The Stuart SMP20 has a 0.1-degree resolution, variable ramp rate and hold key to record the exact melt temperature. Ideal for use in education. Two samples can be tested simultaneously. They are viewed via a magnifying lens with clear observation aided by built-in illumination. Extendible back feet allow the unit to be operated at the optimum viewing angle. Full access to the block aids cleaning. The simple to follow instructions are printed directly on the instrument for ease of use.
To operate, select a plateau temperature via the digital display and press “start”. The unit quickly heats up and remains at the selected plateau temperature until the user is ready to start the test. Insert the sample tubes and press “start”. The unit then heats at a fixed rate at a user-selected rate of between 1 and 10°C per minute. When the sample is seen to melt, note the temperature on display. Press “stop” to end heating and cool the block.
Sample tubes are made from Soda glass; these can be easily be broken into two and sealed with a Bunsen flame; each pack has 100 tubes and includes a tube holder. Melting point tube dimensions: length 100mm, overall diameter 1.9mm, inner diameter 1.3mm, wall thickness 0.3mm.
