Checking of aerosol-tight bio-containment
The checking of the rotor type and bucket was done
according to the dynamic microbiological test proce-
dure with regard to EN 61010-2-020 appendix AA.
The aerosol-tight bio-containment of the rotor mainly
depends on proper handling!
Check the aerosol-tight bio-contain-
ment of your rotor whenever
necessary!
It is very important, that all the seals and
seal-surfaces are being tested for wear and
damages like cracks, scratches and embrit-
tlement carefully!

As a quick test there is the possibility to check the
aerosol-tight buckets and fixed angle rotors according
to the following procedure:
•
grease slightly all seals.
•
Fill the bucket or rotor with approx. 50 ml carbon
dioxide mineral water.
•
Close the bucket or rotor according to the respec-
tive handling instructions.
•
Shaking the bucket releases the carbon dioxide of
the water, and an excessive pressure is built up.
•
Leaks are recognized by humidity release and
audible disinflation of gas mix.
•
Finally buckets respectively rotor, lid and lid seal
have to be dried.
