Automatic Mechanical Interlock

The mechanical interlock eliminates the chance of cross-contamination by ensuring that only one door at a time can open. This no-maintenance, all-stainless steel mechanism automatically engages the moment a door opens.

Stainless Steel Shield

The stainless steel shield protects the chamber floor from scratches and any other damage to the plastic surfaces.

Transparent Door

Transparent pass through doors with clear acrylic and static dissipative PVC options are offered in these ValuLine Pass Throughs. Compression latch and steel reinforcements provides stability to the pass-through door.

Dual Expansion Latches

Swell-type latches provide a firm grip via smooth compression that does not scrape any surfaces, particularly when compared to rotary latches. The rubber collar ensures a quiet closure that also dampens vibrations.

Stainless Steel Door Guard

A stainless steel stiffener reinforces the door's leading edge to provide a better seal and protect against damage. These bars also provide additional support to the door latches.

Flush Mounted Chamber

The pass-through chamber mounts flush against the cleanroom-side wall to minimize horizontal surfaces where particles can collect. The main body of the pass-through extends outside of the cleanroom.
