Double Seal H540mm 1L Laboratory Rotary Evaporator

RE-2000E rotary evaporator is a newly designed new generation smart rotary evaporator, it adopts double row high-capacity blue backlight LCD as the human-computer interface, control part use high-performance single chip as main control chip, adopt special control program according to controlled member, beauty in appearance and stable in property. Besides, it has reserved updating connector, which can update software to meet client requirements.

The rotary evaporator can rotate to form a thin film, evaporate it effectively and then cool and recycle solvents when it is heated at a constant temperature under reduced pressure. It is especially suitable for the crystallization, separation, solvent recovery and other operations of heat sensitive materials. Some models can be applicable for the back-flow extraction.

Product Features

1.Variable frequency and adjustable speed. The imported frequency converter can ensure a stable and reliable operation.
2.The PTFE and rubber are adopted as a composite sealing, which can maintain a high vacuum degree.
3.The high-efficiency condensers can ensure a high recovery rate.
4.There is an automatic switching device between the auxiliary condenser and the receiving flask. The lower port of the receiving flask is fitted with a piston, convenient to recycle solvents. The continuous feeding and materials recovery can be realized without downtime.
5.There is a vacuum gauge in the vacuum system. The optimal working vacuum degree can be selected for materials with low boiling point.
6.The water bath is controlled digitally at a constant temperature and can be both lifted and lowered.
7.Reasonable structure and exquisite materials. The mechanical structure is mostly made of stainless steel and aluminum alloy. The glass components all adopt high borosilicate glass that is high temperature resistant. Sealed by rubbers, the easily damaged parts all conform to the new national standard, convenient for users to purchase and replace.

1. Chiller; 2. Vacuum Pump; 3. Water/Oil Bath

1. 1 year warranty service and all life maintenance, free change for non-human damaged parts within a year;
2. Change of artificially damaged parts within warranty service period charges according to purchase(process) price;
3. Continue providing excellent technical service beyond the warranty service period, and customer enjoy a privilege of buying fittings at a lower price;
4. Remote control technical consult, install DVD for free.
5. Technical engineers are available for oversea training.

Q: What’s the operating principle of a rotary evaporator?
Under the condition of negative pressure, the 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.

Q: What’s the core technology of a rotary evaporator?
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 a rotary 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)
