Terra Universal’s Smart Pass-Through Chamber redefines the capabilities of a pass through by solving a host of challenges that hospitals and labs face every daySmart® Pass-Through Chambers by Terra UniversalTerra Universal’s Smart Pass-Through Chamber redefines the capabilities of a pass through by solving a host of challenges that hospitals and labs face every day. When first introduced to the market, the pass through chamber had one-specific purpose: to reduce personnel traffic by providing a convenient means for sample transfer into and out of the cleanroom. With the Smart Pass Through, Terra has reimagined the jobs a pass through can perform by offering a menu of standard, add-on features compatible with every unit. These features are mounted external to the work area, so the integrity of the internal chamber is not impacted. Beyond sample transfer, the Smart Pass Through can disinfect products, log environmental conditions, track personnel or sample lots, streamline employee communication and add layers of security to your cleanroom.

Fire-Rated CleanMount® Pass-Through Chamber
Fire-rated pass-throughs protect personnel, equipment, and facility by maintaining the integrity of the fire-rated wall. They bear the UL 10B label for 90-minute fire exposure.
Durable Double Wall Construction
BioSafe double-wall construction triples unit lifespan and totally eliminates cleaning of accessories
Fire-Rated Pass-Through Glass Window
The wire-free glass-ceramic incorporate a surface-applied, fire-rated film and is impact rated for additional safety. These windows feature a high level of clarity and offer protection from either side.
Flush-Mount Design Prevents Dust Accumulation
CleanMount® pass-throughs hug the cleanroom wall, eliminating gaps that collect germs and particle and making them ideal for critical bio/pharmaceutical cleanroom use.
Lift-Off, Non-Shedding Door Hinges
Non-shedding, barrel-type door hinges allow the doors to lift off for thorough cleaning and decontamination (no tools required). Unlike industry standard continuous designs, these hinges comply with strict ISO levels.
High Caliber Hardware
Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.
Spring-Loaded Fire-Rated Passthrough Hinge
Spring-loaded hinges provide the self-closing capability required in a fire-rated wall. Automatic closing doors also simplify operation for operators with hands full.
Insulated Fire-Rated Pass-Through Door
Terra’s fire-rated door meets UL 10B requirements for 90-minute fire exposure, including hose-stream testing. The inside of the door is lined with 2"-thick SuperWool® Plus insulation to reduce heat transfer from elevated room temperatures.

Designed to be installed into any pass through. Install these racks within minutes with no special tools. Simply tighten a compression screw. Forgot to order racks before? No problem!
Prevent operator damage! A green light bar indicates the door is available for use, with the electronic interlock disengaged. The bar turns red when the opposing door is open to indicate the electronic interlock is engaged.
LED Recessed Light
Activates when either pass-through door opens; flush with the wall surface, covered by a static-dissipative PVC lens.
Adding a duct flange to the top of the passthrough allows the chamber to be ventilated by a remote blower. The ULPA-filtered inlet, housed in a perforated stainless steel cage, provides the necessary make-up air without contaminating the chamber.
Video Camera
Interior HD video camera records continuously or upon door-opening; can also be used for remote monitoring the transfer chamber.
Infrared beams detect objects placed inside the transfer chamber and connect to a remote alarm located up to 200 feet away from the pass through chamber. The crossed red lines depict the non-visible trigger lines between the IR transmitters and receivers.
Provides a timed cycle of 254 nm Ultra-Violet (UV) radiation to neutralize bacteria, viruses and mold spores within line-of-sight of the light fixture.
