China Vacuum Glass Rotary Evaporator Distillation

Description of rotary evaporator 50 liter

RE-5003 rotary evaporator's rotary bottle maximum capacity is 50L, receiving bottle's maximum capacity is 30L, rotate speed is 0-90r.p.m, motor power is 250W. RE-5003 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.

RE-5003 rotary evaporator has following features:

Rotating body is composed of a reliable three-phase asynchronous motor and a transducer control device; Double sealed by PTFE and fluorine rubber sealing ring to keep high vacuum degree, separate gas and liquid and maintain no backflow; Adopt main and vice efficient condenser, there has automatic switching device between vice condenser and receiving bottle. Below receiving bottle, equipping with tapping valve, which makes it convenient to recycle solvent and the recovery rate approach to 100%; Rotary bottle is connected by nut, that is easy to install and dismount; Continuously charging and recycling material; Vacuum system is equipped with vacuum meter, choose best working vacuum degree to low boiling point materials; Heating kettle is applicable for both water and oil, digital thermostat control and manual up and down, closed resistance wire heater, temperature control by K type transducer. Besides, heating groove can move left and right; Has the function of dry burning resistant protection and safe temperature loop; Smooth starting, can positive and negative inversion operate; Durable design, can choose plate bursting disk glass component as needed.

Rotary evaporator, also called rotavap or rotovap, is a commonly used lab instrument in chemistry laboratory, mainly used in 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. Because evaporator is vacuumized, to be distilled solvent's boiling point depressed. In general, ingredient which is distilled form sample is the target ingredient in chemical research, such as extracting some natural ingredient from organic synthesis sample. Rotary evaporator mostly is used for isolating low-boiling ingredient, such as hexane, ethyl acetate, that presenting liquid state under indoor temperature and normal pressure. Besides, it can dislodge some ingredient in sample by standard operation.

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.
Workshop

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 Electric Distillation Apparatus ?

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 Electric Distillation Apparatus ?

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.
