  • Page 8 Genevac EZ-2 Series Personal Evaporator – User Manual Introduction Using the most advanced proven technology in evaporation science, the EZ-2 Series has been designed specifically for solvent removal in life science research, be that concentration of samples or complete drying. Genevac’s fifteen years of experience in vacuum engineering has resulted in the creation of a compact sample concentrator combining great performance, ease of use greater than a rotary evaporator and compatibility with all commonly used solvents and acids.
  • Page 9 Fig 2 - EZ-2 Control Panel Compared with a typical rotary evaporator, the EZ-2 Series can process many more samples per unit time. Simply select the solvent type and the maximum allowable sample temperature. Smart evaporation software in the EZ-2 Series does the rest for you; setting the vacuum conditions and gradient, whilst controlling the heater lamp and automatically stopping the run once the samples are dry.
