitate a stiffer base 102 by forming pleats which can spread torqueing and bending moments throughout the tray 100.
Referring now to FIG. 4, the upper surface 112 of the manifold 104 can define a surface area, AM, as calculated by a product of a length, LM, of the manifold and a width, WM of the manifold. The base 102 can define a surface, AB, as calculated by a product of the length, LB, of the base 102 and the width, WB, of the base 102, minus an area of any cutout portions, e.g., corner cutout portions 126.
In a particular embodiment, LM can be greater than WM, such as LM can be greater than 1.1 WM, greater than 1.2 WM, greater than 1.5 WM, greater than 1.75 WM, or even greater than 2.0 WM. In another embodiment, LM can be less than 5.0 WM, such as less than 4.0 WM, or even less than 3.0 WM. In particular embodiments, AB can be greater than AM. For example, AB can be within a range between and including 1.1 AM and 5.0 AM, 1.2 AM and 4.9 AM, 1.3 AM and 4.8 AM, 1.5 AM and 4.5 AM, 2.0 AM and 4.0 AM, or even within a range between and including 2.5 AM and 3.5 AM.
The channel can define an average width, WC, as measured along the upper surface 112 of the manifold 104. In a particular embodiment, WC can be less than WM, such as no greater than 0.99 WM, no greater than 0.75 WM, no greater than 0.5 WM, no greater than 0.25 WM, or even no greater than 0.1 WM. In another embodiment, WC can be no less than 0.01 WM, such as no less than 0.05 WM. Moreover, WC can be within a range between and including any of the values described above, such as, for example, between 0.15 WM and 0.30 WM. In certain embodiments the channel width, WC, can be constant along a length of the channel 114. In alternate embodiments, the channel width, WC, can vary as a function of location. For example, in a non-limiting embodiment, WC may be greatest at, or near, a center point of the channel. A non-constant width may facilitate greater security of the tubes within the channel 114.
In particular embodiments, the channel 114 can generally extend along the length, LM, of the manifold 104. In more particular embodiments, a centerline of the channel 114 can extend substantially parallel to the length of the manifold 104.
As illustrated in FIG. 4, the sub-channels 118 can each define a width, WSC. As illustrated in FIG. 4, in particular embodiments, WSC can be greater than WC. In such a manner, the sub-channels can permit a user to more easily maneuver sub-tubes (discussed in greater detail below) to respective vessels.
In other embodiments, WSC can be no greater than WC. In more particular embodiments, WSC can be less than WC. For example, WSC can be less than 0.99 WC, such as less than 0.9 WC, or even less than 0.75 WC. As described below, because the tubes in the sub-channels have proportionately less volumetric flow as compared to the tube in the channel, the dimensions of the sub-channel can be smaller than the dimensions of the channel. The combination of channels and sub-channels along the upper surface 112 of the manifold 104 can create a castellated upper surface 112 of the manifold 104.
Referring still to FIG. 4, in particular embodiments the tray 100 can further include at least one recess 128 adapted to receive at least one vessel (not illustrated). As illustrated in FIG. 5, the at least one recess 128 can be disposed on the base 102 of the tray 100 extending from the top surface 106 in a direction toward the bottom surface 108.
Referring now to FIG. 6, in a preferred embodiment, the tray 100 can include a recess 130 adapted to receive a plurality of vessels and individually support at least one vessel of the plurality of vessels. As used herein, “individually support” refers to a sidewall having sufficient lateral support, as measured in a direction parallel to the top surface 106 of the base 102, such that a vessel disposed within the recess is prevented from tipping, or rotating, about an axial length thereof, independent of whether a second vessel is disposed adjacent thereto. In other words, lateral support of a first vessel is not solely provided by a second vessel positioned directly adjacent to the first vessel.
In certain embodiments, the recess 130 can define a bottom wall 132 and a sidewall 134. When viewed from a top view, the sidewall 134 can define an undulating profile defining a maximum width, as measured between opposite sides of the recess 130, and a minimum width, as measured between opposite sides of the recess 130. In particular embodiments, the maximum width of the sidewall can be at least 1.1 times the minimum width of the sidewall, such as at least 1.25 times the minimum width of the sidewall, or even 1.75 times the maximum width of the sidewall.
The undulating sidewall 134 of the recess 130 can further define a plurality of discrete containment regions, e.g., a first discrete containment region 136, a second discrete containment region 138, a third discrete containment region 140, and a fourth discrete containment region 142. Adjacent discrete containment regions, e.g., 136 and 138, can be in open communication with each other and each adapted to receive one vessel.
The undulating sidewall 134 can be shaped and sized to accommodate vessels as necessary. For example, the first and second discrete containment regions 136 and 138 can house a first vessel and a second vessel, respectively. The first and second vessels can be aligned within the first and second discrete containment regions 136 and 138 such that a closest distance between the first and second vessels is no greater than 1 inch, such as no greater than 0.75 inches, no greater than 0.5 inches, or even no greater than 0.25 inches. In a further embodiment, adjacent discrete containment regions can be aligned such that the first and second vessels are in contact or immediately adjacent at a point location or along a plane.
In further embodiments, the tray 100 can include two recesses, the recess 130 and a recess 144. The recesses 130 and 144 can each be disposed on an opposite side of the manifold 104 along the base 102 of the tray 100. In certain embodiments, the recess 144 can be substantially identical to the recess 130, e.g., the recess 144 can define a maximum and minimum sidewall width equal to the maximum and minimum sidewall widths of the recess 130.
Referring again to FIG. 5, the recess(es) 130 or 144 can have a depth, DR, as measured from the top surface 106 of the base 102 in a direction perpendicular thereto. In the case the recess(es) have rounded or otherwise non-planar bottom walls, the depth, DR, of the recess(es) can be a maximum depth of the recess as measured from the top surface of the base to a bottom inner apex of the recess. In a particular embodiment, DR can be less than the thickness of the base, TB. For example, in specific embodiments, DR can be less than 0.99 TB, such as less than 0.95 TB, less than 0.90 TB, or even less than 0.75 TB. Moreover, in further embodiments, DR can be no less than 0.05 TB, such as no less than 0.1 TB, no less than 0.2 TB, or even no less than 0.25 TB. DR can also be within a range between and including any of the values described above. In a preferred embodiment, DR is between 0.75 TB and 0.99 TB, or more particularly, between 0.85 TB and 0.95 TB. In this preferred embodiment, the recess can provide lateral support to a vessel while maintaining structural rigidity.
The recess(es) 130 or 144 can further define a lip 146 extending around a periphery thereof and joining the sidewall 134 with the top surface 106 of the base 102. In particular embodiments, the lip 146 can be chamfered. This can facilitate easier insertion of a vessel into the recess and provide an insertion tolerance to a user.
Referring still to FIG. 5, the channel 114 of the tray 100 can have a depth, DC, as measured from the upper surface 112 of the manifold 104. In the case the channel 114 has a rounded or otherwise non-planar bottom wall, the depth, DC, can be a maximum depth of the channel as measured from the upper surface 112 of the manifold 104 to an inner bottom apex of the channel 114. In accordance with embodiments described herein, DC is less than DM. For example, DC can be no greater than 0.99 DM, such as no greater than 0.75 DM, no greater than 0.5 DM, no greater than 0.25 DM, or even no greater than 0.1 DM. In further embodiments, DC can be no less than 0.01 DM, or even no less than 0.05 DM. Moreover, DC can be within a range between and including any of the values described above. Of significance, DC need only be sufficiently large to at least partially receive a tube extending therethrough. In this regard, in a preferred embodiment, DC is no less than 0.25 times the diameter of the tube, such as no less than 0.5 times the diameter of the tube, or even no less than 0.75 times the diameter of the tube. Moreover, in a further embodiment, DC can be sufficiently large to receive the entire diameter of the tube.
Referring now to FIG. 7, the sub-channels 118 can each have a depth, DSC, as measured from the upper surface 112 of the manifold 104 in a direction toward the top surface 106 of the base 102, that is less than DC. In the case the sub-channels 118 have a rounded or otherwise non-planar bottom wall, the depth, DSC, can be a maximum depth of the sub-channels 118 as measured from the upper surface 112 of the manifold 104 to a bottom apex of the sub-channels 118. In particular embodiments, DSC can be equal to DC. In other embodiments, DC can be greater than DSC. For example, DC can be at least 1.01 DSC, such as at least 1.1 DSC, at least 1.2 DSC, at least 1.3 DSC, or even at least 1.5 DSC. In further embodiments, DC can be no greater than 10 DSC, such as no greater than 9 DSC, no greater than 8 DSC, no greater than 5 DSC, or even no greater than 2 DSC. Moreover, DSC can be within a range between and including any of the values described above. Of significance, DSC need only be sufficiently large to at least partially receive a sub-tube extending therethrough. In this regard, in a preferred embodiment, DSC is no less than 0.25 times the diameter of the sub-tube, such as no less than 0.5 times the diameter of the sub-tube, or even no less than 0.75 times the diameter of the sub-tube. Moreover, in a further embodiment, DSC can be sufficiently large to receive the entire diameter of the sub-tube.
Referring to FIG. 8, the tray 100 can receive and support at least one vessel 200 in the recess 130 thereof. In particular embodiments, at least a portion of the vessel 200 can be frustoconical. In further embodiments, at least a portion of the vessel 200 can be cylindrical. In yet further embodiments, when viewed from a top view, at least a portion of the vessel 200 can be polygonal, e.g., triangular, quadrilateral, pentagonal, hexagonal, heptagonal, octagonal, etc. This may increase vessel integrity and prevent collapse thereof.
In certain embodiments, the vessel 200 can comprise a polymer, such as an inert polymer adapted to contact a biopharmaceutical fluid. The vessel 200 may be translucent or opaque, such that a user can see a fluid contained therein. This may be particularly useful when the fluid must be visually inspected or volumetrically measured. In this regard, the vessel 200 can include indicia 202 along a side wall thereof. The indicia 202 can allow a user to quickly measure the volume of a fluid within the vessel 200. This can assist during mixing or process steps of production.
Moreover, in particular embodiments, the vessel 200 can comprise a material adapted to withstand, i.e., maintain operational functionality, at temperatures of greater than 200° F., such as greater than 220° F., greater than 250° F., greater than 260° F., greater than 270° F., or even greater than 280° F.
Varying sized vessels 200 can be utilized with the tray 100. For example, the vessel 200 can be adapted to contain at least 1 Liter (L) of fluid, such as at least 2 L of fluid, at least 3 L of fluid, at least 5 L of fluid, or even at least 10 L of fluid. Markings 204 can indicate to a user the volumetric capacity of the vessel 200.
A cap 206 can be installed on an opening of the vessel 200. In particular embodiments, the cap 206 can threadably engage with a complementary threaded portion disposed at the opening of the vessel 200. In alternate embodiments, the cap 206 can be clamped, snapped, adhered, mechanically deformed (e.g., pinched), bayonet connected, or attached to the opening of the vessel 200 by any similar process or combination thereof.
In certain embodiments, the vessel 200 can include an air port 208. The air port 208 can permit entrance of an ambient fluid, e.g., room air, into the vessel 200. This may permit pressure equalization within the vessel, allowing quicker filling and unfilling thereof. A filter can be disposed along each air port. The filter can prevent ingress of contaminants into the vessel.
