The rotary evaporator rotates to form a film for high efficiency evaporation under the condition of negative pressure through constant temperature heating.The solvent was recovered by condensing tube to achieve the effect of separation and purification.Rotary evaporators are used in a wide range of applications, from laboratory to factory to kitchens.
The components of the rotary evaporator mainly include a S-shape condenser, an evaporation bottle, a collection bottle, a motor, a bath, etc., and the evaporation bottle is connected to the decompression pump through a highly refluxing serpentine condenser, and the other opening of the reflux condenser is connected to the collection bottle. It is used to receive the evaporated organic solvent.The transfer solvent can be removed from the distilling flask by the three-way piston between the condensing pipe and the vacuum pump. When the system is communicated with the vacuum pump, the system should be in a reduced pressure state.
When using, the distillation flask should be decompressed before starting the motor. At the end, the distillation flask should be stopped and then connected to the atmosphere to prevent it from falling off in rotation. In general, the basic principle of rotary distillation is vacuum distillation.
What is the application range of rotary evaporator?
Rotary evaporator is mainly used for continuous distillation of a large number of volatile solvents under reduced pressure conditions.In particular, the concentration of the extract and the distillation of the receiving liquid in the chromatographic separation can separate and purify the reaction product. The application of rotary evaporator is mainly in the scientific research and production process of pharmaceutical, chemical, biological products and other industries. Its functions are evaporation, concentration, crystallization, drying, separation and solvent recovery. The principle of constant temperature heating film evaporation under vacuum negative pressure condition was developed. Customers can choose different models according to different needs.
Rotary evaporators are used in teaching experiments in the laboratory. During the experiment, when the evaporation bottle was placed on the table, it was not easy to roll, not easy to break, and the school’s experimental expenses were reduced.
In recent years, the application of rotary evaporator has been extended to the cooking industry.Molecular cooking is a science that applies the principles of chemistry and physics to cooking.To some extent, molecular cooking has been promoted to be a proper term for describing innovative cooking styles. It is synonymous with cutting-edge technology and even psychology. The use of a rotary evaporator to non-heat evaporate liquid, thus retaining volatile aromatics that are easily lost by heating, is a perfect combination of modern culinary and experimental instruments.
Rotary evaporators are widely used and our customers come from all walks of life.Henan Lanphan science and technology will always strive to ensure the stability of product quality and advanced technology to meet the needs of all walks of life. email:[email protected]
