5.4 Determine melting points or melting ranges
5.4.1 Prepare samples
When you prepare the samples, pay attention to the rules listed below.
The amount of substance is the same across all capillaries. Slight differences in the amounts could cause
deviations in the measured melting point temperatures.
The melted substance still covers the hole for transmission light.
We recommend using capillaries from METTLER TOLEDO for compliance with standards.
5.4.1.1 Prepare samples of solid substances
In the following procedures, a sample height of 3mm is used. If you need to use a different height, you need to
adjust the procedure.
Prepare the substance
1 If your sample is moist, dry it in a desiccator.
2 If you have a coarse crystalline substances, grind it in an agate mortar to a fine powder.
Fill the melting point capillaries without the sample preparation tool
The substance and melting point capillaries are dry.
§
The substance is a fine powder.
1 Press the open end of the capillary into the substance.
2 To move the substance to the bottom of the melting point capillary, turn over
the melting point capillary and tap the bottom of the melting point capillary on
a hard surface.
The substance slides to the bottom of the capillary.
3 If the sample does not move to the capillary bottom, you can run the bottom
of the capillary along the ribbed part of tweezers or tamp it down using a
minimum amount of force with the tamping wire supplied.
4 To compact the substance tap the bottom of the melting point capillary
several times on a hard surface.
The substance is compacted.
5 Check the sample height with a ruler.
6 If the sample height is less than 3mm, repeat the steps above.
3mm of compacted substance fill the bottom of the melting point capillary.

5.5 Determine slip melting points (MP55 only)
5.5.1 Prepare samples
The height of the sample influences the slip melting point. For this reason the sample height needs to be
defined and constant. Most norms and standards require a height of 10mm.
To fill the boiling point outer capillary, you can either use the supplied syringe or a pipette. Both procedures are
described in this chapter.

6.2.2 Clean the insulation glass, the capillary guide and the transmitted light holes
To prevent false readings, the insulation glass should be checked regularly and cleaned as needed. Particles
and smudges on the insulation glass can block the light, cause bothersome spots in the pictures or cause false
readings.
Clean the insulation glass, if the light does not appear homogeneous and bright for all holes.
Occasionally, tiny particles can fall into the capillary guide or glass splitters of broken capillaries can remain
in the capillary guide. This debris can either result in black spots in the videos or prevent adequate light
exposure for the substances under investigation. In most cases, you can remove this debris.
The following chapters describe how to remove and reinstall the insulation glass and the capillary guide and
how to clean the parts.
