8 × 6–10 mL Vacutainer Insert for Z366-250 Bucket (2/pk)

The Z366-250-A10 is an 8-position 6–10 mL Vacutainer-style tube insert for the Hermle Z366-250 swing-out bucket on the Z366 / Z366-K chassis 4-place rotor, sold as a 2-pack. Each insert holds 8 × 6–10 mL Vacutainer tubes; the 4-bucket rotor configuration takes 2 packs (4 inserts) for full symmetric loading, delivering 32 × 10 mL Vacutainer tubes per cycle in swing-out geometry on the cold-chain Z366-K chassis. The Z366-250 swing-out rotor reaches −2 °C at max speed on the refrigerated chassis, among the coldest cold-chain temperatures in the Hermle swing-out family, useful for cold-stable analyte and protein workflows.

Key Specifications

Compatibility & When to Order This SKU

Insert pairing: Z366-250 swing-out bucket only. Order this SKU when:

1. Adding 10 mL Vacutainer-style clinical-blood-tube workflow to an existing Z366 / Z366-K install. Order 2 units for full 4-bucket symmetric loading (32 tubes/cycle).
2. Cold-chain clinical-blood-component prep. When the workflow uses the Z366-K refrigerated chassis at near-freezing temperature (−2 °C at max speed) for cold-stable analyte preservation.
3. Institutional clinical-research blood-pool processing. 32 × 10 mL Vacutainer per cycle is sized for institutional clinical-research and biobank intake workflows.
4. Replacement inserts if a current set is damaged or worn.

Application Profile

4-bucket symmetric loading. All 4 buckets must use matching A10 inserts for symmetric balance at 4,500 rpm.

Per-insert symmetric loading. Within each insert, the 8 tubes should be balanced symmetrically. Pair tubes by mass.

Mixed 6 / 8 / 10 mL Vacutainer-style format flexibility. The insert envelope (16 mm OD, 75–100 mm length range) accommodates 6 mL, 8 mL, and 10 mL Vacutainer-style tube formats; the same insert serves multiple tube sizes within the supported range.

Cold-chain temperature capability. The Z366-K chassis maintains −2 °C at max operating speed, among the coldest cold-chain temperatures in the Hermle swing-out family. Useful for protocols requiring near-freezing cold-chain integrity.

Design Architecture

Cold-chain clinical-blood-component prep at near-freezing temperature. When the workflow needs the Z366-K's −2 °C cold-chain integrity for cold-stable analytes (some protein assays, some metabolomics studies, some pre-analytical preservation protocols).

Institutional clinical-research recruitment. Clinical-research workflows that batch many 10 mL Vacutainer samples per cycle for serum/plasma separation with cold-chain integrity.

Biobank intake at institutional throughput. Biobank workflows handling 10 mL primary collection tubes that need refrigerated centrifugation before aliquot prep for cryostorage.

Hospital reference labs. Clinical chemistry and hematology prep workflows at institutional throughput on the Z366-K platform with deep cold-chain capability.

Veterinary clinical at scale. Veterinary blood-component separation in 10 mL Vacutainer-style tubes for institutional veterinary practice or veterinary-research lab throughput.

Cross-format Z366-K core facilities: shared cores running 10 mL Vacutainer alongside other tube and bottle formats benefit from stocking the full Z366-250 insert family.

Ordering & Configuration

4-bucket symmetric loading. All 4 buckets must use matching A10 inserts. Mixed-bucket configurations produce mass asymmetry.

Tube cap confirmation. All Vacutainer rubber stoppers must be fully seated before spinning at 4,500 rpm.

Z366-250-A10 ships as 2 inserts. 6–10 mL Vacutainer-style tubes are operator-supplied (commodity clinical phlebotomy supplies). The Z366-250 bucket is sold separately.

Confirm at quote: bucket pairing (Z366-250 in inventory), chassis pairing (Z366 or Z366-K), tube format (6–10 mL Vacutainer-style), pack count (2 packs for full 4-bucket configuration), workflow drivers (cold-chain temperature requirement), and lead time.

Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the inserts.

Z366-250 bucket clinical-blood-tube insert family (Z366 / Z366-K chassis):

- Z366-250-A10 (this product): 8 × 6–10 mL Vacutainer (32/cycle)

- Z366-250-A57: 14 × 1.8–7 mL pediatric / small-volume blood tubes (56/cycle, highest small-volume throughput)

- Z366-250-A15: 7 × 15 mL conical (28/cycle)

- Z366-250-B10: 12 × 10 mL direct-fit bucket (48/cycle, higher throughput)

Match the insert to the workflow's clinical blood-tube format and target throughput. The Z366-K chassis's −2 °C cold-chain capability distinguishes the Z366-250 system from other Hermle swing-out rotors.
