It is one of the scientific instruments utilized to measure the melting point of a substance. Some types of melting-point apparatuses are automatic melting-point equipment, the Thiele tube, Fisher-Johns equipment, and Electronic (Gallenkamp) melting-point equipment.
While the exterior designs of equipment can vary greatly, most apparatuses utilized a sample loaded into a sealed capillary, which is then placed in the equipment. The sample is then heated, either by an oil bath or a heating block or as the temperature rises, the sample is observed to measure when the phase change from solid to liquid happens. The operator of the device records the temperature range beginning with the primary phase-change temperature and ending with the completed phase-change temperature. At Kumar Instruments, the temperature range that is set on can then be averaged to gain the melting point of the sample being inspected.
Devices normally have a control panel that permits the final and starting temperatures, in addition to the temperature gradient (in units per minute), to be programmed. Some machines have various channels, which allows more than one sample to be tested at a time. The control panel might have buttons that permit the end and start of the melting point range to be recorded.
It is a glass instrument that is filled with oil that is heated by utilizing an open flame. The sample is settled in the opening in a capillary tube beside a mercury thermometer and permitted to be heated by the oil as it flows through the Thiele tube. By utilizing distinct oils, distinct temperature ranges can be reached and utilized to regulate melting points. This tube may also be utilized to find out boiling points, by utilizing a liquid sample instead of a solid sample.

This instrument with 4 digits, 7-Segment LED display is sketched for precise measurement of melting points and for examining the melting range of the solid samples. The device consists of a silicon bath, covered with Teflon with a special kind of oil immersion heater having three holes for the hold up the capillaries, one for the thermometer, and one for boiling point tube. The device involves an in-built magnetic stirrer, an electronic controller with an indicator for precisely adjust the rate of heating of silicon oil-bath, a glare-free background illuminator, a pilot lamp, digital temperature indicator with PT100 RTD sensor, an ON/OFF switch, a High/Low range temperature selector switch and with magnifier
The Start switch is utilized to initiate the measurement of the melting point. Customers can stop the measurement utilizing the Stop switch after the instrument reaches the melting point of the sample. The display will every time reveal the last temperature where the Stop switch is pressed in the final measurement. The clear switch is utilized to clear the display to zero.
