Hey Histonet,
We have a client who is having an odd problem with their processor. They
are getting "sandy" clogs in station 3. The original thought was that it
was formalin salts but the texture and color was wrong. Also, station 3
is 70% which should be weak enough. One of the techs mentioned
My guess is that either your 70% wasn't made up properly and was a higher
concentration or it's been so long since you've changed the solution that
the water is fully saturated with the formalin salts. If it becomes a
regular problem, you might consider reducing your first alcohol's
concentration

Hello
Phosphate buffered formalin followed by concentrated alcohol will produce
these phosphate salts. To prevent this, formalin should be followed by
alcohol of 70% or less. Also, when you change your processing solutions,
you can do a water flush (we do first 4 solutions - 2 formalin 2 alcohol) to

Hello Everyone,
Has anyone ever seen a (salt?) precipitate in their alcohols following
formalin? While changing the processor this morning, I noticed a precipitate
in the 80% alcohol and 95% alcohol (NOT in the 70% alcohol). It is white and
grainy. The alcohols were otherwise unaffected.
