Falling film evaporator working principle
Rotary Evaporators A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporation is most often and conveniently applied to separate "low boiling" solvents such a n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure. Auto 3L Rotary Evaporator Rotary evaporator is mainly used in pharmaceutical, chemical and bio-pharmaceutical industry concentration, crystallization, drying, separation and solvent recovery. The principle is under vacuum conditions, constant temperature heating, the rotating bottle constant speed rotation, a large area of the material in the sidewall formation film, efficient and evaporated.

Auto 3L Rotary Evaporator - Rotary evaporator with …
• Long life graphite impregnated PTFE vacuum seal • Efficient flask and vapour tube ejection system Rotary evaporators are distillation units that incorporate an efficient condenser with a rotary flask system. As the flask containing the solvent is rotated it continually transfers a thin layer of liquid over the entire inner surface. The liquid to be processed in the rotary evaporator is either charged batch wise by gravity, by a pump or sucked-in by vacuum into the evaporation flask. During the evaporation process further feed can be added by means of a pump, gravity or by the operating vacuum through the PTFE-hose passing the rotating shaft and ending in the spherical vessel.

How to use a Rotary Evaporator
9. Make sure the vacuum pump located next to the rotary evaporator is connected to the condenser. Make sure the release valve at the top of the condenser is turned to the closed position. 10. Turn on the vacuum. The gauge on the vacuum pump should read 27 in Hg if the system is not leaking. 11. The main components of a rotary evaporator. 1.A motor unit that rotates the evaporation flask or vial containing the user’s sample. 2.A vapor duct that is the axis for sample rotation, and is a vacuum-tight conduit for the vapor being drawn off the sample. 3.A vacuum system, to substantially reduce the pressure within the evaporator system.

Rotary Evaporators - Across International
Remember, the working principle of falling film evaporators is that the internal environment is operating under a vacuum, thereby lowering the boiling points of solvents like ethanol. As you may imagine, using a vacuum in this manner means that the heat energy expenditure is demonstrably lower (since you don’t have to heat the liquid solvent nearly as much). The rotary evaporator principle is the most universal method, as it is an efficient, last and gentle way to separate liquids. The rotating flask continuously covers a large surface area with a thin film due to Rotary motion, which is ideal for rapid heat transfer.
