Key Features
Model Description
CP300 Hotplate, acid resistant, including control unit
Ordering Information
A heated glass ceramic plate mounted in a block of pure PTFE
creates a powerful hotplate which is almost impervious to
chemical attack, even by concentrated acids.
When boiling acid solutions the CP300 is unaffected by the fumes
and splashes which eventually destroy conventional hotplates.
The chemical inertness of the PTFE body and
ceramic top plate also means that much more
aggressive cleaning agents can be used. For
example, if all traces of metal must be removed,
this hotplate can be washed with concentrated
nitric acid!
The separate temperature controller is connected to
the hotplate via a 2 metre PTFE coated lead. This allows the
hotplate to be located in a fume cupboard and the controller
kept outside, well away from the corrosive environment.
The controller is also fitted with a “Hot” warning light that will
flash whenever the plate temperature of the hotplate is above
50°C and it will continue to operate when the hotplate is turned
off and connected to the electricity supply.
The hotplate has a large 200mm square heated area so is ideal
for heating either one large vessel or several smaller ones.
