The Stuart SD162 Stirring Hotplate by Cole Parmer, has plate dimensions of 160mm by 160mm, with heating across the entire surface. Power is 0.7kW. A PTFE coated probe is supplied for insertion into the liquid to control sample temperature to within ±0.5°C accurately. Sample temperature and set temperature can both be viewed on a vacuum fluorescent display. By removing the probe, the surface plate temperature is shown instead, allowing versatility for other applications such as warming microscope slides or microarrays and specialist electronics.
Stirring is by powerful magnets and a motor, speed is adjustable between 200 to 1300 rpm, mixing volumes up to fifteen litres for single stirring operation only. The surface plate is made from Aluminium silicon alloy, providing excellent heat conduction and a robust surface which responds quickly to changes in temperature setting, the maximum temperature is 300°C. For safety, a flashing warning light turns on when the temperature exceeds 50°C. The independent safety circuit is triggered when the temperature increases 20ºC above the set temperature, cutting the heating, making unattended use possible. A corrosion-resistant coating protects the electronics.
The advanced microprocessor determines capacity and sample make up (e.g. oil or aqueous) as the hotplate heats the sample to the set temperature. Optimisation of the heating rate automatically occurs minimising overheating and set point time. When a set temperature is reached an audible alert sounds. The stirring action allows even heat distribution throughout the sample- providing enhanced heating uniformity.
Temperature and Stirring speed control are digitally operated by the push button dial setting knobs at the front of the stirrer hotplate, ensuring accurate repeatability when dealing with work involving multiple samples. Supplied complete PTFE probe and fitting for retort rod, 2 x 25mm PTFE coated stir bars and power cord.
