The B3220-2000 is the largest capped Erlenmeyer in the hybex B3220 family — 2000 mL single flask at $89 ($88.67 per flask). Same integrated GL45 cap design as the 1000 mL sister, scaled to the larger 2 L volume for production-scale capped shake-flask workflows.
For full chemistry rationale (capped vs open-mouth Erlenmeyer decision, sealed-storage workflows, cap-accessory ecosystem), see the B3220-1000 (1000 mL) anchor page.

When to Pick the 2 L Capped Erlenmeyer
Pick the B3220-2000 when:
- Workflow uses 2 L shake-flask cultures requiring sealed-container storage between uses
- Production-scale cell culture / protein expression at the 2 L flask format with sterile storage
- Bioreactor seed cultures where sealed-cap storage of the seed flask supports sterility
- Cell-culture facility production-scale procurement at the largest B3220 flask format
Stay with B3220-1000 (1000 mL × 6/pk) when smaller-volume capped flasks + multi-flask pack procurement fits the workflow.
Stay with B3110-2000 (uncapped, $34) when open-mouth 2 L Erlenmeyer workflow is the routine — $89.00 saving when the integrated cap isn't required.
Capped Erlenmeyer Family — Pack-Size
| SKU | Volume | Pack | Per-flask cost |
| B3220-1000 | 1000 mL | 6/pk | $40.50 |
| B3220-2000 (this product) | 2000 mL | 1/each | $88.67 |
Ordering & Configuration
Pair with cap accessories per workflow — see B3220-1000 parent for full pairing matrix.
Confirm autoclave protocol. Vented-cap pairing mandatory at the 2 L scale (pressure-buildup risk during autoclave is significant at large volumes).
Confirm two-person handling protocol. Filled 2 L flasks are heavy and bulky — confirm handling protocols at facility scale.
Confirm at quote: flask material, cap material (PP vs PBT), autoclave protocol (vented-cap pairing mandatory), workflow context, handling protocol, and lead time.
Warranty: Per Benchmark Scientific standard consumable terms.
