[Histonet] cryostat decontamination

With the Vibratome 7500 Cryostat, decontamination involves pressing a button and doing something else for 3.5 hours, after which the instrument is thoroughly decontaminated, again cold, and ready to cut tissue.  Before the next decontamination cycle, empty the waste bin down the sink, and refill a bottle of water and a bottle of Perascope decontamination fluid.  That's all.  For more information on how this is accomplished, see the following link:

Laura,

We have a protocol for decontaminating all our Cryostats once per week.  We
have 2 Shandon 660E models which have the heating block which you fill with
40% formadlehyde then turn on the decontamination cycle.  This is performed
overnight Friday.  After this process the shavings are removed using tissue
damped with 70% ethanol.
The others have a formaldehyde "bomb" prepared and placed into the chamber,
then left sealed to defrost for 24 hours.  These are then cleaned using 70%
ethanol.

The same procedures are carried out if we have cut anything suspected of
being an infective agent, immediately after the case is finished.

We have the luxury of two cryostats available in our main laboratory.

All the best

How do others clean the cryostat after a known or suspected TB case?  Also,
do you decontaminate once a week with a tuberculocidal antiseptic?
