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.

  • Easy to use
  • Made of corrosion resistant aluminium and autoclavable
  • Collected organisms remain intact and viable
  • SureLock positive seal ensures sample integrity
  • Easy setup and calibration
  • Proven principle of operation
    • Meets ACGIH recommendations for bioaerosol sampling
    • Meets NIOSH Method 0800 and 0801 requirements
    • Performance equivalent to Andersen N-6 and Aerotech A6

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.

  • 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

† U.S Patent No. 5,902,385 (device)
‡ U.S Patent No. 5,904,752 (method)

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.

  • Applications

    • Indoor air quality investigations
    • Infection control in hospitals and veterinary clinics
    • Quantification of microorganisms in agricultural dust
    • Biological research
    • Infectious disease investigations in public buildings
    • Safety concerns in the food handling industry
    • Workplace exposures in industries such as pulp and paper mills or wastewater treatment plants

  • Specifications

    Sample Time    Up to 8 hours
    Sample Rate    Sonic flow through BioSampler nozzles (12.5 L/min)
    Sample Pump    BioLite/BioLite+ Pump
    Sample Media    Water or more viscous liquids such as ViaTrap mineral oil
    Tubing    1/4 inch ID and 3/8 inch ID

  • Analysis Options

    BioSampler samples provide many analysis options:

    • Growth Culture Analysis quantifies and characterises airborne cultural bacteria and fungi
    • Microscopic Analysis enumerates and provides limited identification of total airborne bacteria and fungi
    • Biochemical Assay quantifies biological compounds based on reaction to a chemical
    • Immunoassay quantifies airborne allergens based on antibodies binding to a specific target antigen
    • Polymerase Chain Reaction (PCR) identifies bioaerosols by screening for a specific genus or species
