Rotary Evaporator
People can expect this garment to be sturdy enough that they can move without having to worry about ripping seams.


1.Please let me know whether you have inventory wiped film in the US. What is the price and how fast we can get it. Thanks.

Now all wiped film molecular distillation are shipped from China. The delivery time of the MDS system is about 15-20 working days, and we will arrange the fastest transportation to you.

1L 3L 5L rotary evaporator is in stock and can be shipped within 1-3 days, 10L and above can be shipped within 1-5 days.

2.What are the advantages of your gear pumps?can I get more details on the gear pump?
Yes, we design with high precision gear pump for auto charging, while most other factories use peristaltic pump or centrifuge pump;---Peristaltic pumps and centrifugal pumps cannot be fed under high vacuum conditions. The system often encounters abnormal feeding during operation. It must be shut down and deflated to re-feed. High precision gear pump not only solve above problem to feed under high vacuum condition continuously; but also have two more advantages: A. pump head design with jacketed for heat preservation, which is much important for viscous material, such as essential oil; B. Constant feed/discharge won't affecting the vacuum of the entire system

Working principle of rotary evaporator is under the vacuum condition, constant temperature heating, evaporation bottle be rotary by constant speed, material forming a large area film at the wall of bottle, efficient evaporation. Solvent vapors through the efficient glass condenser cooling, recycling in the collection bottle, improve the efficiency of evaporation.


Rotary evaporator is mainly used in pharmaceutical, chemistry and bio-pharmaceuticals industries, for concentration, crystallization, drying, separation and solvent recovery. Especially suitable for the biological products concentration and purification which is easy to decompose deformation under high temperature.


1. Main condenser + Sub-condenser. Makes the condensation area & collection capacity to be greatly enhanced. High efficient cooling capacity, and less waste.

2. Double collection flask for continuously working without interruption.

3. High quality borosilicate glass 3.3 with excellent physical and chemical properties. PTFE sealing for excellent air tightness.

4. Explosion proof motor, UL certificated motor is available.

5. Integral explosion-proof control panel, convenient & safe operation.

6. Quality of detail, design of thermal insulation sleeve.

7. Anti-corrosion & Wearable sealing system.Sealing parts are flange with PTFE, Good oil seal & PTFE sealing & PTFE valves is anti-corrosion, no vacuum degree, no pollution to solvent received.
