We are often asked ‘how can MicroBio samplers be that good at sampling compared to others costing more than twice as much?’ The simple answer: the impaction velocity of organisms is kept low enough, between 9.8 and 11 metres per second for MicroBio sampling heads, so their viability is not compromised when impacting upon sample plates, but not too slow as to flow through the air stream and miss the plate altogether! Our sampler design concentrates on viable bioaerosol collection rather than the aesthetics of the product.  What’s important is capturing a viable sample, rather than just looking the part. Research has shown (Stewart et al, Appl Environ Microbiol. Read More …
