[Histonet] Formaldehyde Vapors

[Walter Benton]

Are you using the potassium permanganate filters? Are you evaluating and changing them as needed. Instructions to evaluate the pellets are listed on page 120 of the Mopec catalogue and probably can be found online. Basically the test has you check the pellets for color, Purple = New, Dark Brown the pellet is spent. We have used these filters for a while now and find that they work well provided they are changed at appropriate intervals.

Good Morning Histo Land, I was just informed that on my last test sample
for formaldehyde vapors was very high.  Right now I have to wear a
respirator while grossing and assisting grossing.  We are looking at why
the Mopec grossing station is not working in fact we have not had really
good results since we put it in.  I'm wondering if anyone else is having
the same problem or know of a better solution.  Our grossing station is
the one that is self contained with filters. Also is anyone using with
good result a formalin substitute? If so which one? 
Thanks and Have a great day,
