Biological Containment

Whitley H35 Hypoxystation

Looking for extra biological containment from your workstation?

If you need additional biological containment within your HEPA filtered Workstation, there is now an option to reduce biological discharge from the chamber via the gas outlets. The Whitley Enhanced Biological Containment System involves fitting HEPA filters to the two gas outlets on a Whitley HEPA Workstation.

Laboratory tests were conducted on an H35 Hypoxystation to deliberately challenge the exhaust filters with high concentrations of aerosolized bacterial cells and quantify their discharge through the exhaust valve filters.

The results of this experiment demonstrated that the system achieved a substantial reduction in bacterial loading (better than 99.999%) within the discharged gas. A paper detailing the full methodology and results of this study can be found here.
