In the realm of biological safety, the transfer of materials between areas of different safety levels is a critical process that requires meticulous attention to detail. QUALIA’s Biosafety Pass Boxes are designed to meet these stringent requirements, providing a robust and efficient solution for laboratories and medical facilities.
Key Features of QUALIA Biosafety Pass Boxes
Sealing Options and Integrity
QUALIA’s Biosafety Pass Boxes offer two sealing options: inflatable seals and mechanical compression. The inflatable seals are made from high-density EPDM (Ethylene Propylene Diene Monomer) with a hardness of 60±5° Shore A, ensuring a long service life of over 5 years. These seals maintain a pressure decay of less than 0.5% Vol/h at ±2000Pa over 20 minutes, exceeding industry standards.
Sterilization Methods
These pass boxes are equipped with multiple sterilization methods, including UV disinfection lamps and VHP (Vaporized Hydrogen Peroxide) disinfection ports. The VHP system, which can be connected to an external VHP generator, ensures thorough sterilization by producing a hydrogen peroxide mist that effectively kills a wide range of microorganisms, including bacteria, viruses, fungi, and spores.
Door Construction and Safety
The doors of the pass boxes are constructed from fully welded 3.0mm stainless steel sheets and feature double-layer 5mm tempered glass. The design includes concentric circle corners with inner rounded arc welds and thorough sanding to ensure user safety and minimize the risk of glass breakage.
Advanced Features
- Temperature Stability: An optional feature maintains temperature variations within ≤3℃, ideal for sensitive biological transfers like serum.
- Functionality Switch: Users can switch between VHP sterilization and standard self-cleaning UV modes via a touchscreen.
- BMS Communication: The pass boxes facilitate integration with BMS systems for online and remote printing, as well as data storage capabilities.
