Cell Lab High-Purity Natural Agate Milling Jar [99.91% SiO₂ | 50 ml – 1 L]

Precision grinding jar for contamination-free planetary milling

The Cell Lab™ High-Purity Natural Agate Milling Jar is meticulously hand-crafted from Brazilian natural agate containing ≥ 99.91 % SiO₂, offering exceptional hardness, chemical resistance, and purity. Designed for planetary ball mills and other high-energy milling systems, these jars ensure minimal sample contamination and uniform particle size reduction for demanding laboratory and industrial research applications.

Each jar includes a precision-fit lid and rubber sealing gasket for airtight grinding, ensuring clean and reproducible milling results under both wet and dry conditions.

Key Features

• Ultra-High-Purity Natural Agate (≥ 99.91 % SiO₂)
Manufactured from premium Brazilian agate with near-zero metallic impurities, ensuring analytical-grade sample integrity.

• Superior Mechanical Strength and Density
High hardness (Mohs 6.5 – 7) and specific gravity 2.65 g/cm³ enable consistent grinding efficiency and long service life.

• Excellent Chemical Inertness
Highly resistant to most acids and solvents (except HF), making it ideal for use in chemical, geological, and materials research.

• Mirror-Polished Non-Porous Surface
Smooth internal finish prevents sample adhesion, simplifies cleaning, and reduces cross-contamination risk.

• Crack-Resistant Cylindrical Design
Withstands high-speed impacts and centrifugal forces in planetary ball mills.

• Wide Compatibility
Fits most planetary and laboratory-scale ball mill systems, ensuring easy replacement and flexible experimental setup.

    Jar & Media Compatibility Tips

    To achieve the best grinding performance, always match the jar and milling media materials.
    For example, a 250 ml agate jar pairs best with approximately 250 g of mixed-size agate balls.
    Optimisation may vary with sample hardness, brittleness, and grinding duration.

    FAQ

    Q1: Why choose agate jars over zirconia or stainless-steel?
    A1: Agate provides superior chemical purity and ultra-low contamination, critical for trace-element and high-precision research.

    Q2: Can agate jars handle both wet and dry milling?
    A2: Yes — they are suitable for both conditions, maintaining stable performance and easy cleaning.

    Q3: How should I clean the jar after use?
    A3: Rinse with ethanol or deionised water using a soft brush or lint-free cloth; avoid metal tools.

    Q4: Are the jars compatible with high-energy planetary mills?
    A4: Yes — each jar is precision balanced and impact-resistant, making it safe for high-speed planetary operation.

    Q5: What material should I choose for matching grinding balls?
    A5: Use agate milling balls of the same purity for optimal results and lowest abrasion.
