RE-5002 rotary evaporator Product introduction

RE-2002 rotary evaporator rotating bottle maximum capacity 20L, collection bottle capacity 10L, speed 0-140r.p.m, motor power 180W. It is mainly used for continuously distilling a large amount of volatile solvents under reduced pressure, especially for concentration of the extract and distillation of the receiving liquid during chromatographic separation, and the reaction product can be separated and purified. Under reduced pressure, when the solvent is distilled, the distillation flask is continuously rotated. The distillation flask is a pear-shaped or round-bottomed flask with a standard grinding port, connected to a vacuum pump through a highly refluxing serpentine condenser, and a reflux condenser. Another opening is connected to the receiving flask with the grinding port for receiving the evaporated organic solvent. There is a three-way piston between the condensing tube and the decompression pump. When the system is connected to the atmosphere, the distillation flask and the liquid-receiving flask can be removed from the transfer solvent. When the system is connected to the decompression pump, the system should be decompressed. status. When using, depressurize first, then start the motor to rotate the distillation flask; at the end, stop first, then pass the atmosphere to prevent the distillation flask from falling off during rotation. As a heat source for distillation, it is often equipped with a corresponding constant temperature water tank.

The R/RE Series Rotary Evaporator uses stepless speed regulation to rotate the glass rotating bottle at a constant speed. The material forms a large area of uniform film on the wall of the bottle, and then the rotating bottle is uniformly heated by a smart constant temperature water bath and evaporates at high speed under vacuum. The vapor is cooled by a high efficiency glass condenser and then recycled to the collection bottle. The R series is our new rotary evaporator with 1L, 2L, 3L, 5L, 10L, 20L, 50L, 100L models, and can produce explosion-proof rotary evaporator according to customer requirements.

RE-5002 rotary evaporator Product Specifications

Q:What is the core technology of the rotary evaporator?

A:It is the airtightness of the system, that is, whether the system can maintain a high vacuum under the action of various solvents. Rotary evaporator, sealed with rubber PTFE composite material and glass, can withstand various solvents, has a durable and reliable air tightness, and can maintain a high vacuum of -0.096MPa or more.

Q:What are the main factors affecting the efficiency of the rotary evaporator?

A:For the same specification machine, there are mainly: steam temperature, vacuum and cooling water temperature. Due to the heat resistance of some materials, it is impossible to increase the steam temperature indefinitely during work. Therefore, high vacuum and low cooling water temperature are the two main factors to improve efficiency (optional cryogenic pump can be used to reduce water temperature)
