Re: Fwd: Cryostat phenomenon
|From:||Ej Hurley <email@example.com>|
I have encountered that same problem from time to time. It usually happens when my room ambient temperature is warmer than usual. I have found if I spray the back of the slide with a quick burst of cytocool it allieviates the problem. I hope this helps.

Been there many times over the years. Tried earthing the
microtome, whole cabinet, zapping the inside of the chamber with an
antistatic pistol but with little success. The thing I found works, to a
degree, is the Basil Fawlty. Jump up and down on the spot, curse and swear
and warn the block that if it doesn't behave you'll give it a damn good
thrashing. Failing that I just go and stare at My Little Calender Girl 2001
calender. Doesn't help the block but gets me into a more relaxed tranquil
state for the next effort.
