Replacement Cap, Standard Blue , 10/pk

The B3000-CAP2 is the GL32 thread replacement cap for the hybex 50 mL bottle (B3000-50) — 10 caps per pack at $41 ($4.10 per cap). The smaller GL32 thread is the standard for 50 mL bottles (not interchangeable with the GL45 used across the rest of the hybex family).

For full rationale (cap-replacement workflow, autoclave compatibility, color-coding strategy, replacement timing), see the B3000-CAP (GL45) parent page.

Key Specifications

Critical Thread-Compatibility Note

B3000-CAP2 (GL32) and B3000-CAP (GL45) are NOT cross-compatible. The GL32 cap fits the 50 mL bottle (B3000-50) only — the larger 100–10,000 mL hybex bottles use GL45 thread and require the B3000-CAP GL45 cap.

Ordering & Configuration

Confirm thread compatibility before ordering. B3000-CAP2 = GL32 only (B3000-50 bottle). For all larger bottles (GL45), order B3000-CAP instead.

Plan for ongoing replacement cycle — same protocol as B3000-CAP, applied to the 50 mL bottle inventory.

Confirm at quote: cap thread (GL32), bottle inventory match (B3000-50 only), autoclave compatibility, and lead time.

Warranty: Per Benchmark Scientific standard consumable terms.
