[Histonet] Contamination on Processor

It's more likely due to the presence of lipids extracted from the tissues.
How often do you replenish/change alcohols?

Subject: [Histonet] Contamination on Processor

We are experiencing cloudiness in all of our alcohols on our processor. We 
test them before we dump them by mixing them with water and they cloud up. 
To me this says there is some clear-rite/xylene (we use both on our 
processors) getting in them somehow. I was wondering if anyone else has 
experienced this or if there is a possibility it could be some other 
contaminant or is the cloudiness normal after so many processing runs. We 
have newer processors, leica asp300s. Any help would be so much appreciated. 
thank you.
