All parts of the large rotary evaporator produced by the rotary evaporator manufacturer ZZKD are made of high temperature resistant borosilicate glass and Teflon for concentration, crystallization, separation and recovery of solvents. It has the characteristics of high evaporation efficiency, easy to use, low noise, reliable sealing and complete specifications. The specific models include 2L, 3L, 5L, 10L, 20L, 30L, 50L, etc. The working principle of the rotary evaporator is that under vacuum conditions, constant temperature heating makes the rotary bottle rotate at a constant speed, and the material forms a large area thin film on the bottle wall, which efficiently evaporates. The solvent evaporation is cooled by a high-efficiency glass condenser, and is recovered and collected in a bottle, which greatly improves the evaporation efficiency, and is particularly suitable for the concentration and purification of biological articles that are easily decomposed and denatured at high temperatures.

50L rotary evaporator is mainly laboratory commonly used equipment consisting of: motor, distillation flask, heating pot, condenser tube and other parts. The common configuration is shown in the following figure:

 

Features of large rotary evaporator:

1. Adopt international advanced EL airtight system, which can maintain high vacuum. Gas-liquid separation without reflux.

2. The main and auxiliary high-efficiency double condensers are adopted to ensure high recovery rate.

3. The electrical parts of explosion-proof rotary steam (electrical parts such as motor and speed control box) are all well-known domestic brands.

4. The rotating bottle is connected with nuts for easy loading and unloading.

5. There is a drain valve at the lower mouth of the collection bottle, which is very fast to recover the solvent.

6. The collection bottle is equipped with a vacuum check valve between the secondary condensers, which can continuously feed without affecting the evaporation vacuum when the liquid is discharged.

7. The vacuum system is equipped with a vacuum gauge, which can adjust the vacuum degree for low boiling point materials.

8. Electronic constant temperature control of water bath, and it can move up and down.

9, the structure is reasonable, pay attention to materials. The mechanical structure uses a large number of stainless steel and aluminum alloy parts. All glass parts use high temperature resistant borosilicate glass.
