The D1031-10 is the 1.0 mm silica bead variant — 50 tubes per pack at $136. Largest-bead silica format for tougher tissue samples (plant tissue, fibrous samples) where 0.1 mm and 0.5 mm beads provide insufficient kinetic energy.
For full chemistry rationale, see the D1031-01 (anchor) page.

When to Pick the 1.0 mm Bead
Pick the D1031-10 when:
- Workflow involves tougher tissue — plant tissue, fibrous samples, dense matrices
- Higher kinetic energy per impact required (larger bead = more mass per impact)
For even tougher samples, step to the D1032 Zirconium bead family ($189 / 50pk) — zirconium has higher density than silica, providing more kinetic energy per impact.
Ordering & Configuration
