250mL Classic Grinding Bowl, Agate

250mL Classic Grinding Bowl, Agate

Introducing the 250mL Classic Grinding Bowl, meticulously crafted from premium Agate – an essential accessory for your Fritsch Classic Planetary Mill. These robust grinding bowls are specifically designed to safely contain both the grinding balls and the material you wish to process, ensuring optimal milling performance.

Our Classic Grinding Bowls are available in a diverse range of materials, each carefully selected to cater to the specific requirements of various grinding applications. Every bowl comes complete with a perfectly fitted lid and a high-quality seal ring, guaranteeing secure operation and preventing sample loss during the milling process.

Key considerations for optimal performance:

• Material Hardness: Always ensure that the grinding bowl material is significantly harder than the sample material being ground to prevent contamination and wear.
• Balanced Operation: For multi-station planetary mills, maintaining balanced loads is crucial. We recommend ensuring that the bowls, grinding balls, and sample volumes are consistent across all grinding stations. If a station is not in use or has a lighter load, a counterweight (such as fine sand material of equal total mass) should be placed in an empty jar to maintain mill stability and efficiency.
• Grinding Balls: Please note that Grinding Balls are sold separately, allowing you to select the ideal material and size for your specific application.
