The glass capillary having one end closed and one open end is generally used for the determination of melting point of the sample. From the open end, the sample is put into the capillary, the sample must be firmly packed as the melting point is an intrinsic property that means it is independent of sample size. So, in order to determine the melting point of the sample small sample in the capillary is sufficient to measure the melting point of the sample. To obtain the more consistent value of melting point one must pack the sample firmly in the capillary.
Hence, when determining the melting point of a substance, one should use a small sample in the capillary and the sample should be firmly packed.
