Description of  Thermal Rotary Evaporator

       RE-5000E rotary evaporator mainly used for continuous distillation of a large amount of volatile solvent under negative pressure. Especially for the concentration of extract liquor and distillation of receive liquid when chromatograph, it can isolate and purify reaction product. In reduced pressure condition, when solvent distillation, distillation flask in continuous rotation, the distillation flask is a pyriform or round-bottom flask who is connected to vacuum pump by a snakelike condenser pipe, the other open mouth of condenser pipe is connected to receiving flask to receive evaporated organic solvent. There is a three-way valve between condenser pipe and vacuum pump, when system connect to air, take down distillation flask and receiving flask to transfer solvent. Please reduce pressure first before rotate distillation flask; and please power off first before connect to air, to prevent the rotating distillation flask from falling off. Thermostatic water bath is the heat source for distillation. RE-5000E rotary evaporator mainly used in medicine, chemical engineering, biopharmacy industries for the concentration, crystallization, drying, separation and solvent recovery, especially suitable for concentrate and purify high temperature easily decomposed material.

Q: What’s the difference between vertical and inclined condenser?

A: 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.

Q: What factor decides the working efficiency of  Thermal Rotary Evaporator?

A: 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.

Q: How to select all kinds of  Thermal Rotary Evaporator?

A: 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 ionavoiding polluted material.
