Insert the capillary tube containing the sample into a slot behind the viewfinder of a melting point apparatus (Figure 6.11a). There are usually three slots in each apparatus, and multiple melting points can be taken simultaneously after gaining experience with the technique.

A melting-point apparatus is a scientific instrument used to determine the melting point of a substance. Some types of melting-point apparatuses include the Thiele tube , Fisher-Johns apparatus, Gallenkamp (Electronic) melting-point apparatus and …

Supplied with a pack of 100 capillary tubes, power supply and power cable. MP-250 Series Digital Melting Point Apparatus with rotating viewing head ensures each user can analyze samples clearly. Integral LED illumination and magnifying lens make viewing easy.

The melting point determined by the capillary method is the temperature at which the last solid particle of a compact column of a substance in a tube passes into the liquid phase.

What is the simple melting point apparatus? Answer: A simple melting point apparatus consists of a heating block or oil bath, a thermometer, and capillary tubes for holding the sample. The sample is heated gradually, and the melting point is observed visually or with a basic magnifying lens.

These pages describe two common methods for determining melting point using i a Meltemp apparatus and ii a Thiele tube set up. The temperature at which a solid melts and becomes a liquid is the melting point.

To determine the melting point of a sample with the help of the melting point apparatus, the sample is placed into multiple capillary tubes. The capillary tubes are then placed in the heating block. The sample is individually analysed and the average of the measurements is obtained to determine the exact melting point of the substance.

2024年9月14日 · Capillary Method: This traditional method involves filling a thin capillary tube with the sample and observing the melting point through a microscope or optical viewfinder. The user manually adjusts the heating rate and records the temperature at which the sample melts.

Kimble 34505-99 Glass USP Melting Point Capillary Tube with One Open End, 1.5-1.8mm OD, 90mm Length (Case of 20)

In this methodology, a thin glass capillary tube containing a compact column of the substance to be determined is introduced into a heated stand (liquid bath or metal block) in close proximity to a high accuracy thermometer.
