Precision Digital Melting Point Apparatus SO-MP

This is a compact instrument designed for accurate determinations 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 silicon oil bath consists of a plain cylindrical container of corning glass having capacity about 200 ml. It is having a teflon 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 immersin heater. The rate of heating of the bath can be precisely adjusted by the controller on the panel.
The tips of the capillaries fitted 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.
The operator can concentrate on the visual observation of the sample without looking to the thermometer, the readings obtained are very accurate.
  The range of the apparatus is from ambient up to 2500C, with readability 10C. The apparatus is supplied with 175 ml. Silicon oil for use up to 2500C 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.
