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.
