Hole puncher scraper is a tool used in chemical experiments to assist in the processing of soft materials. It is composed of a metal drill and a scraper. The drill is a hollow tube with a sharp edge, while the scraper is a flat sheet. In teaching, it is commonly used to prepare experimental samples. The scraper can be used to trim the edge of the stopper, or to scrape a small amount of solid reagents (such as sulfur powder, metal shavings), and can also clean residual substances in the mortar and evaporating dish. Helping students standardize the handling of experimental consumables, improve device assembly efficiency, and cultivate fine operational skills is a auxiliary tool in the experimental preparation stage.
