Improved Access Doors Reduce Wear, Enhance Performance
Dual side access doors in the plastic glove boxes 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. The all stainless steel model features an over-sized left-hand access door for convenient placement of larger equipment.
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 0.125" NPT pipe-tapped opening for connection of purge gas and a 0.25" 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 10"-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 in the Closed-Loop Filtration Glovebox, 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 0.125" NPT inlet and a 0.25" 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 self-balancing ionizing equipment for complete static safety, an externally mounted fluorescent light for enhanced viewing (which is already included on the polypropylene and stainless steel glove boxes), or an internally-mounted UV light.

Heated (Constant-Temperature) Filtration Glovebox
Terra's Heated Filtration Glovebox offers temperature control along with open-/closed-loop ULPA filtration, for a particle-free and constant-temperature environment. The push-button control panel on the motor housing is used to program temperature set-points up to 100°F (37.8°C), with accuracy of +/- 2°F/C.
Glovebox made of durable polycarbonate that is a thermal-resistant plastic and suitable for use in ISO-rated cleanrooms.
Control internal relative humidity with the optional Dual Purge™ system, designed to ensure constant positive pressure inside the glovebox with controlled nitrogen purges. Paired with the NitroWatch™ controller, these systems can be used to establish a specific set-point that is automatically maintained. Relief/Bleed valves (order separately) help to prevent over-pressurization that could damage the glovebox.
