The coal sample processing tools, stainless steel cleaning samples, and sampling shovel baffles in the laboratory are essential equipment. The laboratory grain depot coal sample scraper is a tool used to scrape coal samples. It is usually made of stainless steel and has characteristics such as corrosion resistance and easy cleaning. The stainless steel sample plate is a tool used to divide coal samples into different parts, with a smooth surface that is not prone to residual coal samples, ensuring the accuracy of analysis. The sampling shovel baffle is a device used to block the flow of coal samples. It is usually made of wear-resistant materials and can withstand frequent use and friction. The shrinkage board is used to divide coal samples into smaller samples for subsequent analysis and testing. These tools play an important role in the laboratory, ensuring the accuracy and reliability of experimental data, and providing important support for laboratory research and experiments. The coal sample processing tools in the laboratory not only ensure the smooth progress of scientific research experiments, but also provide important guarantees for our energy security.
