Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a demulsified heating centrifugal device. Background Art

[0002] Liquid-liquid extraction, also known as solvent extraction, is a method of transferring solutes from one solvent to another by taking advantage of the different solubility or partition coefficients of substances in two immiscible (or slightly soluble) solvents. This technology is widely used in the inspection and testing of chemistry, medicine, food, cosmetics, medical devices, etc. It is one of the most effective extraction and purification methods for sample pre-testing. For example, a centrifuge with application number "CN202321997700.3" aims to solve the technical problem that existing centrifuges are difficult to meet the extraction needs of multiple substances with large differences in the required centrifugal force.

[0003] In the actual inspection process, when performing liquid-liquid extraction on most samples, a very important operation is to shake the sample violently to ensure complete contact between the two phases. Complete mixing occurs in the separatory funnel, which helps the sample to be fully extracted from a solvent. However, during the extraction process, violent shaking often produces an emulsion at the interface of the two phases, i.e., emulsification, which makes the interface between the two phases unclear and the target substance cannot be accurately collected, resulting in inaccurate inspection data. Commonly used methods for eliminating emulsification mainly include static method, adding inorganic salts and other solvents to eliminate emulsification, heating or centrifugation. The static method takes too long, ranging from several hours to one day, and cannot guarantee the inspection efficiency. The method of adding other solvents has limitations. The centrifugal method can promote the separation of the two phases by using the different relative gravities of the two phases through the action of centrifugal force, but due to the special shape of the separatory funnel, it cannot be placed in a centrifugal device, thereby increasing the difficulty of centrifugation. In order to solve the above technical problems, the utility model provides the following solutions.

[0004] However, the centrifuges currently used in laboratories can only accommodate centrifuge tubes of up to 50 ml. However, during the extraction process, the amount of liquid is large and there is no way to pour it into the centrifuge tube for centrifugation, resulting in loss of target substances, inaccurate test data, and low method recovery rate, which has limitations.
