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!
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.
It is very important, that all the seals and
seal-surfaces are being tested for wear
and damages like cracks, scratches and
embrittlement 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.
Check the aerosol-tight bio-contain-
ment of your rotor whenever
necessary!
The construction of BIOshield
®
- and
Highplate
®
- rotors does not allow a
quick test according to this procedure
by the user; therefore a very careful
control of seals, seal surfaces and
lids is necessary!
