[Histonet] Acid Phosphatase Reaction

Hello to all Histologists,
Perhaps someone can help me.  At our institution we primarily use electron microscopy for slides with toluidine blue, and grids for TEM.  The students here also do some immunostaining on their tissues.  We have a student though who would like to try using the Acid  Phosphatase Reaction to identify lysosomes as another alternative data to add to his paper.  Not having done any type of paraffin sectioning before how would we proceed?  I understand the basic tissue processing recipe with formalin, however does the procedure call for a special machine?  I noticed that all the recipes I have looked at online refer to using cassettes.  We primarily use microwave and vacuum to process our tissue in Karnovsky's for TEM.  Would the xylene cause any problems for us?  Are there any other stains that could work on resin embedded sections besides toluidine blue that would specifically stain lysosomes?  You advice would be greatly appreciated.

Thank you,
