Melting points are important for determining the purity of solid products. A small amount of sample is packed into the closed end of a capillary tube with a wire or small glass rod. It is then attached to a thermometer, keeping the sample next to the bulb. Next submerge into oil filled tube, keeping setup in the middle of tube (do not touch the sides or bottom). Watch for temperature at which solid sample melts.
