BioStage

The BioStage single-stage cascade impactor operates on the principle of inertial impaction and meets NIOSH requirements and ACGIH recommendations for sampling indoor and outdoor air for viable microorganisms including bacteria and fungi. Made of precision-tooled aluminum, the sampler components are held together securely by the SureLock positive seal. Using a high flow pump such as the BioLite, air is drawn through the impactor where particles are impacted onto an agar collection medium.

BioSampler

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

BioSampler

  •  
  • Allows use of non-evaporating collection liquids
  • Patented swirling liquid collection method minimises re-aerosolisation and particle bounce
  • Preserves micro-organism integrity and viability
  • Reusable — can be autoclaved
  • Maintains constant sampling efficiency up to 8 hours
  • Collected bioaerosols can be analysed by a variety of methods
  • Complete glass construction allows easy cleaning, sterilising, autoclaving and reuse
  • Collection liquid easily ransferred to agar plate for culturing

BioSampler Operation

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. Collection liquid with a viscosity much higher than water, such as ViaTrap (special mineral oil), can be used with the BioSampler to provide constant collection efficiency over an 8 hour sampling period.
