The invention relates to a method for detecting the performance of a rotary evaporator instrument. A detected rotary evaporator is provided. the instrument performance detection comprises: detecting the rotation speed of a distillation bottle, wherein an error between the measured rotation speed and the set rotation speed does not exceed + / -4%; detecting the swing amount of the distillation bottle, wherein the swing amount does not exceed 2.0 mm; detecting the water temperature in a water bath of a water bath heating system, wherein an error between the measured temperature and the display temperature does not exceed + / -2.0 DEG C; and detecting the vacuum degree of a vacuum pumping system is detected, wherein an error between the measured vacuum degree and the display vacuum degree does not exceed + / -5 kPa. The performance of the rotary evaporator instrument is detected, the reduced pressure distillation test process of the rotary evaporator that meets the detection requirements can beaccurately controlled, the use accuracy is improved, and the accuracy of the test result is ensured; a user can Fully understand the performance indexes of the instrument, and an important guaranteeis provided for accurate control in use and production quality control of the instrument; and the method is suitable for different models and specifications of rotary evaporators, and is good in versatility.
Description
technical field [0001] The invention belongs to the technical field of general physical or chemical methods or devices, and in particular relates to a method for detecting the performance of a rotary evaporator. Background technique [0002] Rotary evaporator is a common laboratory equipment, which is mainly used for continuous distillation of a large amount of volatile solvents under reduced pressure, and is widely used in pharmaceutical, biological, chemical, chemical and other fields. [0003] The working principle of the rotary evaporator is to make the distillation bottle in a negative pressure state through a vacuum pump. The lower part of the distillation bottle is placed in the water of the water bath and heated at a constant temperature. In the collection bottle at the lower part of the circulating condenser. In order to improve the evaporation efficiency, the rotating mechanism is usually used to make the distillation bottle rotate along its axis, and the distilla...
