The 2L Vacuum Rotary Evaporator Distillation Unit is mainly used for the continuous distillation of a large number of volatile solvents under reduced pressure, especially for the concentration of the extract liquor and the distillation of the receiving liquid at the time of chromatographic separation. It is one of basic instrument to separate and purify the reaction product used by chemical industry, pharmaceutical industry, university and scientific research laboratories.

The combined effect lowers the boiling point of the component liquids in the system, greatly aiding in the process. The centrifugal effect of the rotary movement creates friction, resulting in a thin layer of solvent being spread over the surface.

This helps isolate various products from samples, and is a preferred method of chemical extraction. As with all chemical equipment, make sure that the user takes proper safety precautions. Handle the equipment with care, and follow all instructions, guidelines, and local laws. Feel free to browse our FAQ to learn more about safety and our equipment warranty.

1. Ask: What’s the design basis of main engine and water bath kettle rising and falling? 
Answer: It’s mainly from the consideration of convenience, safe and economical. Generally, small-size rotary evaporators below 5L use main engine rising and falling and evaporators which are above 5L use water bath kettle rising and falling. 

2. Ask:How about the anti-explosion ability of R series Rotary Evaporator? 
Answer:Our company’s Rotary Evaporator adopt alternating current dynamo, stepless speed regulating (or frequency control), no electric brush and no spark in operation. Water bath kettle which goes with the evaporator adopts nitrogen-sealed relay control, silicon-controlled contactless switch and vacuum switch. Manual control switch adopt twice circuit control which make electric current less than 3mA and has favorable anti-explosion feature. 

Ask:How to select all kinds of rotary evaporator? 
Answer: As for structure, our R series products all have excellent corrosion resistance ability and leakproofness ability. According to the solvent volume, 2L, 3L, 5L’s machine is fit for lab and sample test; 5L, 10L, 20L’s machine is fit for medium experiment; 20L, 50L’s machine is fit for medium experiment and production, especially suitable for the extraction of metal ion-avoiding polluted material.

Ask: What’s the feature of rotary evaporator comparing to other evaporators? 
Answer:It has the advantage of small structure, efficient, easy to observe and no metal ion pollution. It is applicable for laboratory, production and valuable material extraction. Its leakproofness ability can compare favorably with foreign equipment while it remain improvement in appearance and humanization design.
