The B3000-1000-B is the 1000 mL hybex Media storage bottle with standard GL45 blue cap, sold as 10-bottle pack at $217 ($21.70 per bottle). The GL45 thread is the lab industry-standard cap thread (DIN 168-1 GL45 dimension), compatible with standard lab bottle cap accessories (vented caps, dispensing caps, magnetic stir caps, sampling caps) across the lab consumables ecosystem. The blue cap color is the standard color-coding default in many facilities. Color-coded caps support at-a-glance bottle identification in shared-facility storage.
Author confidence note (MEDIUM): No specific B3000 brochure in available corpus. Specs sourced from universe label. Confirm exact bottle material (likely Type I borosilicate glass), cap material (likely PP; polypropylene), autoclave compatibility, and exact pack quantity with Benchmark Scientific technical support at first procurement.

GL45 is the dominant lab-bottle cap-thread standard for media storage bottles in the 0.1 – 5 L volume range. It is compatible with standard solid screw caps and vented autoclave-safe caps, dispensing accessories (dispenser bottles, automatic dispenser tops), sampling accessories (septum and sampling-port caps), filter-vent caps for sterile filtration workflows, stir-bar-compatible caps for in-bottle stirring, and sterile transfer connectors for downstream tubing connections.
Pick the hybex GL45 1000 mL bottle (B3000-1000-B) when:
| SKU | Volume | Per-bottle cost | List price (10/pk) |
| B3000-100-B | 100 mL | $12.94 | $129 |
| B3000-1000-B (this product) | 1000 mL | $21.70 | $217 |
Per-bottle cost is non-linear with volume. The 10× volume increase from 100 mL to 1000 mL costs only ~68 % more per bottle, reflecting fixed per-bottle manufacturing costs (cap, thread machining, packaging) that scale less than proportionally with volume.
Cell-culture media storage. 1 L bottles are the standard format for media storage in cell-culture rooms.
Buffer / reagent storage. Bulk buffer prep, bulk-reagent storage at the 1 L scale.
Autoclavable storage. Bottles are typically autoclave-safe with vented caps; sterile media storage workflows.
Color-coded storage organization. Blue caps for media; if facility needs cap-color differentiation across storage classes, confirm other-color hybex variants at order.
Multi-investigator shared-facility procurement. 10-bottle pack supports facility-scale bottle-rotation workflows.
Educational laboratory teaching. Undergraduate / graduate molecular biology coursework where each student-cohort exercise uses 1 L bottle aliquots.
Method-development workflows. Protocol-development requiring standardized 1 L bottle storage across protocol versions.
Confirm bottle and cap material. GL45 caps are typically PP; bottles are typically Type I borosilicate glass. Confirm exact materials at order if workflow has specific chemistry / autoclave / temperature requirements.
Confirm autoclave compatibility. Most hybex bottles are autoclave-safe with vented caps (solid screw caps create pressure during autoclaving; risk of cap deformation or cracking). Confirm intended autoclave protocol at order.
Confirm cap color availability across the family. If facility needs multi-color cap-coding for storage organization, confirm other cap-color SKUs in the B3000 family at order.
Plan for bottle-rotation cycle. Glass bottles are durable but eventually accumulate scratches / chips that compromise sterility. Plan periodic replacement at facility scale.
Confirm at quote: bottle / cap material, autoclave compatibility, cap-color organization plan, intended workflow scale (single-investigator vs facility), and lead time.
Warranty: Per Benchmark Scientific standard consumable terms. Confirm at quote.
hybex Media Storage Bottle family (Blue cap):
- B3000-100-B (100 mL × 10/pk ($129, $12.94/bottle)) small-format storage
