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 optimizes the heating rate to minimize overshoot and time to the set point. An audible alert sounds when the set temperature has been reached. 

Both set and the 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. Internal electronic components are protected against corrosion with a special coating.

Stirring action gives much better temperature uniformity within samples because the liquid is mixed effectively. Powerful magnets and motors give stirring speeds up to 1300 rpm and volumes up to 15 liters*. Stirring speed is set and displayed digitally so that 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 and 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.
