Microcontroller Visual Melting Point Apparatus Model 3935 with Graphical LCD display and colored TFT screen and high resolution camera. It is designed for accurate measurement of melting points and for checking the melting range of the solid samples. The apparatus consists of a silicon oil bath of about 200 ml capacity, covered with a Teflon cover with 5 holes, fitted with a special type of oil immersion heater and having three holes for holding the capillaries, one for boiling point tube and one for the thermometer.

The plateau temperature and the heating ramp rates are fully programmable using ‘Plateau’/ ‘Ramp’. The plateau temperature allows the user to set a temperature to few degrees below the expected melting point temperature. Auto melting point apparatus will then heat to the programmed plateau temperature very rapidly. Once plateau temperature is reached the instrument will heat slowly from the plateau temperature until the powder melts on programmed ramp rate.

A high resolution camera detects the sample status. This makes it a user friendly instrument.
