I do not thing such a thing is even theoretically possible.  Kill TB germs buried in ice? 

Get a self decontaminating cryostat, and do the job overnight while you sleep.

Subject: [Histonet] DECONTAMINATING CRYOSTATS


Lately we have done several frozen sections on lung cases that have turned out to be possible T.B. cases. We then have to shut down our cryostats, defrost them and decontaminate them Does anyone know of any decontamination procedures that does  not require the total defrosting of the cryostat.
