Product Description  

R-1020A rotary evaporator adopts stepless speed function to make rotary flask rotates in constant speed, the 

material formed a large area of thin film, then the constant temperature water bath begin to uniform heat the rotary 

flask and the material is evaporated in high speed under vacuum condition, the solvent steam is refrigerated by 

efficient glass condenser and received to receiving flask.

R-1020A rotary evaporator is a newly designed rotary evaporator of our company, this series has 5L, 6L, 10L, 20L, 

50L for selection.

R-1020A has new breakthroughs based on RE-2002 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 teflon, 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

  1.  Ask: What’s the operating principle of rotary evaporator?
    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 Rotary 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. 

  3. Ask: What factor decides the working efficiency of Rotary Evaporator? 
    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 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. 

  6. 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. 

  7. 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.

  8. 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. 

  9. Ask: How to select vacuum pump for rotary evaporator? 
    Answer:We recommend water-circulating pump which can bear all sorts of solvent corrosion and can vacuumize to -0.095MPa(to satisfy using requirements). According to the solvent volume, we can offer various vacuum pump types.
