Hello Histofolk,

Does anyone out there in Histoland use Fisher TissuePrep paraffin? If
so,have you been having trouble with it being on back order?  This has
happened to us twice in the past couple of months.  The last time it was
several weeks before we received it.  We had to use Paraplast Plus as a
substitute which the techs do not like.  Any recommendations for another
replacement?  Is it necessary to empty all processors, embedding units etc
of TissuePrep before changing over to another paraffin?
Thanks in advance.
