Solvent evaporation device and solvent evaporation system

Abstract

The present invention relates to the field of solvent evaporation, and provides a solvent evaporation device. The solvent evaporation device comprises: a first solvent evaporation bottle; a second solvent evaporation bottle, which has a volume smaller than that of the first solvent evaporation bottle and can be jointed with the first solvent evaporation bottle from below; an evaporation bottle holding mechanism, which is used for holding the second solvent evaporation bottle therein; and a light guide component, which is arranged below the second solvent evaporation bottle and is configured toguide light to illuminate the solvent in the second solvent evaporation bottle from the bottom surface of the second solvent evaporation bottle so as to identify the liquid level of the solvent. Thelight guide component is configured as a light guide post, so that the second solvent evaporation bottle can be ejected out of the evaporation bottle holding mechanism. By means of the solvent evaporation device, the liquid level of the solvent in the second solvent evaporation bottle can be highlighted, the accuracy of liquid level detection is ensured, and meanwhile, the second solvent evaporation bottle is kept stable when the liquid level is detected through a simple structure. In addition, the invention also provides a solvent evaporation system.

Description

technical field [0001] The invention relates to the field of solvent evaporation, and mainly relates to a solvent evaporation device including two solvent evaporation bottles and a solvent evaporation system including the solvent evaporation device. Background technique [0002] Solvent evaporation device is a common laboratory equipment, mainly used for continuous distillation of volatile solvents under reduced pressure or heating conditions, used in chemistry, chemical industry, biomedicine and other fields. For example, in some accelerated solvent extraction applications, it is sometimes necessary to change the solvent before the analytes enter the gas chromatograph. In this case, the solvent needs to be completely removed from the original extract, and additional solvents can be introduced as needed. [0003] A solvent evaporation device usually includes an evaporation container, a suction device, a heating device, an air blowing device, an input pipeline, etc. The eva...

AI Technical Summary

Problems solved by technology

Usually, it is necessary to remove the first solvent evaporating bottle from the second solvent evaporating bottle, and then detect the remaining solvent in the second solvent evaporating bottle, but this is time-consuming and labor-intensive

[0008] Third, if a light source is used to illuminate the solvent in the second solvent evaporating bottle to observe its liquid level, on the one hand, the light source needs to provide greater light intensity to highlight the liquid level; on the other hand, even if a greater light intensity is provided, the second The position of the bottom of the solvent evaporating bottle is still not clearly visible, resulting in an inaccurate judgment of the remaining amount of solvent

On the other hand, it is not possible to easily replace the solvent evaporating bottles without ensuring their gas-tight connection
