Rotary Evaporator Solvent Table

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

Selecting a Suitable Vacuum Pump for Your Rotary Evaporator

Apr 04, 2019 Ideally, a pump used in a rotovap setup should be oilless and chemical-resistant to make sure it lasts as long as possible. The most commonly used pumps for this purpose are diaphragm (or membrane displacement) pumps. A variety of pumps (from left to right): an ME1 Diaphragm Pump, a VP Series Vacuum Pump, and a MVP 10 basic Vacuum pump.

Apr 05, 2016 Combination Vacuum Pumps, also known as Hybrid Vacuum Pumps, have both a Rotary Vane and Diaphragm pump together in the same vacuum pump. In a combination pump the diaphragm pump keeps the oil of the RV pump under negative pressure to reduce or eliminate vapors going through it and condensing in the oil. This design keeps the oil cleaner and ...
