Instructions for use
1. Insert the thermometer.
2. Insert a 1.9mm sealed end capillary tube with sample into block.
3. Set the heating controller to 20°C/min.
4. Reduce to 10°C/min once the thermometer reaches 60% of the expected melting point.
5. Continue to reduce so heating rate is on 1°C/min when within 15°C of expected melt.
6. Observe the melt through the eyepiece, while recording the temperature on the thermometer.
7. Turn off to begin cooling. A brass plug can be used if more rapid cooling is required.

The 120 V Models are provided with a NEMA 5-15 plug. The 230 V Models are provided with a UK
3-pin and a “Schuko” 2-pin plug. Should the cable not be suitable for connecting to the power
supply, replace the plug with a suitable alternative.
THIS OPERATION SHOULD ONLY BE UNDERTAKEN BY A QUALIFIED ELECTRICIAN.
NOTE: Refer to the equipment rating plate to ensure that the plug and fusing are suitable for the
voltage and wattage stated.
The wires in the power cable (120 V) are colored as follows:
BLACK - HOT/LIVE
WHITE - NEUTRAL
GREEN - EARTH

The wires in the power cable (230 V) are colored as follows:
BROWN - HOT/LIVE
BLUE - NEUTRAL
GREEN/YELLOW - EARTH
IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN
Should the power cable need replacing, a cable of 1mm
an IEC320 plug should be used.
The appropriate power cable should be connected BEFORE connection to the power supply.

General Description
The Cole-Parmer Analog Melting Point Apparatus has been designed to be quick and easy to
operate – making it ideal for educational use. Supplied with a nonhazardous, spirit-filled mercury-free
thermometer. Using the manually adjustable heating rate, the block will rapidly heat samples up to
20°C per minute to the melt temperature and up to the maximum temperature of 250°C. An accurate
reading to within 1°C of the melt temperature can be achieved by using a slower heating rate of
between 1 and 10°C per minute. The sample is observed through the magnifying lens until the melt
occurs and the melt temperature read from the thermometer. Up to three samples can be viewed and
tested at any one time. Samples are illuminated by a bright white LED and viewed via a magnifying
lens. The magnifying lens can be detached for cleaning using the simple instructions printed on the
instrument.
Available separately are packs of capillary tubes that have been pre-sealed, a brass plug to speed
cooling time and spare thermometers. Please visit the Cole-Parmer website www.coleparmer.com for
further information.
Safety Advice
Users should be aware of the following safety advice:
❖ HIGH TEMPERATURES ARE DANGEROUS as they can cause serious burns to operators and
ignite combustible material.
❖ USE CARE AND WEAR PROTECTIVE GLOVES TO PROTECT HANDS.
❖ DO NOT use combustible substances near hot objects.
❖ NEVER lift or carry the instrument until it has been switched off and allowed to cool for at least 30
minutes. The thermometer markings will give guidance.
❖ The unit should be carried using both hands with the fingers under the side edges.
❖ NEVER move or carry the unit while still connected to the power supply.
❖ DO NOT position the unit such that it is difficult to disconnect it from the power by removing the
power cable from the socket at the back.
