Key Features of Corundum Mill Jars
Designed for Nano-Grade Milling
The sealed jar system is the professional solution for achieving ultra-fine particle size in a planetary ball mill.
Zero Product Contamination
Made from high-purity, oxidation-resistant corundum. Its smooth, wear-resistant surface prevents material shedding into your sample.
Long Service Life & High Hardness
Imported raw materials provide superior durability and high wear resistance for a long service life.
For High-Value Materials
The non-contaminating, corrosion-resistant properties make it the ideal choice for grinding precious metals and advanced electronic ceramics.
