The D1031-RFS is the reinforced 2 mL screw-cap skirted tube — 600 tubes per pack at $372 ($0.62 per tube). Reinforced wall + screw cap + skirted base design for high-RCF microcentrifuge workflows where standard snap-cap tubes pop open under centrifugal force.
CRITICAL COMPATIBILITY WARNING: Universe label flags "not for BeadBug 3". Despite the D1031-* SKU prefix (D1031 family is otherwise BeadBug 3 prefilled tubes), this SKU is NOT compatible with the BeadBug 3 (D1030) chassis — likely intended for high-RCF microcentrifuge workflows (C1612 MC-12, C2417 MC-24 family) where the reinforced design prevents tube failure under centrifugal force.

High-RCF centrifugation (>15,000 g) stresses standard 2 mL Eppendorf tubes:
The D1031-RFS combines all three reinforcements — reinforced wall + screw-cap (vs snap-cap) + skirted base — for reliable high-RCF performance without tube failure.
Confirm chassis compatibility BEFORE PROCUREMENT. Universe explicitly flags non-compatibility with BeadBug 3 — confirm intended high-RCF chassis (C1612 / C2417 family, etc.) with Benchmark Scientific tech support.
Confirm at quote: chassis compatibility (NOT BeadBug 3), high-RCF workflow context, and lead time.
Warranty: Per Benchmark Scientific standard consumable terms.
D1031-RFS critical compatibility note:
- NOT compatible with BeadBug 3 (D1030)
- Likely compatible with high-RCF microcentrifuges (confirm at order)
Confirm chassis compatibility before procurement to avoid order error.
