BioSampler
8-hour Sampling of Bioaerosols into Liquid
• Design overcomes problems associated with impinger sampling of bioaerosols
• Allows use of non-evaporating collection liquids for longer sampling times
• Maintains constant sampling efficiency up to 8 hours
• Swirling liquid collection method
– Significantly reduces particle bounce and re-aerosolization
– Preserves microorganism integrity and viability
• Collection liquid easily transferred to agar plate for culturing
• Samples can be analyzed by a variety of methods
• Reusable — can be autoclaved
The SKC BioSampler® is a glass collection device that externally
resembles an All-glass Impinger (AGI-30‡). Internally, BioSampler
contains design features that overcome some of the sampling
problems associated with using impingers for bioaerosol collection.
• Inlet limits collection of airborne particles to those that would pass through the human nose.
• Three tangential nozzles reduce particle bounce off inner wall.
• Airflow through the nozzles causes the collection liquid to swirl upward on the inner wall and gently remove collected particles. The swirling motion generates few bubbles and minimizes re-aerosolization of particles.
The BioSampler Advantage
• Constant sampling efficiency over longer sampling times
BioSampler : Thicker, non-evaporating liquids such as ViaTrap® mineral oil can be used to maintain constant sampling efficiency over an 8-hour workshift. Longer sampling times increase sample volumes for detecting organisms at lower concentration levels.
Standard Impingers : Typical sampling times with standard impinger liquids are only 1 to 1.5 hours.
• Less particle bounce
BioSampler : Nozzles eject particles at an angle to the sampler’s inner wall to reduce particle bounce and preserve aggregates of organisms.
Standard Impingers : Microorganisms are typically damaged by collision with the impinger base plate.
• Decreased particle re-aerosolization
BioSampler : Airflow through three tangential nozzles causes the collection liquid to gently swirl and move particles into the collection liquid without re-aerosolization.
Standard Impingers : The collection liquid tends to bubble violently, causing collected particles to re-enter ambient air.
