For Operator, Product and Environment Protection
Bigneat Class II,biological safety cabinets are built to a very high standard, using only the best quality materials, microprocessor and fan components. A premium level of operator, product and environmental protection offered at an economical price.
Many year's of experience and customer feedback has lead to the development of this range which offers excellent access, visibility of the working area, and maximises operator comfort.
Description of operation and protection
ULPA filtered supply and exhaust air protects the operator, the process and the environment.
Room air is drawn past the operator entering the cabinet via the front grille, but does not enter the cabinet interior. This protects the operator from exposure to the potentially hazardous materials inside the cabinet. The working interior is in turn blanketed in clean, sterile air preventing product contamination.
The inflow air velocity, downflow air velocity, airflow path and intake geometry are precisely tuned and tested to create an optimum air curtain at the front of the cabinet.
Performance
Cabinet performance is guaranteed by use of ULPA filters, providing 99.999% efficiency for particle sizes of 0.1 to 0.3 microns. The supply filter provides ISO Class 3 laminar flow clean air to the work surface.
Continuous monitoring of the cabinet airflow is displayed on an LCD panel. Audible and visual alarms in case of malfunction/incorrect conditions.
Bigneat Class II cabinets are suitable for agents classified under Biosafety levels 1, 2 and 3.
