While there is no standardised method for bioaerosol collection at this time, many organisations, including SKC, are researching improved measurement techniques. The patentedBioSampler® is a result of SKC’s work with leading scientists at the University of Cincinnati.

The BioSampler® must be operated with a high volume sonic flow pump, such as the BioLite/BioLite+Pump, that can maintain 15 inches mercury or 0.5 of an atmosphere of downstream pressure in the system. The BioSampler’s three tangential nozzles act as critical (sonic) orifices, each permitting 4.2 L/min of ambient air to pass through for a total flow rate of approximately 12.5 L/min.
