RE: [Histonet] Temp/Humidity Records?

From:"Pamela A. Marcum"

The comment for the records were regarding IHC and yet I find changes in
humidity and temperature have more effect on my sectioning and mounting of
paraffin and plastic sections.  If you are doing automated IHC I don't see how
this would matter.  If it is manual and you use a humidity chamber it still
won't matter much.  I could only see this mattering to IHC if it is done on the
bench in open air.  The changes I get seasons change throughout the day as heat
or AC are added or changed.

Is this really a new requirement??
