Selecting a Suitable Vacuum Pump for Your Rotary

2019-4-4 · 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 merane 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.

Rotary Evaporator Ethanol Extraction - Coldfinger

2019-10-11 · For ethanol, the recommended vapor temp is 15-20 degrees C. Improper temperature configuration causes air within the rotary evaporator to saturate with the solvent. This is a leading cause of solvent loss. Maximizing solvent recovery requires an evaporator with a high degree of vacuum control and integrity within the air seals and gaskets
