The Rotary Evaporator is used for systematically removal of solvents from samples by using evaporation procedure in chemical laboratories. The working principle of rotary evaporator is that upon decreasing the pressure, the boiling point of liquids lowers which results the solvent to convert into vapour at lower temperatures when compared to boiling in standard atmosphere. Molecular cooking for the preparation of distillates and extracts can also be done by this device. After thoroughly studying the device and its functions we have designed the parts of rotary evaporator and assembled using SOLIDWORKS software. In this we have taken vapour duct, rotary mechanism assembly and bench for static analysis using SOLIDWORKS. The maximum static stress and static strain, minimum static stress and static strain of vapour duct, rotary mechanism assembly and bench are analyzed.The Rotary Evaporator is used for systematically removal of solvents from samples by using evaporation procedure in chemical laboratories.
