No statement can be made about the resulting degree of sterility.
The lids of the rotors and bucket must be removed before autoclaving.
Autoclaving accelerates the ageing of materials. It may cause changes to
colours. After autoclaving, the rotors and accessories are to be visually
inspected for damage and any damaged parts are to be replaced immedi-
ately.
The sealing ring in question is to be replaced if there are signs of cracking,
embrittlement or wear. For lids with non-replaceable sealing rings, the whole
lid must be replaced.
