Melting Point Tips and Guidelines

MELT TEMP II HEATING CURVES 

OPERATING INSTRUCTIONS - Plug the power cord in, turn the power switch on, and set the Power Control Knob to obtain the desired heating rate at the anticipated melting range. Use the heating rate charts below to select the correct voltage to obtain the desired heating rate at the melting range. Optimum heating rate for most samples is 1-2 degrees per minute at the meling point.
THERMOMETERS- The thermometer is manufactured expressly for use in the MEL-TEMP Capillary Melting Point Apparatus. Do not use a different thermometer.
The Power Control Knob controls the amount of heat reaching the sample and the rate at which the temperature increases.The graphs shown below show the results of having the knob set at various power levels.
