Setting up the heating bath
There are two different heating bath sizes for the Rotavapor R-300:
Heating Bath B-301 for flasks up to 1 L capacity, only suitable for the use of water
as heating fluid
Heating Bath B-305 for flasks up to 5 L capacity, suitable for the use of water and
oil as heating medium
Whichever size of heating bath is used, it is placed on the Heating Bath B-300 Base.
Depending on which size of heating bath is used, the heating bath base has to be
pushed in a different amount on the Rotavapor rail. With the smaller heating bath, the
B-301, the base is pushed in as far as it will go. With the larger heating bath, the
B-305, the heating bath base must not be pushed all the way in as otherwise the
Rotavapor lift will not be able to lower. A mechanical catch on the Heating Bath B-305
makes sure that the heating bath base is not pushed in too far.
