MicroBio Operating Manual [P0001W006]

Throughout the trials, Bioquell demonstrated that bio-decontamination with H2O2 vapour does not

appear to be detrimental in any way, effect operational aspects or aesthetics of sensitive electronic

equipment. For further information on Bioquell H2O2 vapour Material Compatibility please refer to

their document BDS-3-MATCOMP-V3.2 available from their website

Calibration

It is recommended that the MicroBio should be regularly calibrated in accordance with speciﬁc

industry best practice. Typically this will be on the anniversary of the instrument entering service.

The only calibration adjustment on the instrument is the ﬂow rate, by default set to 100 litres per

minute.

A validation/calibration kit (Cantium Scientiﬁc Limited part number P0059) for the MicroBio MB1 and

MB2 sampler is also available from your local distributor, or the sampler may be returned to your

local distributor or Cantium Scientiﬁc Limited.

Although the use of simple settle plates can be used for collection of bacterial and fungal spores, it

can never give a quantitative determination. This passive technique will also fail to enumerate very

small particles such as bacteria, which will remain suspended.

The MicroBio MB1 or MB2

bioaerosol samplers allow a quantitative measurement to be made.

The selection of the sampling volume is important for reliable sampling.

If the contact plate is

overloaded with colonies it is difﬁcult to make an accurate count. With experience, the user will

anticipate the probable bioaerosol concentration in an area, but it may be necessary to make a

preliminary survey at a number of sampling volumes to identify the optimum sampling volume. Each

sample should be repeated several times and a statistical mean value and conﬁdence value for the

value determined.
