240V 300W CERAMIC heaters
These heaters have no thermostat and will rapidly bring solutions to a boil.
Their design allows them to fit right down into the solutions, eliminating problems hanging glass heaters over the tank edge. They won't break or shatter like glass heaters and heat up much faster.
Because they have no thermostat, they should be used when the solution requires boiling, or in conjunction with the Caswell thermostat.
These heaters have an Australian plug.
