Product Introduction

This 12 x 12 x 12 in 304 stainless chamber minimizes the wall opening required for routine hand-carried transfers. A mechanical interlock prevents both doors from opening together without electrical controls or a fan system. The small cube is efficient for vials, instruments and compact packages, but load dimensions must allow clearance for the door and gasket on both sides.

Key Features

Minimal wall cutout

The compact chamber preserves partition area and suits crowded laboratory walls.

Utility-free interlocking

Mechanical sequencing operates without power, controls or filter service.

Cleanable stainless surfaces

304 stainless construction supports routine wipe-down between small transfers.

Applications

For specimen, instrument and small-part transfer through laboratory or cleanroom partitions where the load is already suitably wrapped. Confirm usable dimensions against the largest package, including hand clearance and shelf thickness if added.

Solutions for Your Application

A larger pass-through would consume scarce bench and wall space.Use the 12 in cube for a controlled list of small loads and prevent oversize items from being forced through.

A passive chamber will not recover airborne particles after each opening.Restrict use to compatible wrapped materials or select an actively filtered model when rapid cleanup is required.

Available Options

Choose door swing, shelf, flush trim, latch style and alternative stainless finish. Measure wall thickness and service-side access before fabrication.
