stirrers & stirrer hotplates

主要特點(diǎn)：

Digital setting and control of both temperature and speed

Supplied complete with temperature probe for accurate control of liquid temperature

Advanced safety features:

- Flashing "Hot" warning light

- Independent safety circuit to protect against overheating

Choice of robust aluminium or chemically resistant ceramic tops

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 minimize 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. 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 motor give stirring speeds up to 1300 rpm 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.
