      I recall that it should pull 20-25 mgHg.

Hi all,

We recently inherited a vacuum oven for hand processing paraffin blocks.
Actually, I don't know what the oven was originally used for, but we want
to use it to process paraffin blocks.
It can be set at any pressure we want, but I don't know the pressure that
is needed for parafin processing and I can't find it listed in any of my
histology texts.  Anyone out there know what it is off hand?

Thanks in advance,
