Cleaning the Stage
Dirt or sample residue left on the top of the stage may interfere with the next sample placed on the stage. To
maintain proper experimental conditions, clean the stage as follows:
For small amounts of residue:
1.
Use industrial cleaner or acetone on a soft cloth to wipe the top of the stage.
For thorough cleaning:
Refer to the figure to the right when needed.
1.
Raise the furnace, and rotate it clockwise to move it off
to the side.
2.
Remove the stage shield by lifting it straight up. (This is
a friction fit.)
3.
Take off the spring clip that holds the sample thermo-
couple, and move the thermocouple off to the side of
the stage.
4.
Turn the stage nut counterclockwise to remove it.
5.
Twist the stage retainer ring (with key slots) counter-
clockwise, pull it up off the posts, and slide it up off the
stage.
6.
Take the wave washer up off the stage flange, and
remove it.
7.
Remove the stage from the stage opening.
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.
10. Reassemble the stage, stage shield, etc. by reversing steps 6 through 2.
