Materials for
Every Requirement
Acrylic—
economical and ideal for general purpose processing.
Transparent
Static-Dissipative PVC— helps eliminate static charges
and the particles they attract
Nondissipative
PVC—is
ideal for operations with many corrosive chemicals
Polypropylene—
offers even greater chemical resistance (polypropylene glove boxes
feature a transparent Static-Dissipative
PVC viewing window).
Polycarbonate—
for operations that involve thermal stress.
One-piece
design with fused corners eliminates leaks
Specifications
Construction:
Solvent-welded
.5 "-thick clear acrylic or polycarbonate; chrome-plated hardware
Door
Openings:
10"
x 10" with gasketed doors, on both sides of chamber; doors
open inward.
Arm

Gas
Ports:
Tapped
.125" NPT inlet (for connecting flowmeter or Dual Purge™
System) and .125" NPT system pressure port; .25" NPT outlet
Note: A stainless steel work surface is recommended on all plastic glove
boxes to prevent scratching; this protection is especially important
with static-dissipative PVC.
Improved Access
Doors Reduce Wear, Enhance Performance
Dual side access
doors open inward to allow easy parts transfer from inside the chamber.
Doors feature stainless steel reinforcement frames that increase
the structural rigidity of the door by a factor of five. A built-in
LiftLatch securely seals the door without applying lateral torque
that could damage hinges.
All doors include
a unique, one-piece "e"-profile elastomer gasket that will not compress
or migrate over time. Its superb sealing capability saves nitrogen,
eliminates maintenance, and extends the service life of access doors—typically
the only component of a glove box that shows wear.
Nitrogen Controls
Ensure Low-Humidity, Contamination-Free Atmosphere
For optimal
processing conditions, select Terra's Glove Box Dual Purge™
System and NitroWatch®, which work in tandem to provide
completely automatic gas purging.
The Dual Purge™
System delivers a variable nitrogen purge into the glove box. During
normal operation, it provides a continuous low-Flow purge to maintain
a positive pressure that blocks out contaminants. In the event of
a sudden pressure drop, it activates a high-Flow purge to block
out contaminants and to quickly purge any moisture or contaminants
that do enter the chamber.
The NitroWatch® provides automatic low-humidity control. It monitors the internal
relative humidity and activates the high-Flow purge when the moisture
climbs above an adjustable set point. The Automatic RB® (Relief/Bleed) Valve provides safe pressure relief with these control
systems and also functions as a check valve, ensuring that no moisture
or contaminants enter the chamber in the event of a negative pressure.
All glove boxes feature a tapped .125"
NPT inlet and a .25"
NPT outlet for connection to these controls.
Select the
single or twin model; twin glove boxes feature two pairs of glove
ports to accommodate two operators (order gloves separately). Other
system options include a filter/blower module for filtering and
recirculating purge gas or purifying exhaust; self-balancing ionizing
equipment for complete static safety; and an externally mounted
fluorescent or UV illuminator for enhanced viewing (which is especially
important in the polypropylene glove box).
Note: These
glove boxes are not designed for use under vacuum. Select Terra's
Negative Pressure Glove Boxes for low-level vacuum applications
** Includes grounding terminals. The Stainless Steel Work Surface is required
with the Static-Dissipative PVC glove box to prevent scratching.
ete with .125" NPT inlet and .25" NPT outlet.
*** Includes 110VAC, 50/60Hz fluorescent illuminator (for 220VAC/50Hz,
add "-220" to the part number).
Air Locks Allow
Convenient Access
All
air locks include a .125"
NPT pipe-tapped opening for connection of purge gas and a .25"
NPT outlet to accommodate an Automatic RB® (Relief/Bleed)
Valve
For
applications involving large equipment, you can simply remove and
then reinstall the fully gasketed back wall. Dual 8" round arm ports
come equipped with flanges for easy connection to Terra's many gloves,
including the accordion-type glove assemblies.
Standard Air Lock
These air locks mount on the right side of the glove box to allow easy pass-through of parts into and out of the chamber. They feature a swing-down door on the front (outside) and a second door that is easy to open by a gloved hand from inside the glove box. One-piece nonadhesive gasket enhances sealing performance and extends service life. Capped ports are provided to allow purging of the air lock with nitrogen. Right mounting is standard.
Pass-Through Air Lock
Feature chrome-plated racks that accommodate adjustable shelves. Their in-line double-door construction lets you pass small parts easily into the glove box; you simply slide a shelf through the outside door to load parts and then through the inside door to unload them in the chamber. Order shelves separately. Right mounting is standard.
The Universal Air Lock features dual flanges (each with gaskets) to permit mounting on either the right or left side of any Terra plastic glove box. They also allow multiple glove boxes to be connected in series. Each air lock includes a capped .125" NPT inlet and .25" NPT outlet for connection to purge gas and Automatic RB® Valve. Select material compatible with your glove box(es). Right mounting is standard.
Stainless steel frames now standard on all access doors.

Bonded Sleeve and Glove Combination
For optimal economy and long-term durability, this combination features gloves that are permanently vulcanized to sleeves. The sleeves are made of heavy-duty, chemical-resistant neoprene and are designed for 8" port size. Hands are also made of sturdy neoprene; select desired size. Clamps included. 6" Port Size Available
Changeable Sleeve and Glove Combination
These accordion sleeves can be used with a variety of gloves, allowing you to change glove size or type without changing the sleeve itself. The convoluted section keeps the sleeve off the operator's arm for better air circulation and greater comfort. Supplied with one pair of nitrile industrial gloves (select desired size). Clamps included.
* Mounted horizontally on the inside rear wall, 3" from the bottom (specify other position, if desired). Includes master on/off switch, 15-Amp circuit breaker and 4 outlets.

Polypropylene Glove Box
No. 1681-29B
Stands for Series 100 Glove Boxes
Constructed of all-welded 1.5" square tubing, these stands are specially designed to support Series 100 glove boxes. Select powder-coated (white) steel or stainless steel stands, with or without hard rubber casters.
Double-wall polycarbonate and stainless steel glove boxes feature up to 4" of polyurethane insulation for energy efficiency at process temperatures between 120°F and -40°F. Call Terra to discuss your application!
Filtration Modules
These modules allow continuous recirculation of process gas through a HEPA or ULPA filter to remove particles, aerosols, microbes, chemical powders, and other fine contaminants. A variety of open/closed-loop configurations allow 100% exhaust, 100% recirculation, or a mixture of filtered and fresh make-up air.
Tilt-Up Viewing Window
Swings open for easy access. Dual piston mechanisms hold the window securely open. Price includes modification of Series 100 glove box to include hinged viewing window. Must be ordered tpgether with affected glovebox.
Allows Series 100 glove box to be lifted for easy placement over large equipment. Bottom attaches and seals to glove box by means of dual-gasketed latches located along the base.
