Biological safety cabinets are the primary barrier against exposure to aerosols that may be produced from common microbiology procedures. In addition to protection for personnel and the room environment, many work programmes require that products are protected from airborne contamination. BH2000 Series cabinets provide personnel, environment and product protection in applications involving biological agents which are classified as being of ordinary, potential or special hazard. These cabinets are not designed for use with biological agents of extreme hazard. For applications involving cytotoxic drugs, CG2000 Series Cytogard cabinets should be specified.
Australian and International Standards
BH2000 Series cabinets are part-recirculating laminar air flow enclosures with high efficiency particulate air (HEPA) filtration of exhaust air and an air barrier at the work opening. HEPA-filtered vertical laminar air flow 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 room via a HEPA filter. All positive pressure zones and filter seais are surrounded by negative pressure zones, so as to contain potentially hazardous aerosols.
Standard cabinets have exhaust discharge on the right hand side. Optional left hand side or top exhaust is available. Cabinets are produced with a work zone width of 90cm, 120cm or 180cm and may be installed on standard laboratory benches or on optional floor stands. Embodying advanced system-monitoring technology, enhanced ergonomics and styling, BH2000 Series cabinets set a new standard in safety cabinet design and performance.
Constructed in electro-galvanised steel with joints welded using a gas-shielded arc process. This method produces a robust, gas-tight housing which is able to withstand the rigours of transport and handling. Exterior finish is in a special baked enamel which has been developed for laboratory equipment.
Constructed in Grade 304 stainless steel with 2B finish. Corners are radiused and crevice-free for ease of cleaning and all surfaces are carefully dressed to remove sharp edges. The removable work tray is designed to allow cleaning access to its underside without removing it from the cabinet. A removable panel provides cleaning and service access to the rear plenum.A pneumatic mechanism assists the opening and closing of the viewing window without the need for external fasteners or catches. The window is self-supporting in the fully-open position to facilitate cleaning and access for large items. Opening the window with the cabinet running automatically engages a boost mode for enhanced containment by activating maximum exhaust airflow and the alarm systems.
