Cleanroom Pass-through cabinets
Cleanroom Pass-Through Cabinets: High-Volume Material Transfer Solutions
In large-scale pharmaceutical and biotechnology facilities, transferring bulk materials, heavy equipment, or high-volume consumables requires more than a small wall-hatch. Metrolabs provides high-accuracy Cleanroom Pass-Through Cabinets, engineered as floor-to-ceiling or mid-sized structural gateways that maintain the environmental integrity of your sterile suite while optimizing logistics.
Our cabinets are built with a “Zero-Ledge” philosophy, ensuring that your bulk transfer process remains as pristine as your most sensitive research.
Engineered for Scale and Sterility
Unlike standard pass boxes, Metrolabs Pass-Through Cabinets are designed to handle significant weight and volume while acting as a robust airlock.
Structural Integrity & Material Excellence
Constructed from heavy-gauge SS 304 or SS 316L, our cabinets are built for long-term performance. Reinforced Flooring: The base is engineered to withstand the impact of heavy containers or the wheels of a Cleanroom SS Trolley. Seam-Free Welding: All internal joints are TIG-welded and ground smooth to eliminate microbial harbor points and facilitate easy decontamination.
Hygienic Viewing and Accessibility
Flush-Mounted Windows: Toughened safety glass viewing panels are installed perfectly level with the stainless steel door surface, preventing dust accumulation on the edges. Full-Height Doors: Designed for ergonomic access, allowing staff to move materials in and out without unnecessary lifting or bending.
Advanced Interlocking Safety
To protect the pressure gradient of your facility, we utilize a sophisticated fail-safe system. Electromagnetic Interlocks: Prevents both the "clean side" and "dirty side" doors from being opened at once, ensuring the airlock is never breached. Emergency Override: Integrated safety release systems to allow for manual door operation in the event of a power failure.

Specialized Configurations
Metrolabs customizes pass-through cabinets for the specific logistical needs of high-stakes sectors:
Garment Pass-Throughs: Features internal hanging rails for the transfer of sterile cleanroom suits from laundry zones to gowning areas.
Dynamic Pass-Through Cabinets: Equipped with integrated HEPA Filters and blowers to provide active “air-washing” of bulk materials during the transfer process.
Ventilated Cabinets: Specifically designed for the transfer of volatile chemicals, featuring exhaust ports to remove hazardous vapors.
Step-Over Cabinets: Built-in partitions that facilitate the transfer of materials while simultaneously acting as a physical barrier for personnel gowning protocols.
The Metrolabs Advantage
We focus on the high-accuracy fabrication required for ISO-classified environments. A Metrolabs cabinet is not just a storage unit; it is a critical air-management component.
Zero-Ledge Exterior: Our flush-mount design ensures that the cabinet becomes a natural extension of your Cleanroom Partition Systems, leaving no external surfaces for dust to settle.
UV-C Sterilization: Optional integrated germicidal lamps provide an automated layer of surface disinfection for materials sitting within the chamber.
Digital Status Displays: High-visibility LED screens provide real-time feedback on door status and sterilization cycles.
Technical Insight: For facilities moving large quantities of liquid reagents, we recommend our Sump-Base Pass-Throughs. These feature a liquid-tight, recessed bottom to safely contain any accidental spills that may occur during the transfer process, protecting your facility’s specialized flooring.
