MICROPROCESSOR MELTING POINT APPARATUS (LIM-254)
MELTING POINT APPARATUS-(LIM-252 & LIM-253)
May 29, 2016
Melting Point Apparatus – 931 is designed for accurate measurement of melting points and for checking the melting range of the solid samples. The apparatus consists of silicon bath of about 200 ml capacity, covered with Teflon cover, fitted with a special type of oil immersion heater having three holes for holding the capillaries, one for boiling point tube and one for thermometer. The apparatus consists of in-built magnetic stirrer, with indicator for precisely adjusting the rate of heating of silicon oil-bath, an On/Off switch, a pilot lamp, with magnifier, a thermometer, a glare free background illuminator and a high/low range temperature selector switch.
