Double chamber class 3 biological safety cabinet

Our Class 3 biological safety cabinets are designed to provide airtight containment for the safe handling of hazardous materials. Increasingly, customers have requested multi-chamber Class 3 setups – joining two or more cabinets together to create a continuous, sealed workflow for complex processes. 

To meet this growing demand, we developed a fully customised solution that links multiple Class 3 cabinets using sealed transfer hatches, allowing materials to move through each process stage safely and efficiently, without ever leaving containment.

Project Goals 

The key objectives of this project were: 

  • End-to-End Containment: To allow an entire multi-step process to take place within one joined, fully sealed system 

  • Safe, Controlled Transfers: To minimise handling risks by eliminating the need to move materials in and out of containment between stages 

  • Operational Efficiency: To streamline lab workflows and reduce the chance of contamination or spills 

the result

Our solution features a fully integrated multi-cabinet Class 3 system, designed with: 

  • Sealed transfer hatches between each chamber, enabling safe and efficient handover between process steps 

  • Entry and exit transfer hatches on the side of the first and last cabinets, allowing controlled introduction and removal of materials 

  • A continuous, airtight containment path that supports sequential workflows without breaking the containment chain

  • Flexible installation options, with units available either worktop-mounted to fit onto existing lab furniture or supplied with support stands for standalone placement 

In Summary

This configuration allows materials to enter through the initial transfer hatch, be worked on in the first cabinet, then safely passed through to the next cabinet for subsequent steps, and finally removed from the final chamber – all under full containment at every stage. 

The result is a safer, more efficient laboratory environment, reducing the risks associated with moving materials between isolated systems and enhancing process control throughout.
