Smooth, Ultra-Clean Surfaces Eliminate Germ Traps, Simplify Cleaning and Disinfection
  • Smooth internal surfaces and rounded corners eliminate cracks and crevices that can harbor microbes
  • Lift-off windowed doors can be removed and cleaned, even autoclaved, for optimal germ control
  • Unique, durable, no-maintenance automated mechanical interlock is isolated from the pass-through chamber to eliminate microbial exposure
  • No-lip design simplifies material transfer by eliminating clearance restrictions
  • The chambers  are made of 316L stainless steel.
  • BioSeal™ edge seals against non-contaminating, non-outgassing, chemically resistant polyurethane inset into the door

BioSafe® Stainless Steel Pass-Through Chambers — Optimized for Aseptic Biological and Pharmaceutical Requirements

These unique Pass Throughs feature all-continuous-seam welds with radius corners to produce ultra-clean, smooth internal surfaces that wipe down quickly and easily. Their no-lip design eliminates clearance restrictions and gives you full use of the chamber interior. This design simplifies the transfer of materials into and out of the cleanroom or laboratory.

All components of these chambers have been engineered to optimize cleanliness and simplify disinfection. The doors feature inset polyurethane, a durable, chemically resistant, non-contaminating elastomer, which seals against the raised edge along the chamber perimeter. This bioseal eliminates the need for adhesive gaskets that can creep, crack and outgas.

Why is Electropolishing Critical?
Removes iron and other surface impurities that cause corrosion
Draws chromium and nickel to form a hard, protective finish
Removes irregularities (pits and burs) for an ultra-smooth surface that's easy to clean
More on Terra's electropolishing procedures...
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.

Unique Pass-Through Interlock Eliminates Cross-Contamination

The rugged automatic interlock mechanism prevents the handle and latch of either door from moving when the opposing door is open, protecting your cleanroom or laboratory from contamination during material transfer. By lifting the latch (to open the door),the interlock is automatically engaged; no additional manual handling is necessary. The rugged latch pins resist up to 200 pounds (90.7 kg) of force, ensuring that an interlocked door cannot be forced open.

The isolated interlock design further optimizes cleanliness. Because the mechanism is installed in its own, narrow-profile housing, the inside of the pass-through chamber remains unobstructed and easy to sterilize.

All models include two sets of stainless steel mounting brackets, which help support the chamber and frame the wall cut-out. Standard configuration is a mounting bracket welded 2"(51 mm) from the front of the chamber on the “clean” side; the remaining bracket is bolted to the wall on the “dirty” side and fits tightly against the chamber. This design accommodates walls of varying thicknesses and ensures minimal intrusion into valuable cleanroom space. Specify other desired bracket location when ordering.
