Change Plate/Dish Type
The MicroBio can accommodate both 55mm contact plates or 90mm Petri style dishes. The MB1
and MB2 samplers are factory fitted with the Petri dish springs, but these can be removed and
replaced with contact plate springs (Cantium Scientific Limited part number P0001M007). The
springs for both types have slots to allow a degree of adjustment to suit dish/plate manufacturer
variations.
The picture below shows the fitting of the contact plate springs.
Care must be taken not to over-tighten or cross-thread any of the screws. The tool required is a
small Pozi-head screwdriver (Cantium Scientific Limited part number P0001SCRD). If any screws
are lost, they can be replaced with Cantium Scientific Limited part number P0001SCR003.
Cleaning
The sampling head should be sterilised preferably by autoclave, but in the field disinfect with
suitable sterilising wipes (Cantium Scientific Limited part number 901SW225TY).
In areas of low bioaerosol levels, observe a disinfection regime between each sample.

Tests have been carried out by Bioquell (UK) Ltd on a range of sensitive electronic equipment to
determine effects of such processes. The conditions of these tests were:
Gas Concentration
Conditioning time
Gassing time
Aeration time
As the MicroBio has a fan within the sampling head head it is recommended that during the
decontamination process the MicroBio is set to sample at maximum volume so that the H
may be drawn through the head, fan and exhaust for optimum decontamination.
