Biological Safety Cabinet

BIO II A cabinet provides personnel, environmental and product protection in applications involving biological agents. These cabinets have been designed according DIN 12950 and are meeting or exceeding requirements of NSF 49, BS 5726 and NFX 44-201.

Each cabinet is factory-certified by TÜV-GS registered laboratory to meet the specified performance requirements.

Control System

Main switch with key and microprocessor control system. Alphanumeric luminiscent display provoding following data:

• Exhaust air flow m©ø/h.
• Laminar flow air velocity m/s.
• Cabinet temperature ¡ÆC.
• Fans elapsed hour meter.
• U.V. lamp elapsed hour meter.
• HEPA filters last change date.

Safety and regulation systems controlled by the microprocessor. Visual and auditory alarms shown on the display:

• Low exhaust flow.
• Low downflow air velocity.
• Exhaust fan malfunction.
• Front window opened.

Control system is also providing safety features as:

• U.V. interlocking when front window is open.
• Air flow and lighting interlocking when U.V. lamp is on.
• Impulsion and exhaust fans providing a double safety system: In case of eventual stop of the exhaust fan, the impulsion one is authomatically stopped. In case of eventual stop of the impulsion fan, the exaust one increases its speed in order to maintain underpressure conditions in the working space.
• Microprocessor compensates for gradual increase in filters resistance: inflow and downflow are maintained in any condition.

General Features

BIO II A cabinet is 70% recirculating down flow enclosure Class II A equipped with two high efficiency HEPA filters:

• HEPA filtered laminar air flow Class 10 which is recirculated in the work zone creates an ultra clean work environment for product protection. A room air barrier at the front opening prevents escape of pathogens into the worker's area.
• Exhaust HEPA filter provides safety to environment.

Stove-enamel coated steel cabinet. Easy access for working and cleaning. Working space in stainless steel AISI 304. Segmented working surface. Laminated safety front window with gas springs. Two HEPA/ULPA filter stages H 14 efficiency 99,999% for particles >0,3¥ìm easily accessible for replacement.

Vertical down flow filter, exhaust filter and fans accessible from the front provide easy maintenance.

Lighting system outside working chamber makes service easier.

Possibility to connect remote fan in ducted cabinets.

Special model with lead protection for radiosotopes preparation.
