[Histonet] cloudy formalin in tissue processor

The old tissue processors used to have cloudy formalin to the point
you'd get a layer at the bottom of the jars. If it is not contamination
from the clearing fluids already suggested, could it not just be the
fixed protein from the tissues that is held in suspension. I would have
thought very bloody or very proteinaseous tissue would have these labile
proteins fixed which would then fall out of solution; from memory the
cold makes it worse.

Subject: [Histonet] cloudy formalin in tissue processor

Has anyone had a problem with their formalin getting cloudy in their
tissue processor? We have a VIP tissue processor and just recently
started having problems with cloudy formalin. Any suggestions would be
appreciated. I checked the archives and couldn't find any articles on
this particular subject. Thanks.
