The Stanford Research Systems OptiMelt provides a fast and accurate means of automatically determining the melting points and melting ranges of chemical substances. With microprocessor-controlled temperature ramping, a built-in digital camera, and a selling price that is half that of competing models, OptiMelt offers the best value of any commercially available melting point apparatus.
Automated Measurements
OptiMelt is specifically designed for unattended operation. It has a built-in digital camera that continuously captures real-time images of the samples, and it uses digital image processing to determine results. The melting points and melting ranges are prominently displayed on the front panel and automatically recorded into memory for later review.
OptiMelt has an intuitive front panel and is very easy to use. Simply select a start temperature, ramp rate, stop temperature, and hit start. Results can be easily seen from across the lab on the large LCD display.
Samples can be viewed on the front panel through a removable magnification lens. During a measurement, you can flag relevant events by pressing dedicated front-panel buttons. Up to six individual temperatures can be tagged for each sample. Interactive help is available for all functions and parameters of the instrument. Text and numerical entry keypads are built into the touch screen interface so that no external keyboard is required.

OptiMelt MPA100 Automated Melting Point System
The Stanford Research Systems 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. SRS 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 0.5ºC/min.
