Chairs for Clean Rooms
In choosing seating for Class 10 to class 10000 Cleanrooms or indeed simply for “super-clean” environments as found in some laboratories, it is well to be aware that – We Get What We Pay For! For areas requiring an extremely low particulate burden we supply BioFit chairs that use a filtration system within the seat. The Class 100 system traps particulates while allowing the seat to conform to body shape. The filter allows unrestricted airflow with an entrapment of particles 0.1 micron or larger. Class 1000 areas (and above) do not require HEPA filter system: in seating features plugged tubular chrome plated or cast aluminium bases and chrome-plated metal parts. These chairs are built on the same frame as all other BioFit Cleanroom chairs. The vinyl under wrap under the seat matches the vinyl upholstery and entirely covers the baseboard of the seat. BioFit seating is tested following a Test Method developed by Inter Basic Resources that is designed to evaluate particulate cleanliness by means of particle analysis. The testing isolates and counts the Federal Standard 209E. BioFit static control chairs and stools can be either conductive or dissipative depending on the upholstery chosen. There is a wide variety to choose from. Chairs can be supplied with appropriate castors or with glides, with or without footrests and armrests. Seat height is adjustable of course.

Safety Cabinets for Clean Rooms
The manufacture of Safety Cabinets for Clearooms require materials, design and construction methods that do not result in particulate generations in the environment. The storage of hazardous substances within a Cleanroom area has to be considered according to their properties:- flammable / toxic / caustic or water polluting. Each cabinet we offer is manufactured to meet or exceed DIN EN 14470-1: DIN EN 14727: DIN EN ISO 146441-1. Further details are available on request.
