The Z496-750-BLD is the blood-bag bucket for 750 mL bag format on the Hermle Z496-K family — sold as a 2-pack (a complete 4-bucket set for the Z496-1000-AC rotor body requires 2 units = 4 buckets). Engineered specifically for 750 mL plasma and blood-component bags, this bucket holds the bag at the correct orientation for swing-out separation at 4,600 rpm / 5,274 × g. For blood-banking, plasmapheresis, and component-therapy workflows that handle 750 mL bag-format products, this is the chassis-spec bucket on the Z496-K family.

Compatibility & When to Order This SKU
This SKU is the blood-bag bucket only. Order Z496-750-BLD when the workflow includes 750 mL plasma or blood-component bag separation on the Z496-K chassis. Compatible specifically with the Z496-1000-AC rotor body — pair with 2 units for a complete 4-bucket configuration, or order single units to add blood-bag capability to an existing tube/bottle bucket inventory.
Blood-bag vs round vs rectangular bucket selection on Z496-K:
| Bucket | Format | Use case |
| Z496-1000-1L | 1,000 mL round | Tube/bottle workflows, deep adapter library |
| Z496-1000-RBUK | 1,000 mL rectangular | Microplate-direct loading + tube inserts |
| Z496-750-BLD (this product) | 750 mL blood bag | Blood-banking + component-therapy workflows |
| Z496-500-BLD | 500 mL blood bag | Smaller blood-bag format |
Mixing bucket profiles is not supported — all 4 positions on the rotor must use the same bucket type for symmetric balance. For mixed workflows (some blood-bag, some bottle), order both bucket types and swap full sets between protocols.
Application Profile
Blood-banking 750 mL bag separation — the primary use case. Whole-blood bag fractionation into red cell concentrate, plasma, and platelet-rich plasma; the 5,274 × g RCF and refrigerated chassis option support standard blood-component separation protocols.
Plasmapheresis prep. Donor plasma collection in 750 mL bags, with the centrifugal separation step processing 4 bags per cycle on the Z496-K.
Component-therapy preparation — cryoprecipitate, platelet pheresis, and similar blood-product workflows in 750 mL bag format.
Cold-chain blood-component work when paired with Z496-K refrigerated chassis. The 9 °C temperature-at-max-speed spec supports the cold-chain integrity required by AABB and similar blood-banking standards.
Research-grade blood-bag separation in academic blood-banking research, transfusion medicine research, and clinical-trials sample prep workflows.
Ordering & Configuration
4-bucket symmetric loading. Pair opposite blood-bag buckets by total mass (bag + sample volume). Blood-bag mass varies meaningfully with fill volume; per-spin pre-balance is operator responsibility.
Bag orientation. Bags load into the bucket per the Z496-750-BLD bucket geometry — confirm bag-fold and connector-tubing orientation per Hermle service instructions.
Z496-750-BLD ships as 2 blood-bag buckets. The Z496-1000-AC rotor body is sold separately; for full 4-bucket operation, order 2 units of this SKU. The Z496-750-ADP bucket adapter (for tube-format inserts inside the bag bucket) is also sold separately.
Confirm at quote: Z496-1000-AC rotor body inventory, bucket count needed (2 or 4), chassis pairing (Z496-K or Z496-K-UC), Z496-750-ADP adapter inclusion if tube-format work shares the bucket, training, and lead time.
Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the buckets. Includes manufacturing-defect coverage; bucket service-life inspection is part of the standard Hermle service interval recommendation. Blood-banking facilities should follow AABB and applicable regional regulatory inspection guidelines on top of the manufacturer recommendation.
Z496-750-BLD vs Z496-500-BLD selection: the Z496-750-BLD (this product, 750 mL bag) is the larger bag-volume pick. The Z496-500-BLD ($3,437 for 2-pack) handles 500 mL bag format. Pick based on the dominant blood-bag size in the lab's workflow; many blood-banks order both bucket sizes to handle the full bag-volume range.
