3. General description
The SMP50 is designed to automatically measure and record the melting temperatures of crystalline
samples held within capillary tubes. Up to three tubes can be accommodated in an illuminated
chamber within an aluminium block. The tubes are monitored by a digital camera; the image of which
can be viewed on the instrument display during the melting process. The device is designed to be
independently operated using the colour touch screen allowing all operational and data management
functions to be performed without the need to attach an external computer or keyboard.
The temperature range of the device is ambient to 400°C and the heating rate is variable between
0.1°C and 20°C/minute. All of the instrument functions and menus are accessed using the colour
touch screen interface which allows fast and intuitive navigation throughout a melting point
