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.

5.6A: Overview of Rotary Evaporation - Chemistry LibreTexts

Apr 07, 2022 A rotary evaporator is essentially a reduced pressure distillation: a solution in a round bottomed flask is placed in the water bath of the apparatus (Figure 5.66a), and rotated while the system is partially evacuated (by a water aspirator or vacuum pump). The reduced pressure in the apparatus causes the solvent to boil at a lower temperature ...

Alternative to Rotovap Distillation - Rollitup

Jan 01, 2015 We then can distill the ethanol solution with a rotary evaporator with little to no heat at all, instead using vacuum. Which is why I believe it is possible to make a potent extract while preserving most if not more terpenes than many other forms of extractions widely used today. Last edited: Jan 4, 2015.

Why Rotary Evaporation Is More Efficient Than Standard Distillation

Why Rotary Evaporation Is More Efficient Than Standard Distillation

Jul 19, 2018 For an at-a-glance look, the factors that can help speed up evaporation are: Decreased pressure within the system. Increased temperature of the solvent. Rotation of the flask. While the first two factors can be changed with both rotary evaporation and standard distillation, only rotary evaporation has the added benefit of rotating the sample ...
