Load your sample into a clean round bottom flask 2440 fitAttach the round bottom flask to the condenserIf need be use vacuum grease located next to the rotary evaporator to create a vacuum seal between he condenser and the round bottom flask.

Sep 30 2021nbsp018332Rotary Evaporation Working PrinciplesRotary evaporation works on the principle that reducing the pressure on the solvent results in the analytes within have a lower evaporation point than at atmospheric pressureRotary evaporation is used in both preparative and analytical organic chemistry and can assist users in fractionating liquidphase.

The purpose of using the rotary evaporatorWe use the rotary evaporator rotovap for two main purposes 1To concentrate nonvolatile components in a mixture for example concentrating the purest and freshest flavors from a blood orange by removing the water 2.

The Rotary Evaporator is a tool which puts the separable substance under vacuum and heats evenly through a spinning motion causing one component to evaporate and leaving theThe chiller is normally set to 20 176CIf you need to change this temperature for some reason do not set it below 15 176CTo change the temperature rotate the knob.

The Rotary Evaporator It is commonly taught in General Chemistry classes that the vapor pressure of a liquid or solid varies directly with temperature ithe higher the temperature of a substance the higher itsYou need not set the rotation speed of the flask at maximum however you must rotate the flask to prevent bumping at reduced.
