Description

Centrifuge tube external member capable of separating liquid

Technical Field

The utility model belongs to the technical field of the centrifuging tube, concretely relates to but centrifuge tube external member of liquid.

Background

The liquid-liquid extraction method is also called solvent extraction or extraction. A process for separating and extracting components of a liquid mixture with a solvent. The separation or extraction is achieved by adding to the liquid mixture a selected solvent which is immiscible (or slightly miscible) with the liquid mixture, taking advantage of the different solubility of its components in the solvent. A very important operation in liquid-liquid extraction is to shake the sample rapidly. This step ensures complete contact of the two phases and facilitates mass transfer. Emulsification often occurs in liquid-liquid extraction due to the intense vibration of the material, especially those samples that contain surfactants and fats. The collection of the substance to be tested must first be demulsified. Common techniques for demulsification are as follows: (1) adding salt; (2) using a heating-cooling extraction vessel; (3) the emulsion sample was filtered through a glass wool plug; (4) filtering the emulsion sample through a filter paper; (5) by centrifugation; (6) adding small amounts of different organic solvents; (7) waiting for a long time. The qualitative experiment can select (2), (3), (4), (5) and (7), the quantitative experiment can only select (5) and (7), and the selection (7) can use a common funnel with a piston at the neck to completely separate liquid from liquid, but sometimes the emulsification cannot disappear after standing for 2-3 days, the liquid-liquid separation cannot be realized, the working efficiency is low, and sometimes the substance to be detected is not as long as the substance to be detected is decomposed. However, option (5) currently has no suitable means for achieving complete liquid-liquid separation. In the prior art, after the centrifugal tube is taken out of the centrifuge, the centrifugal tube is directly poured for liquid separation, and because the opening of the centrifugal tube is large, when the upper layer liquid is poured, the lower layer liquid is easily poured out, so that the liquid separation precision is low; simultaneously because the liquid outlet of centrifuging tube does not have the drainage tube, when pouring liquid into the container that the opening is little, the easy edge leakage of liquid can not satisfy the demand of dividing liquid work.
