Applies to all devices with heating.
WARNING
Risk of scalding
During heating, vapour bubbles can rise explosively under certain
conditions (boiling delay).
– Stir the sonication liquid occasionally during heating or switch
on the ultrasound.
Heated sonication liquid intensifies the effect of the ultrasound.
Experience has shown that the best results are obtained with a
temperature of 50 to 60°C. This can reduce the sonication time. At
higher working temperatures, the effect of the ultrasound
decreases again.
Ultrasound also heats the sonication liquid. During continuous
operation, the working temperature of the sonication liquid can rise
above the set value – particularly if the ultrasonic oscillating tank is
covered. Therefore, check the working temperature when process-
ing temperature-sensitive objects.
• Note the information on the optimum working temperature
from the agent manufacturer.
• Pre-heating during the degassing of the sonication liquid is
ideal. See chapter 5.7 Degassing sonication fluid .
• Before pre-heating, remove the basket or other accessories
from the ultrasonic oscillating tank. Cover the ultrasonic oscillat-
ing tank with the lid if available.
Information
The heater is equipped with overtemperature protection. If there is
no heating function, disconnect the device from the mains and
allow it to cool down to below 50 °C before putting it back into
operation.
Toggle switch (separate)
Switch on the heating using the toggle switch.
