80mL Classic Grinding Bowl, Sintered Corundum

80mL Classic Grinding Bowl, Sintered Corundum: Precision for Demanding Samples

The 80mL Classic Grinding Bowl, meticulously crafted from high-purity Sintered Corundum, is an essential component for achieving superior grinding results with the Fritsch Classic Planetary Mill. Designed for demanding applications, this bowl effectively contains grinding balls and the material to be processed, ensuring maximum efficiency and minimal contamination.

Key Features & Benefits of Sintered Corundum:

• Exceptional Hardness: Sintered Corundum (Al₂O₃) is renowned for its extreme hardness, making it ideal for grinding very hard and abrasive materials without significant wear to the bowl itself. This prevents unwanted contamination of your sample.
• High Abrasion Resistance: Its robust nature ensures a long service life, even under intensive use, providing consistent performance over time.
• Chemical Inertness: Corundum is chemically resistant to most acids and alkalis, making it suitable for a wide range of sensitive samples where chemical interaction must be avoided.
• Contamination-Free Grinding: Perfect for applications requiring high purity, such as in ceramics, geology, metallurgy, and material science, where trace element contamination can compromise analysis.

Included Components: Each grinding bowl comes complete with a perfectly matched lid and a durable seal ring. These components are crucial for:

• Preventing Material Loss: Ensuring no sample material escapes during high-speed grinding.
• Maintaining Controlled Atmospheres: Allowing for grinding under vacuum or inert gas conditions, which is vital for oxygen-sensitive materials or preventing oxidation.

Optimizing Your Grinding Process: For best results and to prolong the life of your equipment, adhere to the following guidelines:

• Material Hardness: Always select a grinding bowl material that is significantly harder than your sample material to ensure efficient reduction and prevent bowl wear.
• Balanced Loads: When using multi-station mills, it's imperative to operate with balanced loads. Inconsistent weights can lead to excessive vibration, uneven wear, and suboptimal grinding outcomes. We recommend using a fine, inert sand (e.g., play sand) of equal total mass as a counterweight in empty stations.
• Consistency: Maintain consistent bowls, grinding balls, and sample volumes across all active grinding stations for uniform results.
• Grinding Balls: Grinding balls are purchased separately. For Sintered Corundum bowls, suitable ball materials include corundum, zirconia, or silicon nitride, depending on your sample's specific properties and purity requirements.

Capacity: The 80mL bowl offers an optimal effective grinding volume of 10–30 mL, allowing for precise control over your sample quantity.

Choose the 80mL Sintered Corundum Grinding Bowl for reliable, high-purity, and efficient processing of your most challenging samples.
