7.1.2 Paraffin cleaning
It is possible to clean used paraffin of solvent
residues (xylene) in the Leica ASP200 S.
To do so, select the paraffin bath for which the
paraffin should be cleaned in the CLEANING
PROGRAMS menu.
If the last reagent in the retort is not compatible
with paraffin, carry out a retort cleaning first.
The following steps are taken during the paraffin
cleaning:
• The paraffin is pumped into the retort.
• There it is heated to the highest possible tem-
perature.
• The retort is put under vacuum, causing the
solvent vapors to be drawn out of the paraffin.
