Bumping and foaming are problems that commonly arise during evaporation and can lead to sample loss and contamination. As Jim Dawson, president of Heidolph North America (Elk Grove Village, IL), explains, the primary culprits are applying "too much heat, too much rotational speed, or too much vacuum" to a particular application.
2019-1-7 · A vacuum pump lowers a solvents boiling point by reducing pressure within the rotary evaporator. The water bath is deployed at 30-40 degrees with an ethanol vapor temperature 15-20 degrees C. Lower water bath temperatures prevent thermal decomposition.

Rotary Evaporator. The list of possibilities is endless. The PolyScience Rotary Evaporation System provides virtually unlimited possibilities to evaporate, distill, separate and purify liquids. You can now easily concentrate, capture and infuse flavors in your own kitchen.
Principle of rotary evaporator - Lab Instrument Manufacturer. 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 .
A rotary evaporator also has a vacuum system which is used to reduce the pressure inside the evaporator system. The sample is heated by the use of a heated fluid bath; water is the most common fluid which is used.
The rotary evaporator can seal and reduce pressure to 400-600 MMHG. The solvent in the evaporation flask is heated with a heating bath. The heating temperature can be close to the boiling point of the solvent, at the same time, rotating the evaporation flask, the rotating speed could keep at 50-160rpm/min, make the solvent being thin film, increase evaporation area.
Hawach rotary evaporator uses a motor to drive the distillation bottle to rotate. Because the distiller is constantly rotating, zeolite can be added without bumping. +86-29-89284429
