PERATION
Note
The solution temperature is approxi-
mately 25% cooler than the hot plate
surface temperature.
Note
If you allow the top plate to reach the
maximum temperature of 540°C while
preheating and then turn the control
down to a setpoint less than 200°C,
the temperature of the top will drop
rapidly to 200°C. Because of the natu-
ral cooling characteristics of ceramic,
the temperature of the top will drop
much more gradually after the top plate
temperature reaches 200°C.
Note
Boiling times are dependent on solu-
tion volume and the surface area of the
flask that is exposed to the hot plate.
For example, when heating the same
amount of solution in a 2L flask vs. a
1L flask, the solution will heat about
20% faster.

Heating Small Volumes
Preheating small volumes is not necessary as it may
cause the temperature to overshoot the desired set-
point.
Heating Metal Vessels and
Sand Baths
Because the advanced electronic control in the
Cimarec is capable of precisely regulating the top plate
temperature, metal vessels and sand baths may be
heated safely without the danger of the ceramic top
breaking. Use the lowest temperature setting possible
for applications to limit thermal stress to the ceramic
top. Using a metal vessel or sand bath may reduce
the life of the hot plate.
