Agate Grinding Jar
High purity natural Brazilian agate (99.91% SiO2) bowl, highly wear-resistant and resistant to acids (except HF) and solvent, these bowls are used whenever small quantity of samples need to be ground without contamination. The agate bowls are extensively applied in the fields of Ceramics, Electronics, Light Industry, Paint, Ink, Medicine, Food, Geology, Chemical Engineering and so on. Agate bowl is a highly wear resistant grinding tank. The agate bowl developed by our factory is made of high-quality imported materials and has a bright and clean appearance, high hardness, good toughness, resistance to various solvents (such as acetone and alcohol), high abrasion resistance, no pollution, and long service life.
