Why Stainless Steel Grinding Jars Prevent Contamination in Laboratory Grinding

The grinding jars are made of SUS304 stainless steel, featuring a smooth surface and precise craftsmanship. The inner surface of the jars is coated with a chromium-rich oxide layer (passivation film), providing rust resistance and acid resistance. This ensures excellent corrosion resistance against organic and inorganic acids of varying concentrations and temperatures, particularly in oxidizing environments. Additionally, the smooth inner walls of the stainless steel grinding jars effectively prevent sample adhesion or clumping,
