2) The flask is then clamped to the rotary evaporator and the equipment is turned on. The rotation is fixed to 100 rpm and keep constant throughout the experiment. 3) The temperature is set to 30⁰C. After the temperature is stabilized, the counting of time is started for fix time for 10 minutes. Then, the volume of the condensate is recorded.

Apr 18, 2020 Liposome properties such as size, polydispersity index (PDI), and charge were screened before and after ethanol evaporation. Only rotary evaporator (at constant speed and room temperature for 2 h) removed all of the ethanol content, with a final drug entrapment efficiency (EE) of 29.44 6.77%. This was higher than a conventional method.
