Selecting a Suitable Vacuum Pump for Your Rotary Evaporator

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.

What Comprises a Complete Rotary Evaporator System?

Apr 18, 2018 The main purpose of a rotary evaporator is to increase the rate of evaporation of a solvent. It does this via three methods: The vacuum decreases the pressure in the system, lowering the boiling temperature of the solvent. The rotation increases the surface area of the solvent. The water bath heats the solvent.

Dimethyl Sulfoxide (DMSO) - Common Organic Chemistry

Dimethyl sulfoxide (DMSO) is a polar aprotic solvent that can dissolve a wide range of organic compounds. The high dissolving power of DMSO makes deuterated DMSO (DMSO-d6) a common solvent for NMR. One of the major drawbacks of DMSO is the difficulty of removal after a reaction. Its high boiling point (189 C) makes removal by rotovap very ...
