ISO Laboratory 1350*675*720mm 20 Liter Rotary Evaporator

RE-2002 rotary evaporator's rotary bottle maximum capacity is 20L, receiving bottle's maximum capacity is 10L, rotate speed is 0-140r.p.m, motor power is 180W. RE-2002 rotary evaporator(evaporating bottle volume>10L) is equipped with double condenser(main and vice condenser), which has better condensation effect and higher recovery rate. Because this rotary evaporator works under vacuum condition, and contact segment all adopt high temperature resistance material-high borosilicate glass and PTFE material, it is especially suitable for heat reactive material and material which is corrosive to stainless steel's concentration, crystallization, separation and solvent recovery.

The rotary evaporator has advantages of large contact area, high evaporation efficient, easy to handle, low noise, good sealing performance, complete in specifications and can manage easily foam material. It already has various specification products: 2L, 3L, 5L, 10L, 20L, 30L, 50L, 100L and so on, and the 100L rotary evaporator is an exclusive research and developed large-size rotary evaporator of our company, designed for the purpose of mass production need.

Packing List of Ideal Plant Essential Oil Distillation Equipment for Russian

1. rotary evaporator 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 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. ethanol 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 20l lab rotary evaporator crystallizer?
   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 ethanol 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.
