The Memmert waterbaths are intended for the indirect tem-
pering of samples or materials. Water is meant to be used
as the tempering medium. A wide variety of samples are
tempered in a range from approx. 5°C above room temper-
ature to 100 °C. This can be done in suitable vessels such
as test tubes, Erlenmeyer flasks etc., or if the sample to be
tempered is suitable, in direct contact with the tempering
medium.
It is not possible to include all possible applications. Ap-
plication is at the operator’s discretion and under their re-
sponsibility.
