Melting Point Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-GLE-13233
Jlab Export is a leading Melting Point Apparatus Manufacturer,and suppliers in India
Melting Point Apparatus (code EL-GLE-13233) is a microprocessor-controlled instrument, model JL222, in which a miniature furnace heats a sample in a 1.4 mm capillary at an automatic ramp rate while you watch it through a magnifying glass. It reads from room temperature to 320 °C on an LCD with 0.1 °C resolution and plots a real-time melting curve. JLab builds this apparatus in Ambala, India.

Taking a Reading
Grind the dry sample fine, pack a little into the closed end of a capillary and slide it into the furnace. Set a starting temperature a few degrees below the expected melting point: the furnace reaches it quickly, taking under 3 minutes to climb from 50 °C to 320 °C, and then ramps on automatically. The sample is lit from front and rear, with adjustable light intensity, and seen enlarged through the magnifier. Press the MELT key the moment it melts; the reading is held, the furnace switches off, the cooling fan starts by itself and the melting temperature stays on the display. Cooling from 320 °C back to 50 °C takes under 5 minutes, ready for the next capillary.
What a Melting Point Tells You
A pure crystalline compound melts sharply over a narrow range. Impurities lower the melting point and spread it over a wider range, so the reading serves both to identify a compound and to judge its purity, for example after recrystallisation. The real-time curve gives a record of how the temperature rose up to the moment of melting.
