Rotary evaporator De Qumica

Although this operation could, in principle, be performed by simple distillation, the fastest and most convenient method is the use of a rotary evaporator (rotovap) for distillation under reduced pressure. Basically, it consists of an electric motor, which causes the rotation of a tube attached to a ground glass-oint guide tube.

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).

Nov 11, 2021 Rotary evaporators exploit this pressure-boiling point dependency and operate at a lower pressure, meaning you can boil liquids at a reduced temperature and without oxygen. This is crucial for mixology, and allows for a gentler distillation and avoids oxidation. The rotary evaporator was first commercialised in 1957 by Bchi for use in ...

Rotary evaporation: Solvent is removed at reduced pressure by mechanically rotating a flask in a controlled temperature water bath. Condensed solvent is collected in a separate flask: Volatile compounds are typically lost. Recovery of less volatile material may be lower than expected due to entrainment of the analyte the solvent vapor.
