MICRODISCTM MEMBRANE FILTER
Filter Media Disc

Introduction
Micro-filtration is a size exclusion process where a contaminated fluid is passed through a microporous membrane or fibrous media
to separate micro-organisms and / or suspended particles from liquids or gases. The typical pore size used for micro-filtration
ranges from about 0.1 to 10 um.
Membrane Solutions offers a full offering of membrane materials and media for all types of liquids, solvents or gases, including PES, MCE, Nylon, PVDF , PTFE , PP, GF, CA , MCE, CN and PC Available disc diameters range from 13 mm to 293 mm (other custom
shapes also available), which are manufactured in a ISO 9001 certified facility. Most membranes can be sterilized and individually
packaged if required.

Filter Media DiscMCE Membrane Filter
Introduction
Membrane Solutions® mixed cellulose ester (MCE) membrane filters arecomposed of cellulose acetate and cellulose nitrate. Because MCE membrane isbiologically inert, it’s widely used in analytical and research applications, one of
the most widely used membranes in analytical and research applications. MCE
membrane filter is characterized by smoother and more uniform surface thanpure nitrocellulose filter. Also, the color contrast provided by the filter surface
facilitates particle detection and minimizes eye fatigue. MS also supplies sterile
gridded Membrane Filters with or without adsorbent pads.

Features and Benefits

Applications• High porosity• HPLC sample preparation• High protein binding can be blocked by pre-treatment or• Aqueous and solvent filtration

utilized in application• Sterile filtration or clarification of media and buffers• High purity: Triton-free• Bioassays• Sterile options available for critical applications• Clarification of aqueous solutions, particle removal and analysis,• Biologically inert with good thermal stability

CA Membrane Filter
Introduction
Membrane Solutions® CA Membrane Filters are composed of purecellulose acetate modified to offer researchers the lowest binding
filters available. Due to the extremely low binding characteristics,
these filters provide higher throughputs than competitive offerings
and reduce filter changes when filtering proteinaceous solutions.
CA membranes have pore size from 0.2um to 3.0um.

Features and Benefits

Applications• Lowest binding material available• Protein and enzyme filtration, sterilization• Hydrophilic• Biological fluid filtration sterilization• High throughput• Tissue culture media sterilization• Strength and dimensional stability• Diagnostic cytology• Uniform pore structure• Receptor binding studies

MICRODISCTM MEMBRANE FILTER
Filter Media DiscPP Depth Filter
Introduction
Membrane Solutions polypropylene (PP) microfiber filters are composed of pure polypropylene with 0.22 um & 0.45 um pore size
ratings. These filters offer broad chemical compatibility allowing its use with aqueous and organic solvent samples.
Polypropylene (PP) microfiber filters are the preferred filter media for pre-filtering HPLC samples where the detection levels are below
230 nm. The filters also exhibit negligible protein binding, which is essential for maximum sample recovery of critical, small volume
protein samples.

Features and Benefits• Hydrophobic• Highly porous membrane• Wide chemical compatibility• Low extractable levels• Custom cuts available

Applications• Aqueous and organic solvent filtration• Gas filtration

ChrompureTM Solid-phase
Extraction (SPE) Columns

ChrompureTM Solid-phase Extraction (SPE) Columns
Introduction
Solid-phase extraction (SPE) is a separation process by which compounds thatare dissolved or suspended in a liquid mixture are separated from othercompounds in the mixture according to their physical and chemical properties.
Analytical laboratories use solid phase extraction to concentrate and purify
samples for analysis. Solid phase extraction can be used to isolate analytes ofinterest from a wide variety of matrices, including urine, blood, water, beverages,
soil, and animal tissue. SPE can be classified in four types: reversed phase SPE,
normal phase SPE, ion exchange SPE, absorption SPE.
Membrane Solutions (MS) ChrompureTM SPE Columns are packed with a uniform distribution and density of high purity resins andsorbents, which ensures the reproducibility and consistency, so a reliable and efficient sample preparation process is guaranteed.

Guide to Select Membrane• High retention rate and recovery results in cost savings by maximizing each device.
• High quality materials and manufacturing provides confidence in batch-to-batch reproducibility• Optimized kinetics and flow characteristics for rapid sample preparations.
• With various packing, ensure better selectivity

Applications• Biological samples and natural compounds• Pharmaceuticals and drugs• Pesticides and antibiotics in food and agricultural matrices• Environmental Samples, organic compounds and pollutants.

MS® Chrompure SPE Columns Series
Membrane Solutions offers ChrompureTM silica-based, organic copolymer or inorganic chemical based SPE columns. The column
chemistries include C18, NH2, C8, Alumina, GCB, CN, Florisil, Si, SAX, SCX, PSA, PCX, PAX, etc. Column volumes are available in 1, 3
6 and 12 ml. Our design and manufacturing process minimize variability and improves recovery and cleanup procedures.

Hardware and Pumps

HARDWARE AND PUMPSIntroduction
Membrane Solutions (MS) SupervacTM Vacuum Pump has premium, corrosion-resistant wetted parts and is fitted with a patented multi-portvalve system that increases performance and tolerates liquids accidentally drawn into the system without loss of performance. It is acompact, lightweight, and easy to use pump. This vacuum pump combines all the advantages of lower pressure pumps with the perfectuniformity of diaphragm type operation. It compresses air by means of a long-life diaphragm, which ﬂexes within the compressor. The
fan-cooled, ball-bearing motor is permanently lubricated and has a single-use (fuse) overload protector. This pump is designed for small
volume/aqueous flask filtration applications, intended for ﬁltration of liquids or gases, or for other continuous or intermittent use, with all
types of ﬁlter holders.

Features and Benefits• Unit is light weight, easy to move and can work smoothly, which can guarantee the ideal vacuum and high rate of air flowing.
• It adopts the operation containing no friction, producing no calories and having no friction exhausts.
• The diaphragm is made of Nitrile Rubber, which resists the corrosion and has long operating life.
• Steady running, low noise and high operating efficiency

Application• Vacuum filtration• Vacuum distillation• Vacuum drying• On rotary evaporators• To extract and transfer gases

Transducer Filter

TRANSDUCER FILTER
Introduction
Membrane Solutions have been producing transducer protection filters for years and have the know-how to design a solution foryour application.
Protecting the transducer sensor from moisture and humidity from a patient’s breathing is a small but essential part in maintaining
the operational performance of the ventilator/anesthesia machine. It is also crucial in preventing cross-contamination between
patients.

Features and Benefits• Connections are available in female Luer lock inlet + male Luer slip outlet, double Luer lock,and stepped hose barb inlet + stepped hose barb outlet.
• Manufactured to ISO 9001:2015 and CE certified.
• Validated by Cytotoxicity <USP 87> and Biocompatibility <USP 88>,
which guarantees the safety of users.
• Varied filter membrane materials are available; PTFE is the most popular for Ventilator/Anesthesia
applications due to the natural hydrophobic properties of the membrane material.

Applications• Ventilator/Anesthesia systems.
• HST(Home Sleep Test) system cannula filters• PSG(Polysomnography) system filters.
• Transducer production in other medical devices.
