[0002] Most filter papers are composed of cotton fibers, and different methods are used for different purposes. Since its material is a fiber product, its surface has countless small holes for liquid particles to pass through, while larger solid particles cannot pass through.
[0003] Filter paper is a common disposable item in the laboratory, and it is a consumable item. Therefore, the laboratory needs to stock a large amount of filter paper. The most important use of filter paper is to separate mixed liquid and solid substances. In addition, it is also used to prevent corrosion when placing it on the tray during the weighing of corrosive solids on the tray balance. In addition, due to its good moisture absorption performance, it is also used to dry some instruments related to concentration. In short, filter paper has a wide range of uses in the laboratory. When purchasing filter paper, in addition to the circular filter paper available on the market, it is usually a large sheet of filter paper. In order to ensure the accuracy of the experimental results, the large sheet of filter paper needs to be cut into a specific size. However, the existing filter paper cutting device cannot accurately and quickly cut filter paper into a specific size.
