4 .3 Heating bath
The heating bath B-491 is multifunctional and can be used as a water bath or as an oil heating bath
up to 180 °C. The Heating Bath B-495 can be used as water bath up to 95 °C.
If you use a water bath, which is not suitable for the operation above 100 °C only water may be used
as heating medium (the use of any type of oils is not allowed). In case of an oil bath (e.g. B-491) only
specially approved heating bath liquids may be used. We advice against using silicone oils and low
molecular weight PEGs (Mol weight < 400 g/mol).
