Glassware

1. When using glassware in the lab, it
is important to use it properly to ensure that you avoid spills or breakages. 2. Always inspect the glassware before
using it to ensure that it does not have any cracks. 3. Be sure to clean your glassware at
the end of the lab thoroughly. Be careful when cleaning the glassware. Most
cuts occur when students are cleaning their glassware. 4. When assembling a glassware setup
for a reaction, be sure to clamp the glassware properly. Do not use too many
clamps because too many makes the setup inflexible. Do not use too few clamps
because it may result in the setup falling apart and breaking the glassware.
Also use a Keck clamp wherever you have two pieces of glassware connected by
a glass joint. 5. Be sure to grease all joints
properly when instructed to do so. 6. Be sure when using the thermometer
adapter that it is inserted properly. 7. If you are using a rubber-septa, be
sure that it is inserted properly. 8. If you break any glassware, let
your TA know immediately. Then clean up the mess if it is small enough for
you to handle it. Be sure to be careful not to cut yourself and place the
broken glass into the proper container. 9. Be sure to use the correct size of container when getting a chemical. If you need 50 mL, do not use the 50 mL beaker (use a larger one to avoid spills). |
