METICULAB™ Precision Sapphire Ruby Balls | G3 G5 G10 Grade | 0.30-12.00mm | Check Valve & Metrology
METICULAB™ Precision Sapphire Ruby Balls | G3 G5 G10 Grade | 0.30-12.00mm | Check Valve & Metrology
The Sphere That Never Wears: Ruby and Sapphire Precision Balls for Mission-Critical Fluid and Measurement Systems
When an HPLC check valve cycles at 100 strokes per minute or a CMM probe touches a thousand surfaces a day, the ball at the contact point must remain perfectly spherical — or the system fails. METICULAB™ Precision Spheres are ground and lapped to G3 grade roundness of 0.08um from single crystal synthetic ruby and sapphire, providing the ultimate wear surface for your most demanding fluid control and metrology applications.

Why METICULAB™ Precision Spheres?
- G3 Grade at 0.08um Roundness: Our highest precision grade achieves sub 0.1um sphericity, essential for HPLC check valves and metrology probe tips where contact geometry defines measurement accuracy.
- Blind Hole from 0.20mm: Precision drilled and lapped blind holes for CMM styli, available across all diameter ranges from 0.30mm micro balls to 12.00mm industrial spheres.
- Matched Ball and Seat Service: Individual lapping and pairing for perfect sealing in check valve applications. Eliminates leakage and extends pump service intervals.
- Ruby or Sapphire for Your Application: Ruby for high visibility during precision assembly. Sapphire for transparent optical alignment. Same Mohs 9 hardness, same wear resistance.
