that might over-dry one's delicate samples.
I gather that depending on what machine you have you can apply pressure
at each step or just at the final paraffin stage ( as in my case).
Here is my question... would applying pressure during the fixation of
the tissues also be beneficial?
Would it speed up the process therefore minimizing the possibility of
Do any of you fix tissue under pressure and, if so, how do you go about
it?  Just curious....
