I have a problem with this, if you can clean a cryostat with a vacuum
(biohazardous tissues, etc) then how do you clean the vacuum?? The latter
would present the same problems UNLESS they are manufactured in such a way
they can be disinfected intact or some other way that does not overly
expose workers to the nasties.  Seems to be a trade off of one problem with
another to deal with.  

In short, I prefer to clean a cryostat by hand (with proper safety
equipment) after use, daily or whatever is needed.
