[Histonet] A Question About Paraffin Times

[Weems, Joyce K.]

Must better to remove them on Sat than to leave in the hot paraffin. We do this all the time so we can meet the CAP time in formalin for the breasts.

Good luck! j

Subject: [Histonet] A Question About Paraffin Times

Good Morning Listers,

I am asking the collective wisdom of the Histonet this question:


Is it better to remove baskets from the processor on Saturday morning and:

A.  Let the cassettes freeze, then melt them down and embed Monday morning?
OR
B.  Leave the cassettes in molten paraffin and embed Monday morning?


I am of the opinion that leaving the samples (not fatty, like breast cores) in molten paraffin (62 degrees C)  is bad practice, and causes them to get "crunchy", among other things.

What do you think?

Thank in advance.

Sincerely,

Paula Sicurello, HTL (ASCP)CM
