Background
Established in 1796, A. KRÜSS (or A. Kruess) Optronic has been producing
high-precision optical measuring instruments for more than 200 years. In a
nationwide competition held in 2005 the company won an award to become one of
Germany's "Top 100" innovative medium-sized companies. As part of our heritage
we not only consider it a social obligation to train apprentices in both the
technical and commercial sectors but also an essential factor in our long-term
innovation process.
M5000 Fully Automatic Melting Point Meter from A. Krüss Optronic
The fully
automatic M5000 melting point meter from A. Krüss Optronic in Hamburg
can automatically measure melting points precisely and repeatably. M5000
melting point meter is an ideal solution for applications in which multiple
samples in powder form with melting points between 25°C and 400°C have
to be examined in continuous laboratory operation with little time and staff
involvement.

Determination of Melting Points
The determination of melting points is one of the basic tasks in
chemical-physical analysis. The melting temperature is a
characteristic property of substances, by means of which the type and composition
of a substance or compound can be determined definitively in
many cases. With traditional measurement systems, the sample is heated in a
controlled way and determination of the melting temperature is carried out by
means of
observation with a magnifying glass or under a microscope. As the process
can only be carried out once with each sample, the laboratory staff
have to remain with and observe the equipment during the whole
measurement process. The assessment of the melting point and thus the
determination of the melting temperature is therefore carried out subjectively,
with the result
that different laboratory staff arrive at different
results. If a laboratory assistant misses the start of the melting, because
he or she is
distracted by their surroundings, the sample is spoilt.
M5000 Determines Melting Point Digitally
The M5000
determines the melting point digitally, without human
involvement. The laboratory assistant only needs to fill the sample into the
measuring capillary tube, insert this into the meter and start the measurement.
Within a few minutes, the M5000
runs through the temperature range until
the melting point is identified and signals that the measurement
is complete by sounding an alarm. Starting from room temperature,
a temperature of 300° C is reached in under four minutes,
the final temperature of 400°C after 7.5 minutes. The results of the measurement
can immediately be read on the clear digital display with a degree of accuracy
of
0.1°C and, if required, can be documented by means of an external printer,
which
can be connected directly to the meter.
Thanks to the integrated cooling fan, the M5000
is soon ready for
the next measurement. Accuracy of measurement and repeatability
of the results hold up to any comparison. Up to 200°C, the M5000
measures
to an accuracy of 0.2°C, above that to 0.5°C. The measurement values
can be repeated
over the whole temperature range with an accuracy of 0.2°C. Thanks to the
digital control, it has been possible to keep the operating parts of the M5000
as simple as possible. The membrane keypad, which is easy to clean, consists
of only four keys, two of which are used to select functions from a menu,
the third starts the measuring program and the fourth prints out the
results via the RS232 serial interface.
The Ease of Use of M5000 Fully Automatic Melting Point Meter
The elegant table-top meter, which is about the size of a telephone, is
supplied complete with a protective cover and 100 small melting point
tubes. It is particularly suitable wherever samples have to be analyzed and
recorded
without involving staff too much or taking up too much time, for example for
monitoring goods received, for approval inspections on
material batches for production, or quality assurance by means of
samples taken regularly from continuous production,
where results are needed without having to wait for them from the laboratory.
Since
it is so easy to use, the M5000
does not have to be operated by
trained laboratory staff, but can also be used by production staff who
have been instructed appropriately.
M5000 Meeting Regulations for Use in Drug Manufacturing
The M5000
meets the regulations
of the GLP, FDA and Pharmacopoea Eruopaea for use in the
manufacture of drugs. The M5000
is typically used in
the chemical industry, such as in the manufacture of plastic and paints,
in food production and monitoring, in pharmacology, and
also in forensics, where the purity of substances can be
determined by its melting behavior.
