Key Features
Sophisticated stirrer hotplates offering digital control of
both temperature and stirring speed. Comes complete with
a detachable PTFE coated probe which when immersed in a
liquid sample can very accurately control its temperature to
within ±0.5°C even over a very long period of time.
As the hotplate heats the sample to the set temperature, the
advanced microprocessor automatically measures the rate of
temperature rise to judge the capacity and nature of samples
(e.g. oil or aqueous). It then optimises the heating rate to
minimise overshoot and time to set point. An audible alert
sounds when the set temperature has been reached.
Both set and actual temperature of the sample are displayed
simultaneously on a bright, easy to read vacuum fluorescent
display. For maximum security, an independent safety circuit
automatically sets to 20°C above the set temperature and shuts
off the heater if the temperature exceeds this. Therefore, the
hotplate is safe to leave on continuously, even unsupervised
e.g. overnight.
Stirring action gives much better temperature uniformity
within samples because the liquid is mixed effectively. Powerful
magnets and motor give stirring speeds up to 1300rpm and
volumes up to 15 litres*.
Stirring speed is set and displayed digitally so that exactly the
same speed can be used each time for reproducibility.
If the probe is unplugged, the temperature of the top plate can
be set on the display. This can be useful for applications where
accurate surface temperature is important such as warming
microscope slides, microarrays and specialist electronics.
There are two models to choose from:
Model CD162 has a glass ceramic top plate, which is chemically
resistant and gives very fast heat up times.
Model SD162 has an aluminum / silicon alloy top plate which
gives a very even plate temperature and quick response to
changing set temperature.
With fitting for retort rod and supplied complete with PTFE
coated probe and 2 x 25mm PTFE coated stirrer bars.
