The operation methodology of a Rotary vacuum evaporator is depicted in Fig. 6.14. There is a general 20/40/60 rule. It states that the temperature of the water bath should be 60 C, causing a temperature of 40 C of the sample and the vapor evolved is thereafter condensed at 20 C. For lower temperature ranges, a 0/20/40 rule is applicable.
