CAREDDI Rotary evaporators are developed according to BUCHI Rotavapor high-quality standards. They are widely used for solvent removal in the laboratory, distilling a large amount of volatile solvents under reduced pressure, especially for the concentration of the extract and the distillation of the receiving liquid during chromatographic separation, by this the reaction product can be separated and purified. During the evaporation process, rotary evaporators reduce the pressure within the system to lower the solvent boiling point, rotating the sample to increase the effective surface area, and heat up the solution. It is most often and conveniently applied to separate ‘low boiling’ solvents such a n-hexane or ethyl acetate from compounds .
Rotary evaporator system usually includes the vacuum pump, receiving flask, heating bath, condenser, and a trap ball. Users can also mix and match the rotary evaporator with different systems like water circulators, vacuum controller, recirculating chiller, solvent recovery units, and more, depending on their intended application purpose. The vacuum system used with rotary evaporators can be as simple as a water aspirator with a trap immersed in a cold bath (for non-toxic solvents), or as complex as a regulated mechanical vacuum pump with refrigerated trap.
A recirculating chiller or cooler ensures a consistent condenser temperature and eliminates seasonal temperature fluctuations that may occur when using tap water. A recirculating chiller provides an efficient, environmentally-friendly alternative to cooling with tap water, helping conserve water usage.
We have different modern models for the rotary evaporator with special characters:
- Speed controlled vacuum pump to be directly connected
- Digital displays for rotational speed and heating bath temperature allow for optimal control of all distilling processes.
Important Features of the Rotary evaporator
1) The vacuum pump is the source of reduced pressure in the system.
2) Spin speed and bath temperature control knobs.
3) Water bath
4) Bump guard.
5)Cold finger (Please do not use the rotavapor if the finger is not cold. There should be excess solid dry ice in the finger).
6)Vacuum release valve.
