Terra's Series 100 Polymer Glove Boxes provide a clean, low-humidity environment for critical processing operations in such industries as semiconductor and pharmaceutical manufacturing. Their modular design lets you select the options you need for your application.

Materials for Every Requirement
Select from a variety of materials to suit your requirements. Economical acrylic is ideal for general purpose processing. Transparent Static-Dissipative PVC helps eliminate static charges and the particles they attract, keeping your glove box clean inside and out. Non-dissipative PVC is ideal for operations with many corrosive chemicals, and polypropylene offers even greater chemical resistance (polypropylene glove boxes feature a transparent Static-Dissipative PVC viewing window). Select polycarbonate for operations that involve thermal stress.

All glove boxes are fabricated to meet the most rigorous standards for cleanliness and durability. Solvent welding ensures a strong, non-contaminating structure. The 45° front slope allows the operator an uninterrupted overview of work in progress.

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.

Air Locks Allow Convenient Access
These glove boxes can be outfitted with air locks that maintain the integrity of the controlled environment without sacrificing convenience.

Standard and pass-through air locks mount on the right side of the chamber (left-mounting air locks are available on a custom basis). They minimize nitrogen loss and contamination inflow while parts are introduced or removed. Universal Air Locks extend system flexibility by mounting to either the right or left side of the chamber; their double flange design allows several chambers to be connected in series. 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 9 " round arm ports come equipped with flanges for easy connection to Terra's many gloves, including the accordion-type glove assemblies.

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
