Class III microbiological safety cabinet Bio 3+

laboratoryfloor-standingwith HEPA filter

Overview
Class III microbiological safety cabinets provide a fully enclosed workspace separating the operator from the work by a physical barrier with mechanically attached gloves. Filtered air is supplied continuously and exhaust air is treated to prevent release of micro-organisms. Envair’s Bio 3+ range are compact, high-performance cabinets intended for total operator protection when handling biological agents up to ACDP Hazard Group 4 (subject to correct installation, operation and maintenance). The cabinets deliver internal air cleanliness to ISO 5 and EC GMP Grade A (non-unidirectional airflow) and are available in multiple sizes, configurations and fumigation options. The Bio 3/1+ model can be converted between Class III mode (for ACDP Hazard Group 4) and Class I mode (for Hazard Group 3) where required.
