Determining Dropping Points
M
ettler Toledo’s dropping point
systems automatically determine
dropping and softening points of pitch,
asphalt, polymers, resins, waxes, paraffin
and binders. Dropping and softening
points are used mainly in quality control.
The Excellence line of dropping point
systems offers superior performance
and ergonomics, and is compliant with
ASTM, AOCS, DIN and ISO standards.
Standard compliant cups and measurement methods guarantee comparable
measurement results. Simultaneous analysis of two samples delivers the mean value
and the difference of the single results.

operation and provides clear information
Competitive
Ultrasonic
Cleaners
L
abotec has a new range of Scientech
Ultrasonic cleaners for effectively
cleaning micro-particles from a wide
scope of products. All tanks are manufactured from long-lasting, 304-stainless
steel and equipped with variable frequency
and power settings. They also have an
extremely good price to performance ratio.
The Scientech Ultrasonic cleaners are
especially useful for cleaning any precision
instrument part using their ultrasonic
vibrations. These cleaning units can be
used for emulsification, mixing and the
removal of oxidation from surfaces.
There is a choice of five different sizes
of cleaners, ranging from 2.5 to 25l. All
models operate with a temperature range
of ambient to a maximum of 80°C. They
units are all supplied with baskets and
lids as a
standard,
and all of
the units
above the
4l capacity
are fitted
with drain
taps for easy
maintenance. ⚛

for the user. Just one click is all that is
needed to start the measurement.
When completed, the instrument signals the end of the
measurement with an acoustic tone and displays the
measured temperatures.
One can also achieve high
throughput by simultaneously determining two samples in one run. The samples
are pre-melted and filled into the cups
sitting in the sample preparation tool,
which is preheated in a dry oven.
One can perform different
measurement
tasks rapidly
and efficiently
by working with
up to 60 stored methods.
Economic single-use cups
and heating without water or oil baths
eliminate the need for tedious cleaning. Visual camera observation and
digital image analysis guarantee that the
d
eterminations are reliable. The high
resolution colour videos recorded during
the measurement can be repeatedly
replayed on the instrument. This allows
one to check unexpected results by visually
reviewing measurements. ⚛
