Bio Safety Cabinets
Biological Safety Cabinets are partly recirculating laminar airflow enclosures with high efficiency particulate air (HEPA) filtration of exhaust air and an air barrier at the work opening. HEPA-filtered vertical laminar airflow which is recirculated in the work zone creates an ultra-clean work environment for product protection. An air barrier between the operator and the work zone is maintained by a flow of room air into a full width grille in the work opening. The barrier air mixes with the laminar flow air in a sump underneath the work surface, and is exhausted to the outside environment via a HEPA filter and an optional virus burn-out. All positive pressure zones and filter seals are surrounded by negative pressure zones, so as to contain potentially hazardous aerosols.
Material of construction made of waterproof commercial ply with exterior covered by industrial laminated sheets & interiors coated with synthetic rubber paint. Side & back panels covered by lamination. Working Table Made of perforated stainless steel - satin finished Front door Made of clear Perspex sheet - vertical sliding
