multi-function 20l digital condenser rotary evaporator for distillation
The R-1020A Rotary Evaporator adopts stepless speed regulation to make the glass rotating flask rotate at a constant speed. Materials can form a large area of uniform thin film on the wall of the flask. Then the rotating flask is heated evenly by the intelligent constant temperature water bath, and the material is evaporated rapidly under the vacuum condition. The solvent steam is recycled in the receiving flask after being cooled by the high efficiency glass condenser.
The R-1020A Rotary Evaporator has made new breakthrough based on inheriting the excellent performance of RE-2002 series, mainly as follows:
1. The vacuum pressure gauge can display the real-time vacuum, and the oil table have the anti-vibration performance.
2. Controlled by the check valve, the R-1010A Rotary Evaporator can realize the continuous feeding and be available for the vacuum switch under the working condition.
3. The latest integrated handwheel valves are adopted, having a better sealing performance and much easier operation.
4. The water bath is lifted and lowered electrically by adopting the deceleration booster motor, making the lifting and lowering process more stable.
5. The rotary evaporator has the function of over-temperature safety protection. When the actual temperature exceeds the 5 degrees centigrade of the setting temperature, the rotary evaporator will power off automatically to stop heating.
6. If the rotary evaporator powers off suddenly during the working, it will stop heating automatically when turning on the power again.

Details and Advantages:
1. The vacuum gauge is designed specially, with a high precision and good quality.
2. Main and auxiliary condensers are adopted, with the special double reflux serpentine condenser coils inside, increasing the cooling area and promoting the cooling efficiency.
3. Both the temperature and the rotating speed can be displayed through LCD screen, which makes it easy to operate.
4. Special flange connection makes it easy to disassemble, having a high fastening strength.
1. circulating water vacuum pump to offer a vacuum environment for reduced pressure distillation, they are widely used for vacuum filtration, vacuum evaporation, vacuum degassing, etc.
2. GDSZ series high and low temperature circulating pump to quickly cooling or warming, the circulating pump is an efficient equipment for quick temperature adjustment.
3. DLSB series low temperature cooling liquid circulating pump to conduct chemical reaction and medicine storage which requires low temperature environment.
Q: What’s the core technology of ethanol evaporator?
Answer: The key is system’s gas tightness, that is whether system can keep high vacuum degree under all sorts of solvent’s corrosion and movement state. Henan Lanphan’ s R series instrument, which is sealed by composite material four fluorine rubber and glass, can stand all sorts of solvent, has reliable gas tightness and can maintain a high vacuum degree above -0.096MPa.
Q: What factor decides the working efficiency of low temperature evaporator?
For same type equipment, mainly includes: steam temperature, vacuum degree and cooling water temperature. Restricted by some material’s thermolability, the steam temperature may have certain limitation when working, so high vacuum degree and low cooling water temperature are two main factors for efficiency improving (can select cryopump to lower the temperature)
Q: What’s the operating principle of ethanol evaporator?
Under the condition of negative pressure, evaporating flask rotating in the thermostat water bath, which makes solution form a thin film in bottle wall, so as to increase the evaporation area. Evaporating efficiently under low temperature, then condensate recycling through condenser pipe and concentrate to isolate the material to reach experiment requirements.
