Why Bulk Beads vs Prefilled Tubes
| Procurement option | Cost per equivalent 50 tubes | Best for |
| Prefilled tubes (D1031-01, $136 / 50pk) | $136 ($2.72/tube) | Standard workflows, no facility loading required |
| Bulk beads (D1131-01, this product) + empty tubes (D1031-T20, $0.20/tube) | ~$10 (bulk beads) + $10 (50 tubes) = $20 | Custom bead loading, facility-scale economics |
Substantial cost savings at scale — 50 tubes loaded with bulk silica costs ~$20 vs $136 for prefilled — but requires facility-loaded workflow. Bulk procurement breaks even around 7 prefilled-tube-pack equivalents depending on per-tube bead-mass loading.
Pick the D1131-01 when:
- Facility runs high-throughput BeadBug workflows at scale where bulk bead economics matter
- Custom bead-mass loading — facility wants different bead-mass-per-tube than prefilled SKUs provide
- Method-development workflows comparing bead-mass effects on disruption efficiency
