500 mL Blood-Bag Bucket for Z496-1000-AC (2/pk)

The Z496-500-BLD is the blood-bag bucket for 500 mL bag format on the Hermle Z496-K family — sold as a 2-pack (full 4-bucket set requires 2 units = 4 buckets). The 500 mL bag size covers smaller plasma collection workflows, partial-fill blood-component bags, and pediatric blood-banking workflows where the standard 750 mL bag is over-sized. At 4,600 rpm / 5,298 × g (slightly higher RCF than the 750 mL bucket due to longer max radius at the smaller bag envelope), this bucket delivers the spec required for clinical blood-component separation in the smaller bag format.

Key Specifications

Compatibility & When to Order This SKU

This SKU is the 500 mL blood-bag bucket only. Order Z496-500-BLD when the workflow includes 500 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.

500 mL bag format use cases:

• Pediatric blood-component therapy — smaller-volume collections that don't fill a standard 750 mL bag
• Partial-fill plasma collection — donor-specific or research-protocol collection volumes below 750 mL
• Blood-banking research at non-production scale where 500 mL is the sample volume
• Plasmapheresis preparation for smaller-volume protocols

500 vs 750 mL blood-bag bucket selection on Z496-K:

The 500 mL bucket reaches slightly higher RCF (5,298 vs 5,274 × g) due to marginally longer max radius (22.4 vs 22.3 cm) — at this RCF class the difference is operationally indistinguishable, but documented for completeness.

Mixing bucket sizes on the same rotor is not supported — all 4 positions must use the same bucket type. Many blood-banks own both 500 and 750 mL bucket sets and swap between them based on protocol.

Application Profile

Pediatric blood-component therapy preparation — pediatric transfusion volumes typically don't fill a standard 750 mL bag; the 500 mL bucket holds the partial-fill bag at the correct centrifugation orientation.

Smaller-volume plasmapheresis prep — donor plasma collection in 500 mL bags for protocol-specific volumes.

Blood-banking research and clinical trials that specify 500 mL collection volume.

Component-therapy intermediate steps where a 750 mL bag is split into 500 mL aliquots for downstream processing.

Cold-chain blood-component work when paired with Z496-K refrigerated chassis. The 7 °C temperature-at-max-speed spec supports cold-chain integrity for blood-component separation.

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, especially important for partial-fill bags where mass variation across positions is more pronounced.

Bag orientation. Bags load into the bucket per the Z496-500-BLD bucket geometry — confirm bag-fold and connector-tubing orientation per Hermle service instructions.

Z496-500-BLD ships as 2 blood-bag buckets. Z496-1000-AC rotor body is sold separately; the Z496-500-ADP bucket adapter (for tube-format inserts) 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), Z496-500-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. Manufacturing-defect coverage; service-life inspection per Hermle service interval recommendation, plus AABB and applicable regional regulatory inspection guidelines for blood-banking facilities.

Blood-bag bucket selection: match the bucket to the dominant bag size in the workflow. For mixed 500 / 750 mL workflows, many blood-banks own both bucket sets — the Z496-K rotor body supports either configuration with the appropriate bucket installation.
