Product Details

Designed in the USA

• Dual-side access for passing RH-controlled materials through to another room

• Stable low-humidity storage conditions protect moisture-sensitive components

• Select optional NitroPlex™ for chamber-level RH control, or Dual Purge/NitroWatch systems for cabinet-level RH control

• Relief/Bleed (RB®) Valve included in each chamber prevents over-pressurization

• Mounting brackets included (one welded to "clean" side; the other attached to wall on opposing side)

• FirmLok mechanical interlock allows only one door at a time to open and operates without power, providing automatic protection against cross-contamination

• Allows contamination-free transfer of materials in and out of the cleanroom

• Reduces traffic in the cleanroom and eliminates excessive garbing

• Ideal for general cleanroom use and particulate control, using only non-shedding materials

• Stainless steel-framed doors, latches and hinges eliminate corrosion and extend service life

Pass-Through Basics

General Use Pass-Through Chamber

Don't risk operational delays or cleanroom shutdown because of a damaged door!
Terra's pass-through chambers last indefinitely, much longer than our standard product revision cycle. Pass-Through doors, however, are subject to damage, and ordering a legacy replacement can be costly and disrupt cleanroom operation. To avoid these problems, order replacements at the time you purchase the pass-through chamber; simply add “-RH” (for right-side hinge) or “-LH” (for left-side hinge) to the part number of the chamber.

Shutting the Door on Contamination
These Pass-Through Chambers cut down significantly on traffic and contamination by providing a better, safer way to transfer equipment and paperwork.

304 Stainless steel or powder-coated steel pass-throughs ensure clean operation. For especially stringent particle requirements, select an UltraClean™ electropolished 304 stainless steel pass-through.

Polypropylene and PVC models are suitable for chemical pass-through applications, and Static-Dissipative PVC models combine excellent chemical resistance with a surface resistivity of about 107ohms/square for enhanced static and particle control. Each model features viewing windows of a compatible material.

Doors on either side are outfitted with an automatic mechanical interlock that allows only one door at a time to open. The no-maintenance interlock has no power, gas, or other facility requirement, so it continues to operate when other systems shut down. It engages at the same time the latch is lifted to open the door; no additional hands-on manual steps are required.

Access Clearances 
Width = W (nominal) – 1.88”
Depth = D (nominal)* – 0.12”
Height = H (nominal) – 1.25”
* Subtract 0.5” for plastic chambers. Each door adds 0.5” to nominal depth.
Standard Pass-Through Mounting
All models include mounting brackets (stainless or powder-coated steel) and required hardware. Mounting brackets require 0.25” (6 mm) clearance between the wall cut-out and the pass-through. Standard mounting is 2” (51 mm) from the front of the cleanroom side (specify other desired location).
Wall Cut-Out = W (nominal) +0.5” x H (nominal) + 0.5”
Pass-Through Chamber Support Brackets
Order optional support brackets for wall-mount pass-through chambers that are 36"D or larger. They support the weight of the pass-through, and are designed to allow chambers to protrude 2" (51mm) on the cleanroom side. Indicate other desired position when ordering.

Stainless Steel Door Frame

Stainless steel-reinforced door frame with non-adhesive, "e-profile" gaskets ensures a long service life; shown on Series 400 Stainless Steel NitroPlex desiccator.

Ergonomic LiftLatches

Prevents hinge and door damage caused by the twisting and turning and applies uniform pressure to the non-adhesive door gasket; available with locking mechanism.

Automatic RB Valve

During normal operation, it allows a continuous low-level release of gas to maintain a positive pressure. It also functions as a check valve to ensure that air and contaminants cannot enter the enclosure in the event of a momentary negative pressure.

NitroPlex-Ready

Available NitroPlex Module automatically monitors and maintains low-RH set point to protect delicate samples while conserving nitrogen purge gas.

Stainless Steel Desiccator Racks and Shelving

All-stainless steel Series 400 Desiccators include stainless steel wire racks and a perforated pull-out shelf; order additional perforated or non-perforated shelves to suit storage requirements.

  • 3-inch Diameter Caster Set
    Casters are easily retrofitted for mobility. Products can be rolled out of the way when cleaning or relocated as workflow changes.
  • CleanTop™
    The CleanTop™ is designed for installations that require the chamber to be centered in the wall. The 30° sloping top on the cleanroom-side minimizes particle accumulation and accommodates laminar downward airflow.
  • Dual Purge and NitroWatch
    Terra’s Dual Purge and NitroWatch relative humidity controllers maintain a low-RH set-point inside a desiccator or glove box; they provide variable purge control that ensures continuous positive pressure and eliminates nitrogen waste.
  • Relative Humidity Temperature Data Logger
    Battery-powered RH/Temperature Data Logger measures and records internal desiccator environment at specified intervals; download to a PC to meet QA/QC or regulatory requirements.
  • Nitrogen Generator
    Terra’s Nitrogen Generators provide a continuous, reliable supply of clean, dry nitrogen up to 99% pure to eliminate dependence on bulky canisters to operate desiccators and glove boxes.
