ZZKD is established in 2009, a famous manufacturer of Lab equipment located in the central China.Rotary evaporator,Glass reactor,Short path distillation are our main products.Our products are exported to many countries in Asia, Europe, Africa and America,etc.

 
Rotary evaporator is mainly used for continuous distillation of volatile solvents under reduced pressure. It is suitable for reflux operation, rapid evaporation of large amounts of solvents, concentration of trace components and reaction processes requiring stirring, etc.It is widely used in pharmaceutical, biological, chemical, chemical and other fields.

At present, the use of the device mainly depends on the operating experience of the test personnel, and there is no relevant product standard to strictly control the technical parameters of the instrument.In actual operation, the solvent evaporation rate and the recovery rate of the collected sample in the vacuum distillation process are easily affected by factors such as water bath temperature, vacuum, condensation efficiency, and rotation speed, especially some chemical tests that require precise control, such as low concentrations or even trace amounts. The pretreatment of chemical sample content detection and the recrystallization purification of synthetic drugs with extremely high temperature sensitivity will have a great impact on the accuracy of the content detection results and the drug synthesis yield, etc. It is necessary to accurately control the technical performance indicators of the rotary evaporator.

Because the rotary evaporator is mainly used in the intermediate process of chemical testing, it is not a detection device that directly obtains data results, and is not controlled as a measuring instrument. Therefore, there is a lack of corresponding measurement technical specifications for evaluating the measurement performance of the equipment.In order to ensure the accurate control of the vacuum distillation process of the rotary evaporator, according to its working principle, the verification method of the equipment was studied.
