CB302
Hotplates, large capacity,
CB302 and SB302
Stylish and economical, general purpose stirrer hotplates designedwith
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.
