Subject: Re: Disinfecting The Cryostat?It's always been my understanding that bleach coorodes the metal becuase it doesn't evaporate like it does at room temp. When we have a TB case and they mistakenly use the cryostat that doesn't self decontaminate, we put a small container of formalin in it and don't use it untill the formalin freezes. Then we clean out all the shavings and start anew.... I don't know where that came from though...
