Double-wall, insulated 304 stainless steel Smart Pass-Through™ chamber with refrigeration system maintains temperature to 5°C.
  • Refrigerated chamber shields materials easily damaged by warm/ambient temperatures
  • Refrigeration module can maintain temperature down to 5°C inside the chamber
  • Double-wall, insulated stainless steel chamber with static-dissipative PVC viewing windows
  • Mechanical door interlock automatically prevents cross-contamination
  • Ergonomic LiftLatch™ is comfortable to use, and creates a tight seal
  • Status Indicator Light quickly and easily confirms that the pass-through is operational

Don’t risk damaging sensitive materials and samples by exposing them to warm air. Terra’s Smart Refrigerated Pass-Through gives you peace of mind when transferring small items into a cleanroom, particularly if the material needs to stay inside the chamber for any length of time due to busy workflow.

Superior construction ensures protection on multiple levels. The pass-through incorporates a 1050 BTU closed-loop refrigeration module designed to maintain 5°C, or higher, inside the chamber. Additionally, continuous-seam welding produces a hermetically sealed enclosure that is easy to clean and sterilize, and reduces the introduction of contaminating particles. One piece gasketing mechanically adheres to the stainless steel door forming a close-fitting, uniform seal with no outgassing.

Firmlock™ is the maintenance-free 304 stainless steel interlock that automatically prevents both doors from being open simultaneously. This reduces air turbulence that introduces particles into the controlled environment. It also helps to maintain the internal constant temperature. The interlock has no power, gas, or other facility requirement, so it continues to operate when other systems shut down. It engages when the latch is lifted to open a door; additional manual handling is not necessary,

Viewing windows are made of static-dissipative PVC (SDPVC), preventing the build-up of electrostatic discharge: a magnet for contaminating particles! The surface is uniformly treated, so there are no “hot spots” to worry about. Treatment is also permanent; nothing will peel off over time, sacrificing the integrity of the pass-through. SDPVC has superior chemical resistance and flame-spread properties.

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.
