Product Introduction

The medical pass box is a straight-through static transfer chamber for moving packaged supplies and small clinical materials between adjacent controlled rooms without routine personnel passage. Its double-wall 316L stainless shell encloses the interlock components away from the cleanable chamber, while continuously joined internal surfaces and coved corners reduce ledges around the transfer path. Matching hinged doors on both sides use tempered-glass windows, compression gaskets and an electromagnetic interlock so only one side is released at a time. A simple front control switch and red-green indicators give operators an immediate local view of door status without adding an airflow or filtration module.

Key Features

An electromagnetic interlock holds the opposing door closed while one transfer side is open.

The 316L stainless interior uses smooth welded transitions and coved corners for accessible wipe-down cleaning.

Equal glazed windows let staff confirm chamber occupancy before operating either door.

A double-wall shell isolates lock hardware from the unobstructed transfer compartment.

Customer Product Concerns

Medical material transfer must limit unnecessary room entry while keeping the chamber observable, cleanable and unambiguous to operators on both sides.

Opening both sides together can create a direct path between rooms with different pressure or cleanliness conditions.The opposing electromagnetic locks allow one door to be released while retaining the other door closed.
Frequent disinfectant wiping can expose seams, ledges and mild materials to staining or residue accumulation.A 316L stainless chamber with continuous joints and coved internal transitions provides a corrosion-resistant accessible surface.
Staff may operate a hatch without knowing whether material remains inside or the opposite side is active.Matching observation windows and red-green status lamps provide visual confirmation before each transfer step.
Interlock parts projecting into the chamber create hard-to-reach cleaning points.The double-wall enclosure keeps the lock mechanism outside the unobstructed transfer compartment.

Typical Applications

Surgical-suite supply transferHospital pharmacy clean areasClinical laboratory support roomsCentral sterile service interfaces
