Background

A polymer solution or sol of a certain concentration can become a uniform and elastic semi-solid, i.e. gel, with a certain morphology under proper conditions. In industrial production, the polymer gel is often a large irregular concentrated gel in the preliminary step, and the polymer gel needs to be subjected to sterile preliminary cutting into strips or small blocks. Currently there is a lack of suitable tools to accomplish this.

Patent CN 217801851U provides a WB gel cutting device, which is composed of a base plate, a knife, a limiting component, a glass chopping board, etc. The cutting efficiency is guaranteed by cutting the gel through the clamping of the gel during cutting, and the gel is transferred through the glass chopping board, so that the problem that the gel is difficult to clamp is solved, and the experimental efficiency is improved. The device is only suitable for gel cutting by western blotting, namely is suitable for gel cutting with small size or soft and smooth texture, has single size, and cannot meet the production requirement.
