R-1010A rotary evaporator is a newly designed rotary evaporator of our company, this series has 5L, 6L, 10L, 20L, 50L for selection.
R-1010A has new breakthroughs based on RE-1002 rotary evaporator:
1. Equip PTFE valve between condenser and receiving flask, easy operation and good sealing.
2. Check valve control, continuous charging, available for vacuum switch in working condition. The check valve also could be replaced with hand-operated valve to convenient for operation, better sealing performance.
3. The discharging valve is made from PTFE, consider of thermal expansion, other valves use glass valve element.
4. The water bath is electric lifting, lifting part use deceleration reinforcement motor, lifting process is more stable.
5. Use thicken rotary bottleneck to enhance loading bearing strength.
6. Use thicken rotary axis to enhance evaporation efficiency.
7. If the rotary evaporator sudden power lost during operation, when reconnect the power, it will automatic stop heating.

1. Special designed vacuum meter, high precision and good quality.
2. Main condenser and auxiliary condenser structure, double backflow snakelike condenser increased cooling area and promote cooling efficiency.
3. LCD screen display both temperature and rotating speed, operation is simple and convenient.
4. Flange connection make it easy to dismount, high fastening strength.
5. Rotary bottleneck and flange are thicken manufactured to improve loading bearing strength.
6. Equip with wrench to convenient for rotary flask dismantling.
7. The check valve between auxiliary condenser and receiving flask could be replaced with hand-operated valve to convenient for use, better sealing efficiency.
8. Use belt brake universal wheel, convenient and efficient.
1. Rotary vacuum evaporator matching use with 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. Rotary vacuum evaporator matching use with 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. Rotary vacuum evaporator matching use with DLSB series low temperature cooling liquid circulating pump to conduct chemical reaction and medicine storage which requires low temperature environment.
1. Ask: What’s the operating principle of most advanced rotary evaporator manufacturer?
Answer: 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.
2. Ask: What’s the core technology of most advanced rotary evaporator manufacturer?
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.
3. Ask: What factor decides the working efficiency of 10l rotary evaporator with chiller and vacuum?
Answer: 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)
4. Ask: What’s the difference between vertical and inclined condenser?
Answer: They have no difference essentially. Vertical condenser is gradually popular because of its small space usage and convenience for transportation and use. Most high-capacity instruments use vertical condenser.
5. Ask: What’s the design basis of AAA?
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.
