Abstract

The invention relates to the technical field of chemical experiment equipment, in particular to a rotary evaporator and in particular to a rotary evaporator capable of accurately achieving quantification of a concentrated liquid. According to the rotary evaporator capable of accurately achieving quantification of the concentrated liquid, a distillation bottle is improved into a structure that a liquid discharge hole is formed in the bottom, so that a concentrated liquid can be discharged on premise that the distillation bottle is not detached and the negative pressure inside a distillation system is not greatly affected; meanwhile, due to a metering tube with scales in the position of the liquid discharge hole, variations of quantities of the concentrated liquid can be visibly observed, distillation can be immediately stopped when the quantity of the concentrated liquid meets a designed accurate quantity, the precisely quantified concentrated liquid can be accurately discharged, indexes such as reaction yield can be tested, unification of detection standards can be achieved, properties of different concentrated liquids of same yield and properties of a same sample of different concentration degrees can be studied and compared.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a rotary evaporator, in particular to a rotary evaporator capable of accurately quantifying concentrated liquid. Background technique [0002] Rotary evaporator is an extraction experimental equipment for vacuum distillation and concentration of materials. It is widely used in experiments such as large-scale concentration, drying, extraction and recovery of samples, especially for rapid distillation of large amounts of solvents. Existing rotary evaporators are usually composed of vacuum pumping devices, heating devices, condensing devices, rotating devices and other components. The principle of rotary evaporators is mainly controlled by electronic equipment, so that the flask rotates at a constant speed at the most suitable speed to form a thin film of solvent , increase the evaporation area, and use a vacuum pump to make the evaporation flask in a negative ...
