Description
Technical Field
[0001] The utility model relates to the technical field of experimental operation instruments, in particular to a device for extracting egg white and egg yolk for experiments. Background Art
[0002] In the laboratory, ELISA usually involves testing for certain pathogens in egg white or egg yolk. To extract the egg yolk, the eggshell is usually cracked open, the egg white is discarded, and the integrity of the vitelline membrane is guaranteed as much as possible. A graduated needle is then inserted directly through the vitelline membrane into the egg yolk to extract a certain amount of yolk. Manually cracking the egg and using a needle to extract a certain amount of egg yolk or egg white requires a lot of manpower and time for batch testing of breeding eggs, which is labor-intensive and inefficient. In addition, the egg is easily damaged during the cracking process, resulting in an inability to obtain a complete amount of egg yolk, wasting eggs, and even leading to sample shortages for important breeding eggs, which makes the test difficult. How to quickly and easily obtain the egg yolk or egg white, reduce the chance of egg damage, and save labor costs has become a problem that urgently needs to be solved. To this end, this application document provides a device for extracting egg white and egg yolk for experimental use. Utility Model Content
