Description

Bottle-rinsing workbench

Technical Field

The invention relates to the technical field of rinsing, in particular to a rinsing bottle workbench.

Background

The 60mL extraction collection bottle is mainly used for receiving the solution extracted by the accelerated solvent extractor, the accelerated solvent extractor uses common solvents to extract samples under heating and pressurizing conditions, the extraction efficiency is greatly improved, the solvent consumption is reduced, compared with Soxhlet extraction and microwave extraction, the accelerated solvent extraction only needs a very short time, the extraction requirement is met by using a small amount of solvents, and the accelerated solvent extraction is widely applied to the industries of environment, medicine, food, polymer and consumer goods.

The solvent extraction instrument is accelerated to perform solvent extraction under high temperature and high pressure:

the dissolving capacity of the analyte is improved, the viscosity of the solvent is reduced, and the molecules of the solvent can enter the sample matrix more easily; the ability of molecular motion is improved, so that the analytes are easier to break loose from the constraint of the matrix; improving the dispersion ability, making the analyte easier to diffuse into the solvent, increasing the pressure to make the solvent always keep liquid state high capacity, high flexibility and high efficiency in the extraction process, accelerating the extraction instrument to bring many benefits to the laboratory needing to automatically extract solid and semi-solid samples, improving the working efficiency,

collecting bottle solution shifts the back, and whether the rinse-off of bottle accords with the standard and has very big influence to the experiment, generally all is that the manual work adds a little fresh reagent, and the manual bottle that rotates rinses the bottle wall, and it is still feasible to do a small amount of samples like this, and when meetting a large amount of samples, manual rinse-off is done and will reduce work efficiency, causes the waste of time, consumes experimenter's plenty of time, does not have the device that is used for rinsing the collecting bottle specially at present.
