1. The lowest possible temperature in a bath and the shortest cooling down time are dependent on: the
volume of liquid to be cooled, the type of liquid and its viscosity at the desired working temperature,
the heat conductivity of the liquid, the bath vessel and covering insulation, the heat created by any EK
immersed in the bath used to recirculate or stir the liquid.
The lowest temperatures possible for the EK45 and EK90 specified above were reached in a Dewar
vessel with a volume of 2 liters. Methylcyclohexane was used as the bath liquid and the bath was not
stirred.
2. The cooling capacity is reduced at ambient temperatures of > 25°C. 30°C max ambient for setpoints
>20°C for EK90, or >0°C for EK45. Example: Setpoint 40°C, max ambient = 30°C.
3. 1 meter from EK.
4. Never bend the probe when it is cold.
5. Nominal values ±10%.
