Melting Point M-560 Operation Manual, Version G

4 Description of function

This section explains the basic principle of the Melting Point M-560 and provides a functional descrip­tion of the assemblies.

4.1 Melting Point

The Melting Point M-560 is an instrument for manual (visual) determination of melting point, melting
range, and boiling point at ambient temperatures +10 °C up to 400 °C. The melting point of three
samples can be determined at the same time. The boiling point can be determined for one sample.
Samples have to be observed through the lens.

The melting point capillary sits in a hollow of the metal block, which is heated electrically and
controlled by a temperature sensor. The heating block is capable of being maintained accurately at a
pre-defined temperature by the heating element, and of being heated at a defined rate.

4.2 Boiling Point

The boiling point is determined by the “Siwoloboff” method.

The Melting Point M-560 can be used to determine the boiling point of a small amount of liquid. The
heating block has one insert available for boiling point tubes (outside left). The moment of boiling is
determined visually.

The process for boiling point determination is analogous to that for determining a melting point:

• The start temperature is set 5 to 10 °C lower than the expected boiling point.

• The sample is put into the heating block as soon as the start temperature is reached.

• A delay time allows the equilibrium between oven temperature and sample temperature. During
this delay time some air bubbles escape from the boiling point capillary.

• Starting from the start temperature, the sample is heated at a temperature gradient of 1 °C/min.

• As the temperature rises, bubbles of gas rise slowly and regularly from the immersed end of the
boiling point capillary.

• The boiling point of the liquid has been reached when the flow of steam bubbles reaches a

frequency of 0.6 Hz [Hertz].

6.2 Melting point determination

NOTE

For exact melting point determination, use original capillaries from BUCHI only. If other capillaries are
used, the results may be inaccurate. Use the following items:

Product Order number

Melting point capillaries, 100 units 017808

Melting point capillaries, 1000 units 001759

Fig. 6.1: Melting point capillaries

6.2.1 Sample preparation

NOTE

Use only capillaries from BUCHI. They are precise and adequate for this kind of operation. Other
capillaries have other dimensions and wall thicknesses. Using others may result in results that are
incorrect.

Each sample has to be prepared.
The following methods to compact the samples are recommended:

• Using the Sample Loader M-569

• Knocking the capillaries on a hard surface.

NOTE

Sample preparation by letting the capillaries fall through a tube is not advised, because cross
contamination may occur.

Preparation of the samples:

• The samples being investigated must be fully dry, homogenous and in powdered form. Moist
samples must be dried first (the pharmacopoeias prescribe that the substance needs to be dried
in a vacuum for 24 hours over silica gel R). Coarse crystalline samples and non-homogeneous
samples are finely ground in a mortar.

• To fill the capillary tubes with the sample, the open ends of the tubes are pressed into the
substance. The substance is moved to the bottom of the tubes by repeatedly tapping the tubes
against a hard base.

• Enough substance must be filled into the glass capillary to form a compact column 4–6 mm in
height. (A height of 4–5 mm is recommended for precision measurements.) To ensure compa­rable results, it is important to fill all three capillary tubes to the same height and to compact the
substance well in the tubes using the Sample Loader M-569.

6.4 Calibration

NOTE

BUCHI recommends calibrating each new instrument after installation. Furthermore it is recom­mended that the instrument be recalibrated every year.

Two calibration modes are available: with BUCHI substances and user defined substances

6.4.1 Calibration principle

NOTE

The instrument is calibrated using melting point standards. The calibration is valid for boiling points

as well. The calibration procedure is recommended to be performed with the BUCHI calibration

substances, in the BUCHI calibration set mode.

Use the calibration set (11055018). This calibration set contains the melting point standards listed
below. Each standard is shipped with a certificate of analysis and an MSDS (material safety data
sheet).

The calibration set contains the following substances:

• 4-Nitrotoluene: approx. 52 °C

• Diphenyl acetic acid: approx. 148 °C

• Caffeine: approx. 237 °C

• Potassium nitrate: approx. 335 °C

From each substance, a minimum of 6 have to fulfill a standard deviation of less than +/- 0.2 °C.
Otherwise the instrument will not move on to the next substance. The maximum number of samples
for each substance to reach the deviation of +/- 0.2 °C is limited to 12 samples. The instrument auto­matically chooses the best 6 results from the determinations performed.
After a successful calibration is done, it may be checked using the verification set (11055019). Each
standard of the set contains a certificate of analysis and the MSDS.

The verification set contains the following substances:

• Benzil: approx. 94 °C

• p-Anisic acid: approx. 182 °C

• Phenolphthalein: approx. 261 °C

NOTE FOR USER MANAGEMENT

The calibration procedure can only be performed in the administrator level.
