The release rate of the suppository is related to its melting point; it is therefore critical that this test be evaluated using a non-destructive method. A number of different techniques are used to study melting behavior, including the open capillary tube, the U-tube, and the drop

The melting point of an organic solid can be determined by introducing a tiny amount into a small capillary tube, attaching this to the stem of a thermometer centred ...

The height of the sample in the capillary should be about 2-3 mm. Insert the sample in the apparatus and determine the melting point. The speed of heating should be adjusted so that near the melting point the rate does not
Chapter 2 Measurement of Temperature
www.jma.go.jpThe boiling point of methyl alcohol is 64.65 °C, and its melting point is -97.78 °C. Because mercury has low thermal capacity, high heat conductivity, inertness in relation to a glass capillary tube and a high boiling point, it is an ideal thermometric liquid except for its relatively high melting point. Accordingly, mercury
