Cleaning
The sampling head should be sterilised preferably by autoclave, but in the
field disinfect with suitable sterilising wipes, such as IPA wipes or Tuffie-5
wipes. Wipes may also be used for general cleaning of the sampler body. In
areas of low bioaerosol levels, observe a disinfection regime between each
sample. Always sample from areas of lower contamination towards those of
higher contamination. Wash exposed skin and clothing before sampling and
avoid drinking, eating and smoking in the test area. All equipment should be
handled aseptically.
The MicroBio MB2 is suitable for use with Hydrogen Peroxide Vapour (H
2
O
2
vapour) bio-decontamination. As the MicroBio MB2 has a fan within the
sampling head, it is recommended for optimum decontamination the
MicroBio MB2 is set to sample at maximum volume, allowing H
2
O
2
vapour to
be drawn through the head, fan and exhaust.
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:
Vapour sterilisation above the test conditions
levels and times will invalidate the warranty
.
Throughout the tests, Bioquell demonstrated that bio-decontamination with
H
2
O
2
vapour does not appear to be detrimental in any way, affect operational
aspects or aesthetics of sensitive electronic equipment. For further
