Introduction - Cantium Scientific MicroBio MB1 Operating Manual

Introduction

The MicroBio MB1 is part of the MicroBio range of bioaerosol samplers and
is one of the most economical hand-held samplers in the world for
monitoring airborne micro-organisms or bioaerosols.
The MicroBio range meets the standard required for a reference sampler, as
fully validated by the UK Department of Trade and Industry Validation of
Analytical Methods (VAM) programme.
The sampler collects airborne micro-organisms by drawing a stream of air at
a constant flow rate through a series of small holes in a metal head.
Particles suspended in the air stream impinge onto the surface of a sterile
culture medium in a contact plate or petri dish.
After exposure to a set volume of air, the contact plate or petri dish is
removed and incubated. The number of colonies which develop are
counted, enabling a calculation to be made to determine the concentration of
micro-organisms in the air (CFU / m 3 - colony forming units per cubic metre).
