      Precision Digital Melting Point Apparatus
      Product Code : 026
      Brand Name : LASIN
      Product Description

      This is a compact instrument designed for accurate determination of melting points of solid samples. The unit consists of a built-in magnetic stirrer, an electronic controller for adjusting the rate of heating of silicon oil bath, an ON/OFF switch, a pilot lamp, magnifier, a glare free illuminated background, a HIGH/LOW range selector switch and a digital temperature indicator with PT- 100 sensor. The outer body is made of grade 304 stainless steel. 

      The silicon oil bath consists of a plain cylindrical container of corning glass having capacity about 200 ml. It is having a ptfe cover with five holes. Three for holding the capillaries, one for the boiling point tube and one for the temperature sensor. Besides, it is fitted with a special type of oil immersion heater. The rate of heating of the bath can be precisely adjusted by the controller on the panel.

      The tips of the capillaries filled with sample powders can be kept suspended in the oil bath through the cover. The tips can be clearly observed through the magnifier on the illuminated background of the bath.

      A highly sensitive PT-100 sensor is fitted to the equipment so that the melting points can be correctly determined by varying the temperature of the bath. A 'STOP' button is fitted on the front which is to be pressed when the desired change is observed in the sample under test. The temperature reached at that stage is then held on the digital display. Heating can be started again by re- pushing the 'STOP' button. The operator can concentrate on the visual observation of the sample without looking to the thermometer as the readings obtained are very accurate.

      The range of the apparatus is about 2 deg. celcius above room temperature up to 300 deg. celcius, with readability up to 1 deg. celcius. The apparatus is supplied with 175 ml. Silicon oil for use up to 300 deg. celcius and a box of capillaries. It can also be used for determination of boiling points, flow points and molecular weight by Rast's method with special tubes, not supplied with the instrument.
