LAARMANN Agate Polished Grinding Balls are premium milling media designed for use in all planetary ball mills. They are ideal for high-purity grinding applications where contamination must be kept to an absolute minimum.
Made from natural agate (SiO₂), these balls offer excellent hardness, smooth surface finish, and exceptional chemical inertness. Their polished surface reduces friction and prevents sample adhesion, ensuring consistent and reproducible grinding results.
Universal compatibility: Suitable for all planetary ball mills
Material: Natural agate (SiO₂)
High purity: Extremely low contamination for sensitive samples
Polished surface: Minimizes friction and sample loss
Chemical resistance: Highly inert and resistant to most acids
