Note the volume displacement caused by a sample (e.g. Erlenmeyer flask). Place your sample into
the empty bath. Only then fill in a sufficient amount of temperature control medium. Also note that
the level of the temperature control medium drops when you remove the sample. This may cause a
safety shutdown (low level protection) during an enabled thermoregulation. Therefore, switch off
the temperature control unit beforehand.
The entire area/volume of the “bath vessel Variostat” is not available (see picture above) in the
combination Variostat with “bath vessel Variostat”. For bath thermostats: Please note the size of the
bath opening (see data sheet from page 83 in section »Annex«.
