RE-501 5L Rotary Evaporator


  Product Description

RE-501 rotary evaporator’s maximum capacity is 5000ml, rotate speed is 5-120r.p.m, motor power is 40W. RE-501 rotary evaporator is the basic rotary evaporator series product of Henan Lanphan at present, it has manual up and down handle. The independent developed and elaborate designed machinery and glass components can accurately set the location of glass component. The digital display rotate speed and heating kettle’s temperature helps you optimally control all distillation process. New type fixation system greatly simplified the operation process of changing evaporating flask.

  rotary evaporator explained

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.

Rotary evaporator is also known as rotovap or rotavap, it is a common used lab instrument in chemical laboratory, mainly used for the continuous distillation of large amount easily volatilized solvents 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 room temperature and normal pressure. Besides, it can dislodge some ingredient in sample by standard operation.
