LABORATORY EQUIPMENT

 

Four decades of manufacturing innovative equipment to protect personnel, product and the environment. 

HOOD CLASSIFICATIONS:

Class I is a ventilated cabinet with an inward airflow and outlet HEPA filters.  It was previously referred to as the CDC Hood and served a valuable function in its time by protecting personnel and the environment.  Because it offers no product protection, it has been essentially obsolete for several decades. 

Class II (types A and B) are Laminar Flow Biological Safety Cabinets that protect personnel, product and environment.   They provide inward airflow to protect personnel, downflow HEPA filtered air to the work area to protect the product, and exhaust HEPA filtered air to protect the environment from particulate and aerosol hazards. 

Class III cabinets are defined as ventilated Gloveboxes.  These are gas-tight chambers operated through sealed gloves which provide a complete separation of the worker from hazardous materials.  The Glovebox is maintained under negative pressure with HEPA filtered supply air and double HEPA filtered exhaust air.
