A vacuum rotary evaporator is used for quick single-stage distillations that treat the product gently. The process is based on the evaporation and condensation of solvents in a rotating evaporating flask. It is possible to work under a vacuum to ensure gentler treat-ment of the product and increase productive output.

Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

How does the rotary evaporator work? The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).

Mar 10, 2020 Both rotary evaporators and falling film evaporators are capable of distilling solvent at a relatively high throughput, but one shines through as the clear front runner. An average rotary evaporator will typically have a throughput rate of 5-10 L/hour depending on the size of the condenser and flask, vacuum level, and condensing efficiency.

Since its invention in 1950, the rotary evaporator has been a ubiquitous scientific tool for the use of solvent removal. The rotary evaporator enables the removal of solvent in a controlled manner under vacuum. Rotary Evaporators purge the solvents from the finished product and recovers them, making the oil exceptionally pure.

The fins are added to the bare-tube to increase the heat transfer capability. They act as heat collector that pick up heat from the surrounding air and conduct it to the refrigerant inside the tube hence improving the efficiency in cooling the air of the surrounding. They are best used in the air-cooling space where the temperature is around 34F.
