How to fill a melting point capillary

First, be sure that you have the right capillary for the machine you are going to use. There are two different mp machines in the lab. One is digital and uses slightly smaller capillaries than the older machines. If you force the old, larger capillaries into the new machine, they will get stuck and will take the new digital mp’s out of service. Please be careful.

Please the opened end of the capillary onto the pile of crystals. The closed end should be pointing up. The crystals will be held in the tube.

Turn the tube right side up and tap on the bench top. The crystals will fall to the closed end of the capillary.
