8. Use industrial cleaner or acetone applied
with a soft brush or cloth to clean the stage
surface.
9. Heat the stage surface with a Bunsen burner
until the residue evaporates and the stage is
clean. Heat the stage very slowly if the
sample contains a large amount of mineral or
glass filler.
The stage may also be cleaned in a nitric
acid solution.
Cleaning the
Thermocouple
Sample residue and dirt may interfere with the
accuracy of the thermocouple readings. To clean
the thermocouple:
1. Raise the furnace and rotate it clockwise to
move it off to the side.
2. Remove the stage shield.
3. Remove the spring clip holding the thermo-
couple in place.
4. Hold the thermocouple away from the probe
assembly, and clean it gently with a low
flame using a hand-held burner.
