IV. Usage and Maintenance
-
Usage Precautions:
-
Separatory Funnel: The ground-glass stopper must be original and well-fitted; a leaking funnel should not be used.
-
Test Tubes: Hard glass test tubes can be directly heated but should not be subjected to sudden cooling. Centrifuge tubes should only be heated in a water bath.
-
Condensers: Cooling water should enter from the bottom and exit from the top to prevent sudden cooling or heating.
-
Desiccators: Place desiccant at the bottom; do not place red-hot objects inside.
