Appendix A: GlassChem 20 Vessels
Corporation if assistance is needed creating a new method.
• “Vessel Type” = “Glass Chem”
• See “Operating Parameters” in “Appendix A” before programming method parameters
4. With the door open, use the Turntable Icon to rotate the turntable. Observe the positioning and balance of the
turntable. Make adjustments by reseating the turntable if necessary.
5. Close the instrument door.
6. Select “Start” to run the method. The instrument will begin the method according to the selected parameters
– initializing, ramping, holding, cooling, etc.
NOTE
If a run is stopped during the reaction, do not restart the method with hot vessels. Allow vessels to cool to
50 °C, vent vessels and reseal, and restart method from the beginning.
CAUTION
Observe the entire reaction sequence when establishing a procedure for the rst time.
7. During the run, the user can select the applicable image on the left side of the screen. If the line graph is se-
lected, the user can select the icons on the right side of the screen to display the desired parameter(s).
8. After completion of the method, permit the vessels to cool in the microwave cavity to 50 °C and then an addi-
tional 10 minutes.
Vessel Removal
1. Allow the vessels to cool in the microwave to 50 °C and an then an additional 10 minutes.
WARNING
To prevent the possibility of severe burns, ensure that gloves and protective gear as outlined in your safety
program are worn.
2. Disconnect and remove the ber optic probe.
3. Remove the turntable, keeping the vent holes pointed away from the user at all times, and place into a fume
hood.
4. Remove the shield from the turntable.
5. Remove the vessel assemblies from the turntable one by one, keeping the vent hole pointed away from the
user.
6. With the vent hole pointed away from the user, slowly and carefully loosen the caps, allowing them to vent. Do
not rapidly loosen the cap as this will permit gases to escape quickly resulting in potential injury.
7. Remove the cap and vent plug.
8. Place the vessel into the vessel holder rack and proceed with work-up.
9. Clean vessels as outlined in “Vessel Cleaning ” section.
