Cell Lab Yttria-Stabilised Zirconia YSZ Micro Milling Media

The Cell Lab Yttria-Stabilised Zirconia (YSZ) Micro Milling Media range is designed for laboratories and pilot-scale production requiring precise, contamination-free grinding. Available in multiple bead sizes from 0.1 mm to 2.5 mm, these high-purity zirconia microbeads combine exceptional density, fracture toughness, and low wear loss. Their narrow size distribution and consistent sphericity enable reproducible ultrafine grinding, dispersion, and homogenisation across coatings, inks, pharmaceuticals, electronic slurries, battery powders, and biotech sample preparation.

Key Features

• High purity & chemical stability – Produced from nano-scale YSZ precursors with advanced co-precipitation technology, ensuring minimal contamination.

• Outstanding wear resistance – Demonstrated ~15% lower wear rate than ceria-stabilised zirconia beads, extending operational lifespan.

• High density & fracture toughness – Ensures efficient energy transfer, superior grinding efficiency, and maximum throughput.

• Narrow size distribution – Uniform bead sizes provide consistent milling results and reproducibility across batches.

• Versatile range of bead sizes – From 0.1 mm microbeads for DNA/RNA extraction to 2.5 mm beads for robust dispersion and particle reduction.

FAQ

Q1: How do I select the right bead size?
A: Use smaller beads (0.1–0.5 mm) for ultrafine grinding and biotech sample preparation; mid-size beads (0.6–1.4 mm) for coatings, inks, and slurries; larger beads (1.8–2.5 mm) for high-viscosity dispersions and mineral grinding.

Q2: Why are YSZ beads superior to ceria-stabilised zirconia?
A: YSZ offers ~15% lower wear rate, higher fracture toughness, and longer service life, reducing contamination and cost over time.

Q3: Can these beads be used in high-energy mills?
A: Yes. Their high density and strength make them ideal for planetary mills, stirred media mills, and bead mills operating at high RPM.

Q4: Are they safe for pharmaceutical and biotech use?
A: Absolutely. Their high chemical purity and inertness make them ideal for DNA/RNA extraction and protein isolation.

Q5: What is the typical lifespan of these beads?
A: With proper use, YSZ beads last significantly longer than glass, alumina, or ceria-stabilised alternatives, offering excellent cost-effectiveness.
