2.0Description

Terra’s Series 100 Glove Boxes provide a clean, humiditycontrolled environment for a variety of critical assembly and 

inspection procedures. Their modular design allows for an 

assortment of options to suit your specific requirements. They are 

constructed of lightweight, transparent materials and feature all 

solvent-welded seams (with the exception of polypropylene, which 

uses fasteners) to ensure a tight seal that won’t outgas. 

Santoprene gaskets on the side doors and removable back panel 

provide a safe, positive-pressure seal while allowing full access to 

the internal chamber to insert or remove materials or equipment. 

The side doors open inward with ergonomic LiftLatches to allow 

an operator to pass materials in to and out of the glove box easily.

Series 100 Glove Box

© Copyright 2017 Terra Universal Inc. All rights reserved. • Revised Nov. 2019 • Document No. 1800-42

Terra Universal, Inc. • TerraUniversal.com • 800 S. Raymond Ave. • Fullerton, CA 92831 • TEL: (714) 578-6000 • FAX: (714) 578-6020 4

The Series 100 Glove Box maintains positive-pressure for a clean, low-humidity environment. It comes in five 

different materials and as a single or double model. Acrylic is suitable for general applications, but its staticgenerative properties and susceptibility to damage by a wide range of chemicals makes polyvinyl chloride, or PVC 

(either dissipative or non-dissipative), preferable in many cases. Polycarbonate is available for uses involving thermal 

stress. Polypropylene offers greater chemical resistance.

This glove box features two 1/8” pipe-tapped ports at the rear of the top surface, one for feeding in the purge gas and 

one for monitoring the internal cabinet pressure. These ports allow you to control the gas flow into the glove box.

You have the option of adding more options, described below, to enhance the control of the environment inside your 

Terra Series 100 Glove Box.

Flowmeter

For the administration of inert process gas into your glove box, a Flowmeter regulates the rate by which a process 

gas passes into the glove box. While generally installed with your order, a Flowmeter can be ordered as an 

aftermarket item and installed by the user, using Terra’s fitting kit no. 1600-56, which includes a brass male connector

(positioned at the Flowmeter inlet, directly behind the flow adjustment knob, for connection to the incoming gas line) 

and a hex nipple (which secures the Flowmeter to the “Gas In” port through the glove box wall).

It is recommended that customers requiring a Flowmeter also include Relief/Bleed (RB)® Valves, described below.

Automatic Relief/Bleed (RB) Valve

A necessity for any positive-pressure glove box installation, Terra’s Automatic Relief/Bleed Valve – or RB Valve –

ensures that the internal pressure of your glove box never reaches a level that could result in damage to the unit or 

injury to the user. This simple, elegantly-designed add-on automatically releases air from inside the glove box 

anytime the unit’s internal pressure exceeds the valve’s pre-set limit. 

Operation of a Series 100 Glove Box in a positive-pressure application without an installed RB Valve may 

result in damage to the unit and/or injury to its user(s). To prevent this from occurring, Terra installs 

multiple RB Valves in pressurized chambers. The quantity depends on the chamber size. CAUTION

Dual PurgeTM System

The Terra Dual Purge System 

assists the user by maintaining a 

positive-pressure environment 

inside a glove box while making 

efficient use of the user’s inert gas 

supply.

The Dual Purge System monitors 

the internal pressure of a glove box, 

feeding it a constant user-specified 

low-flow purge to maintain a 

positive-pressure environment that 

blocks out contaminants while 

economizing the gas supply. When 

the system detects a drop in 

pressure (such as when a door is Figure 2: NitroWatch/Dual Purge/Glove Box System Functional Diagram

Terra NitroWatch System

(Cat. No. 9500-00) 

opened), it automatically initiates a high-flow purge to help quickly return the system to a positive-pressure state while 

simultaneously flushing out any moisture or contaminants that might have entered the chamber. Once a positivepressure environment is regained, the system switches back to its low-flow operation.

Features of the Dual Purge System include a Flowmeter and pressure regulator to control the incoming flow of gas,

an internal positive pressure gauge to monitor the pressure inside the glove box, and a built-in pressure alarm, which 

provides audible and visible alarms when internal pressure falls below a user-defined point.

Dual Purge System w/ NitroWatch® or DewWatchTM Modules

Terra’s Dual Purge System can be upgraded with the purchase of a NitroWatch System or a DewWatch module for 

additional environmental control capabilities. While the Dual Purge System still allows a user to automatically 

maintain a positive-pressure environment inside their glove box, the NitroWatch module enables the Dual Purge to 

monitor relative humidity levels as well, using the system’s high-flow purging capabilities to flush out internal moisture 

until it reaches a user-specified sub-ambient RH level. The low-flow purge setting of the Dual Purge System then 

helps maintain the internal humidity levels, making efficient use of the gas supply. The DewWatch operates similarly 

to the NitroWatch but controls moisture by dew point.

Description (cont’d)

Both NitroWatch and DewWatch connect to the Dual Purge System via low-voltage cable, from which it both 

communicates with the Dual Purge System and draws its power; the NitroWatch and DewWatch require no external 

power connection.

Monitoring of the internal relative humidity is accomplished by a factory-installed sensor. This sensor can be 

calibrated by the user with the aid of a certified humidity measuring device.

NitroWatch and DewWatch feature 0-100% RH range with +/- 3% accuracy (at 60 degrees F), and an audible and 

visual alarm to notify users when humidity level increase above set threshold. No external power plugs are required.

Closed-Loop Filtration

Closed-loop filtration continuously draws air from the glove box to an externally-mounted filter to remove particulates, 

aerosols, spores, and other contaminants before directing the now-clean air back into the glove box. A four-position 

diverter valve gives the user the option of opening the filtration loop in order to draw in “fresh” air from outside the 

system.

Open-Loop Filtration

For applications where a clean environment is desired with little concern for humidity and pressure, in addition to the 

closed-loop (in-unit) filtration module detailed above, Terra also offers an open-loop filtration module. With an openloop filtration module, the components of the system reside outside of the glove box itself, maximizing the internal 

volume available to the user.

A HEPA intake filter ensures that the air entering the glove box is 99.99% free of contaminants 0.3 um or larger. A 

similar HEPA filter screens the exhaust air, removing any contaminants picked up inside the enclosure to ensure that 

the air exiting the system is safe for indoor release. Both filters are housed in disposable Plexiglas housings that 

facilitate safe handling and disposal when in need of replacing.

Internal-Mount (In-Unit) Filtration

This in-unit HEPA filtration module circulates the air inside a glove box through an enclosed HEPA filter, effectively 

removing 99.99% of particles 0.3 um or larger. This module can be used alone or in conjunction with the Dual Purge 

or Dual Purge with NitroWatch configurations.

IonBar Ionizing Bar

To neutralize the static charges of an enclosure, the Series 100 Glove Box has the option of coming installed with an 

ionizing bar.

Air Locks

Air Locks can be mounted on either side of the chamber to provide a safe, practical way of moving materials into and 

out of the work area. Materials are loaded into the air lock by means of an external door; an operator then opens an 

internal door inside the glove box to bring materials into the work area. Each air lock features its own gas inlet, and 

Automatic RB Valve port.

Glove/Sleeve Combinations

One piece glove/sleeve or two-piece combination glove/sleeve fit into the ports of Terra’s glove boxes and 

atmospheric chambers for safe, easy handling of materials and can be adapted to work with any number of 

compatible glove types. For a complete list of compatible gloves, visit www.TerraUniversal.com

Modular glove/sleeve combinations ship standard with one pair of tempered latex industrial gloves (select desired 

size). Attachment clamps are included.

Glove Port Covers

This optional feature allows you to seal the system and then remove gloves for cleaning or change-out – while 

maintaining the integrity of the internal glove box environment. The port covers can be removed from the glove box,

after use to maintain an uncluttered work environment.

Cord Port

This optional feature is built into the glove box at time of order, and provides a way for internal equipment to access 

electricity. Power cords are fed out of the hole in the lower rear panel, to nearby outlets.

Multi-Outlet Power Strip

Another way to make sure internal equipment has access to electricity is to install a multi-outlet power strip with on-off 

switch and surge protector. The cord for the power strip is fed out of the glove box through a small cord port, ready to 

plug into a nearby outlet.

4.0Operation

Glove Box Base Unit (without Flowmeter):

After setup, the Terra Series 100 Glove Box base unit operates without user intervention.

Glove Box Base Unit (with Flowmeter):

To increase or decrease the amount of gas entering your enclosure, turn the knob on the Flowmeter counterclockwise or clockwise as needed. Depending on the size of your glove box and the nature of its operation, a setting 

of 5-20 Standard Cubic Feet per Hour (SCFH) should suffice in providing a general positive-pressure environment 

(use 5-10 SCFH for two-arm port models, and 5-20 SCFH for four-arm port models).

Left on a very low setting, the fFowmeter will maintain a constant positive pressure that halts the influx of moisture 

through small cracks or through plastic walls (which are hygroscopic). However, this low flow rate will not block the 

influx of moisture or contaminants when a door is opened, nor will it quickly remove moisture once it enters the 

cabinet.

At a high flow rate, the system will remove moisture more effectively and block its influx when a door is opened, but 

the system will also consume an unnecessarily high amount of nitrogen at other times, and overpressures could in 

time damage seals or distort doors.

Operation of a Series 100 Glove Box in a positive-pressure application without an installed RB Valve may 

result in damage to the unit and/or injury to its user(s). To prevent this from occurring, Terra installs 

multiple RB Valves in pressurized chambers. The quantity depends on the chamber size. CAUTION

Glove Box with Filtration Module

After setup, the Terra Series 100 Glove Box with Filtration Module operates without user intervention.

Glove Box with Dual Purge System

After System Configuration, Terra’s Dual Purge System operates without user intervention. To adjust the system’s 

configuration after installation, refer to the System Configuration instructions in the section entitled “3.0 Installation –

Glove Box with Dual Purge System.” (DO NOT perform Initial Calibration if you have already successfully done so.) 

In addition to the System Configuration procedure, the Dual Purge System allows the user to monitor and change a 

limited number of parameters while in operation.

silence the alarm.

To activate the low-flow purge, turn the Flowmeter’s control knob counter-clockwise until the gauge reaches the 

desired setting. For most standard glove boxes, a flow-rate of 5-10 Standard Cubic Feet per Hour (SCFH) will 

maintain a positive pressure inside the glove box while making efficient use of your in-house gas supply.

• Use of low-flow purge is recommended if the glove box air lock will be opened frequently.

• Fine-tuning of the flow rate will limit how often the Dual Purge System’s high-flow bypass is activated.

• In the event of power outage, the high-purge flow will be disabled. The low-flow purge, however, will 

continue to operate to help maintain your glove box environment. 

• Typically, continual use of low-flow purge in an undisturbed chamber may, over time, result in a very 

low humidity level (<10% RH) inside the glove box chamber.

Use of Glove Box with Oversized Internal Equipment

Terra Series 100 Glove Boxes come standard with a removable back panel for the installation of equipment and 

devices that are too large to pass through the air lock. Equipment of this type includes scales, measures, and 

miscellaneous handling equipment.

To remove the back panel:

1. On the back panel, carefully remove each mounting screw (number varies with unit), dismounting the rear panel 

after the last one is removed.

2. Place your equipment inside the enclosure. As a general rule, your equipment should be clean and debris-free 

before inserting it into the enclosure.

3. If a cord port was installed in the back panel for electrical equipment, feed the power cords out of the hole prior 

to replacing the back panel.

4. Carefully align the screw holes of the rear panel with the holes on the glove box and reinsert the mounting 

screws. Carefully tighten the screws, ensuring an even seal along the gasket seal that lines the perimeter of the 

rear panel. Be carefully not to over-tighten the screws, as damage may result.

5.0Maintenance

Terra Series 100 Glove Boxes require minimal maintenance. They are designed to be versatile and yet simple to 

maintain. Occasionally, you may have the desire to clean the unit or replace its gloves. Instructions to do both are 

listed below.

Cleaning

Cleaning of the Terra Series 100 Glove Box can be accomplished by use of clean, lukewarm water and the option of 

a mild, non-abrasive detergent, applied with a clean, soft cloth. Take care to rinse the cleaning cloth thoroughly if 

granulated particles accumulate on it; avoid rubbing these particles into the enclosure’s interior surface.

If a cleaning detergent is used, rinse the enclosure with clean, lukewarm water and a clean, soft cloth prior to drying.

Dry the surface by blotting it gently with a clean, absorbent, low fiber-shedding cloth.

• DO NOT use abrasives or solvents on your Terra Series 100 glove box components. Use of such 

products can damage their visual appearance and/or transparency and might – especially in the case 

of acrylic – damage the performance and functionality of the product.

• DO NOT use solutions containing more than 5% bleach.

• DO NOT expose the Terra Series 100 Glove Box to extreme heat. Doing so will deform and damage 

the unit. (Static-dissipative PVC enclosures should not be exposed to temperatures above 80 degrees 

Fahrenheit.)

CAUTION

Installing/Removing Gloves

The Terra Series 100 Glove Box features a user-friendly method for glove replacement.

Items you will need:

- Slotted Screwdriver - Replacement gloves and/or sleeves, having 

the appropriate diameter for your glove ports.

Ensure that there is neutral pressure inside the Glove Box before attempting glove replacement.

WARNING

To Replace Whole-Molded Gloves:

1. Pull back the sleeve overlap on the glove port, exposing the screw cinch fastener securing the glove to the port.

2. Using a slotted screwdriver, loosen the cinch from around the port and remove it.

3. Remove the glove sleeve overlap from around the port.

4. Extract used glove from the glove box.

5. Insert new glove through the glove box port. Ensure that the proper hand is inserted into its corresponding 

port (left to left; right to right). Arrange the gloves so that they are properly aligned (right-side up) and at an 

ergonomic, user-friendly angle. A slightly-inward angle may be desirable, particularly for more rigid glove types.

6. Wrap the end of the glove sleeve (the last 2”-3” of sleeve) over the glove port, leaving enough sleeve material to 

overlap upon itself and cover the screw cinch. There should be no creases or wrinkles where the glove sleeve 

covers the glove port caused by an ill-fitting or poorly-aligned sleeve.

Maintenance (cont’d)

7. Replace the screw cinch, tightening it to create an airtight seal between the glove port and the glove sleeve.

8. Fold the rest of the glove overlap over the screw cinch to prevent unintentional tampering with the cinch and to 

provide a clean, safe finish to the glove port.

To Disassemble/Reassemble Modular Gloves:

The hand component of Terra’s glove assemblies can be modified with the sleeve component remaining mounted to 

the glove port or with the sleeve removed from the glove port. If you wish to remove the entire assembly before 

modifying it, follow Steps 1-4 in the section titled, “Section 5.0 – To Replace Whole-Molded Gloves.”

It is recommended that you remove the entire glove assembly before replacing one of its components, even 

if you are replacing only the glove component. This will facilitate ergonomic alignment much more easily 

than if the sleeve was to remain attached to the glove port. NOTE

The hand component of Terra’s glove assemblies is attached to its sleeve component by a special joining ring. This 

ring securely binds the ends of both components together, essentially sealing the assembly against leaks or 

contamination.

To disassemble the glove assembly:

1. Reaching into the glove assembly, locate the joining ring (a hard plastic cuff where the sleeve and glove meet) 

and pull it toward you, inverting the glove upon itself. Only invert the glove to a length required to comfortably 

access and work with the joining ring.

2. Remove the binding spring from the joining ring. This circular spring can be detached from itself (where one end 

meets the other) or rolled out of its setting with applied force. Set the spring aside for installation. The retaining 

ring can now be separated from the glove and sleeve components.

3. Remove the retaining ring from the glove and sleeve components. Set the ring aside for installation. The glove 

and sleeve are now separated.

4. If the sleeve is to be replaced, turn the new sleeve in upon itself as the old sleeve was during disassembly. This 

will ready the sleeve component for attachment to the glove component.

5. Insert the glove to be attached through the inverted opening of your sleeve. Align the edge of the glove sleeve 

with the edge of the glove hand.

6. Place the joining spring over the inside-out glove sleeve. Fold the glove sleeve over the outside of the joining 

ring, covering it completely.

7. Fold the end of the glove hand over the joining ring, so that it overlaps what you have already done with the 

glove sleeve.

8. Reattach the retaining spring so that it compresses the glove/sleeve ends overlapping the joining ring into the 

grove that runs along its outside diameter. The two parts are now securely joined.

9. Carefully push the retaining ring back into the glove sleeve until it has returned to its right-side-out configuration. 

Your reassembly is now complete.

Exercise care when pushing the joining ring back into the glove sleeve. As the assembly is extended, the 

diameter of the sleeve will narrow, increasing friction between the sleeve and the joining ring. Excessive 

friction between the two may dislodge the retaining spring, forcing a reassembly of the two components. CAUTION

10. If you removed the entire assembly from the glove port, reattach the assembly by following Steps 5-8 of the 

section titled, “Section 5.0 – To Replace Whole-Molded Gloves.”

6.0 Troubleshooting

This table describes the most common performance issues, their causes, and recommended courses of action.

Symptom Possible Cause(s) Solution

Power Concerns

All Accessories

System won’t turn 

on.

- Power cord not plugged in. - Inspect power cord leading from unit. Make sure that it is fully 

connected to the unit’s power port.

- Make sure that the power cord is plugged into a functioning outlet 

of appropriate voltage.

- Unit not switched ON. - Switch unit ON. 

- Power supply/outlet is faulty/damaged. - Try operating the unit from another outlet.

- Check your building’s fuse box, ensuring that the fuses governing 

your work area are not blown and are in good condition. Replace 

them if necessary.

Dual Purge

- Internal fuse is blown. - Using standard screwdriver, remove the housing of the Dual Purge 

system. A 1⁄2-amp fuse is mounted on the circuit board controller. 

If this fuse is blown, it needs to be replaced. Call Terra for a 

replacement fuse.

Pressure Concerns

Dual Purge

System stays in 

high-flow purge at 

all times.

...or...

System constantly 

switches between 

high- and low-flow 

purge.

- Improperly programmed system.

- System settings are too high.

- Inadequate Flowmeter setting.

- Disconnect the Dual Purge System from the glove box, internal gas 

supply and NitroWatch Module. Repeat INITIAL CALIBRATION, 

SYSTEM CONFIGURATION, and NITROWATCH 

CONFIGURATION processes as indicated in Section 3.0.

- Adjust the “Press” settings during SYSTEM CONFIGURATION. 

For most applications, the default setting of 20 milli-inches WG 

should suffice. Settings higher than 70 milli-inches WG may 

produce constant high-flow purge.

- Inadequate Flowmeter setting. - Increase Flowmeter setting to maintain positive-pressure purge 

during low-flow operation.

NitroWatch

- Low humidity settings. - Wait for the humidity levels to lower to your specified settings.

- Raise your desired humidity levels (See Section 4.0)

- If working with moisture-containing material, increase Flowmeter 

setting to allow for greater moisture-purging during low-flow 

operation.

Glove Box

- Glove box leak present. - Ensure that the doors to the enclosure are properly closed.

- Ensure that your glove sleeves are properly sealed against the 

glove ports.

- Inspect all gaskets and seals for misalignment, cracks or peeling. 

If the rear panel has been recently removed for equipment 

insertion, pay particular attention to this area.

- Contact Terra Universal for assistance.
