Pass-Through Autoclave

A double-door barrier steam sterilizer that transfers heat- and moisture-stable loads between separated cleanroom zones while maintaining controlled workflow.
  • Opposed interlocked doors support one-way material transfer
  • Barrier-wall sealing helps separate loading and unloading environments
  • Programmable vacuum-steam cycles provide monitored processing

Product Introduction

This pass-through autoclave is designed for pharmaceutical facilities, laboratories, and sterile-processing layouts requiring a defined dirty-to-clean workflow. Automatic vertical sliding or hinged doors reduce handling effort, while recipe controls coordinate conditioning, exposure, exhaust, and drying. Chamber dimensions, utilities, barrier trim, and unloading-side controls are adapted to the facility layout.

Key Features

Double-door pass-through pressure chamber

Mechanical and control-system door interlocks

Stainless barrier frame and sealed wall trim

Pre-vacuum, gravity, leak-test, and drying programs

Load-side touchscreen and unload-side status panel

Cycle data logging and alarm history

Automatic sliding-door option

Loading carts and transfer trolleys

Customer Product Concerns

Material transfer between cleanliness zones can undermine segregation if door logic, wall sealing, load flow, or cycle status is ambiguous. The system must also remove air reliably and prevent clean-side access to an incomplete or faulted load.

How is cross-zone access controlled?Independent door interlocks permit only the appropriate door to open according to cycle status and configured workflow.
How is the wall penetration sealed?A stainless barrier frame and custom trim interface with the partition to form a cleanable perimeter seal.
Can both sides see cycle status?The load side provides full control, while the unload side can display locked, cycle-complete, alarm, and door-ready states.
How are loads moved safely?Matched chamber racks, loading carts, and transfer trolleys support ergonomic and repeatable loading.

Typical Applications

Pharmaceutical component transferSterile manufacturing supportCleanroom garment processingLaboratory containment workflowsHealthcare sterile-processing departmentsBiotechnology production facilities

Technical Parameters

The pass-through autoclave integrates a jacketed stainless pressure vessel across a sealed partition. Independent load- and unload-side doors are interlocked so the clean-side door remains closed until a successful cycle is complete. Both sides receive appropriate status indication and operator controls.
