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.

Why the GL45 Thread — Lab-Industry Standard
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:
- Workflow involves standard media / buffer / reagent storage at the 1 L volume scale
- Multi-bottle procurement — 10-bottle pack supports facility-scale storage workflows
- Color-coded bottle organization — blue caps for one storage class (e.g., media); pair with other-color caps in the family if needed for differentiation
- GL45-accessory-compatible workflow — facility uses dispensing / sampling / stirring accessories at the GL45 cap interface
Pack-Size Family — B3000 hybex Bottles (Blue Cap)
| 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.
Application Profile
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.
Ordering & Configuration
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
- B3000-1000-B (this product) — 1000 mL × 10/pk ($217, $21.70/bottle) — standard media-storage workhorse
Pick the 1000 mL pack for standard media / buffer / reagent storage at the 1 L scale; sister 100 mL pack covers smaller-format storage workflows.
