Rotary Evaporator Ventilation

APPENDIX 7 How to use the rotary evaporator.

12 Support the flask with your hand while you vent the rotary evaporator by turning the stopcock at the top of the rotary evaporatorIf your flask contains a fine solid you should vent slowly to prevent the solid from being sprayed around the flask or indeed the whole rotary evaporator13 Turn off the rotation and remove the flask.

BUCHI Rotavapor™ R300 Rotary Evaporator with ControllerThe R300 meets the highest expectations in convenience and versatilityIts modular design allows extension of the Rotavapor™ R300 to a fully integrated system where a central interface regulates each component.

A major advance in efficiency is achieved by using a rotary evaporator rotovapThis cuts the distillation time for eliminating ether from a couple of hours down to 20 minutes or soThe basic theory is that the apparatus works by vacuum distillation.

A rotary evaporator rotovap is a fast and effective method of removing solvent from a flaskA rotovap removes solvent by reducing the pressure within the flask using a vacuum rotating the sample to increase its effective surface area and heating the solutionThe steps outlined below address general laboratory safety concerns while operating a rotovap.

A rotary evaporator is a specially designed instrument for the evapora tion of solvent singlestage or straight distillation under vacuumThe evaporator consists of a heating bath with a rotating flask in which the liquid is distributed as a thin film over the hot wall surfaces and can evaporate easilyThe evaporation rate is regulated by.

A rotary evaporator is essential to distill dry recover or extract samples in many labsHowever any time solvents are being used especially under pressure and with heat significant safety concerns ariseEnsure the ventilation can be done safely and any vapors will be handled appropriately for safety and environmental concerns.

Load your sample into a clean round bottom flask 2440 fitAttach the round bottom flask to the condenserIf need be use vacuum grease located next to the rotary evaporator to create a vacuum seal between he condenser and the round bottom flask.

Removal of solvents by simple distillation is a tedious procedure complicated by setup and cleaning of the apparatusA major advance in efficiency is achieved by using a rotary evaporator rotovap.

After the evaporation is completed first turn off the speed switch and the temperature control switch press the lower pressure rod to raise the main unit then close the vacuum pump and open the vent valve above the condenser to make it open to the atmosphere remove the evaporation bottle and the evaporation process ends.
