[Histonet] tissue swelling out of block

From:"Gudrun Lang"

Hi all,

a friend recently got a job in a veterinary histo and has some troubles in
cutting. He tells about paraffinblocks, where the tissue is swelling out
while warming like a small hill.  I referred to the possibilty of taking up
humidity that causes swelling. 

Do you know other causes for this problem?


Thanks in advance

Gudrun Lang
