How do I filter the exhaust gases from a Whitley Workstation?
WHITLEY WORKSTATION – FILTRATION OF EXHAUST GASES There are instances when customers wish to filter the exhaust gases from a workstation. This would normally only occur after a laboratory has carried out a Risk Assessment and identified a need to prevent the potential egress of hazardous organisms into the laboratory environment. MODIFICATIONS The Whitley range of workstations can be modified to provide for filtration of the exhaust gases. In principle the output gases from the pump and the oil equilibration system are filtered. Additionally the evaporator is replaced by a separate sealed condensate system which has to be emptied manually. Workstations with this modification operate on non-standard software such that an airlock exit cycle has to be run before plates can be removed from the airlock. This flushes the airlock with nitrogen thereby diluting the microbial load within the airlock. It is important that the customer also considers the laboratory protocol to be used in conjunct
