Filter cartridge for cutting and filtering

Abstract

The invention relates to a filter cartridge for cutting and filtering which is used for filtering a solution after crude fat is extracted from a trichloromethane-methanol solution. The filter cartridge comprises a drum and a base cover; the drum comprises a drum tray and a first single-ring thread; the base cover comprises a second single-ring thread; the bottom of the base cover is hollow and is used for filtering the solution; and the upper part of the base cover is designed as a cutting edge and is used for cutting a filter paper. When the filter cartridge is used for filtering the crude fat solution, the filtering treatment can be quickly and effectively completed, the oxidization risk of the fat in the solution is reduced and the accuracy and reliability of the experiments, such as, subsequent fatty acid methyl esterification and other tests, can be promoted.

Description

technical field [0001] The invention belongs to the field of biotechnology, and is a filter device for extracting crude fat from muscle and gonad tissue of cephalopods, fish and other species to further carry out fatty acid detection experiments. Background technique [0002] Feeding ecology and reproductive input are important research contents when carrying out research on spawning strategies of cephalopods and fishes. The source of food intake, the accumulation of energy intake, and the allocation and input of reproductive energy are often the main contents of individual growth and reproduction of marine organisms, and different reproductive input strategies are often closely related to their reproductive strategies. In recent years, with the development of immunology and molecular biology techniques, biomarkers have gradually become the main research method for feeding ecology, especially for the study of marine biological populations. Among them, fatty acids have diffe...
