Stuart CB302 - Stirrer/Hotplate, Ceramic Plate, 1200W, 30x30cm, 230v

Stylish and economical, general purpose stirrer hotplates designed with safety as well as performance in mind. The “Hot” warning light will flash whenever the plate temperature is above 50°C and will operate even when the hotplate is turned off and connected to the mains. Powerful magnets and motor give stirring speed up to 1500rpm and volumes up to 15 litres.

Model CB302 has a glass ceramic top that has excellent chemical and temperature resistance. The chemical properties make the surface very easy to keep clean and the thermal properties allow very high plate temperatures while ensuring the edges stay cooler, reducing the chance of accidental burns. 

Model SB302 has a robust aluminium/silicon alloy top plate. The very good heat transmission of this material gives rapid heating and ensures even temperature distribution across the whole of the plate. 

With fitting for retort rod and supplied complete with 2 x 25mm PTFE coated stir bars.

Heating

Models SB300, SB302, SB500, CB300, CB302, CB500:

The knob labelled “Heat” on the front panel controls the heat output and hence the plate temperature.

The knob is graduated from 1 - 9. Increasing the value increases the heat output.

Turn the hotplate control knob clockwise to the desired setting. The amber load indicator light will illuminate and it will begin to cycle on and off when the desired temperature is reached and the hotplate begins to control.

Models SD300 and SD500:

When connected to the mains electricity supply the digital display will illuminate and show the word OFF.

Stirring

Models SB301, SB302, CB302 and CR302:

The knob labelled “Stir” on the front panel controls the stirrer speed. 

It is labelled with an arbitrary numeric scale, 1 - 9 and turning the knob to a higher setting increases stirrer speed.

When the stirrer is switched on the amber pilot light illuminates.

Models CR300 and CR302:

The knob labelled “Heat” on the front panel controls the heat output and hence the plate temperature. When the heat is switched on the amber pilot light illuminates.

The knob is graduated from 1 - 9. Increasing the value increases the heat output.

In operation only the area defined by the pattern will become fully heated. The outer edges remain cooler for safety considerations. 

Vessels larger than the described area should not be used. Failure to observe this could give rise to overheating of the outer parts of the instrument.
