Description

Technical Field

[0001] This utility model belongs to the technical field of gel dispensing equipment, specifically, it relates to a multi-groove independent sealed gel dispensing comb with interlocking teeth. Background Technology

[0002] In biochemistry and molecular biology experiments, gel electrophoresis is a fundamental and important technique used to separate, identify, and purify biological macromolecules such as DNA, RNA, and proteins. The gel sample comb, as a key instrument in gel electrophoresis experiments, directly affects the accuracy and reliability of the experimental results.

[0003] Traditional gel loading combs have revealed numerous problems in practical use. On the one hand, when processing multiple different samples or grouping samples, conventional combs struggle to achieve flexible grouping operations and lack the ability to link the teeth together, leading to cumbersome experimental procedures and a high risk of sample confusion. On the other hand, during sample loading, the lack of an effective seal between the comb and the gel often results in sample leakage and diffusion, which not only interferes with experimental results and wastes samples but may also contaminate the experimental environment. Furthermore, traditional combs often have a relatively simple structural design, making them difficult to adapt to different specifications and types of gels, resulting in poor versatility. With the continuous development of biological experimental techniques, the requirements for the functional diversity, ease of operation, and accuracy of experimental results of gel loading combs are increasingly higher.
