[Histonet] cloudy formalin in tissue processor

[Rene J Buesa]

If you use NBF it will get cloudy when it mixes (in some step) with alcohol. The NBF has salts that are not soluble in alcohol and will produce cloudiness. You are getting your NBF mixed with alcohol.

Is your formalin picking up water from the air in the room? Check the humidity level in your room.

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.
