DigiMelt is a modern, low cost, digital melting point
apparatus designed specifically for the student lab. Students
learn the visual detection capillary method of melting point
determination without the frustration of trying to control the
oven temperature. DigiMelt rapidly heats the oven to the
programmed start temperature, then ramps at the specified
rate. The student carefully observes the samples and records
the melting points with a touch of a button.
Digital Temperature Readout
DigiMelt incorporates a platinum resistance temperature
detector (RTD) instead of the usual mercury thermometer.
This means better accuracy on the readings, and no more
mercury cleanup from broken thermometers. The RTD is
encased inside the oven block making it virtually unbreakable.
Microprocessor Temperature Control
Some student instruments use a large knob that simply
throttles power to the oven without any sense of what the
target temperature is. DigiMelt uses an RTD for feedback, so
it “knows” the oven temperature. This means the students can
enter a start temperature, a ramp rate, and a stop temperature
and the microprocessor takes care of the rest. Furthermore, the
microprocessor can deliver variable amounts of power to the
oven, so it can quickly ramp to the starting temperature, then
perform the ramp as slowly as 0.5 ºC/min.
