4 × 5 mL Conical Insert for Z327-200-BUK (2/pk)

The Z327-200-A5F is a 4-position 5 mL conical tube insert for the Hermle Z327-200-BUK swing-out bucket on the Z327 / Z327-K chassis 4-place rotor — sold as a 2-pack. Each insert holds 4 × 5 mL conical tubes; the 4-bucket rotor configuration takes 2 packs (4 inserts) for full symmetric loading, delivering 16 × 5 mL conical tubes per cycle in swing-out geometry. Distinct from the sister A57 insert (which serves 1.8–7 mL Vacutainer-style round-bottom tubes), the A5F is sized for the 5 mL conical format specifically — a distinct tube envelope used in some clinical-research and bioprocess workflows.

Key Specifications

Compatibility & When to Order This SKU

Insert pairing — Z327-200-BUK swing-out bucket only. Order this SKU when:

1. Adding 5 mL conical workflow to an existing Z327 / Z327-K + Z327-200 install — order 2 units for full 4-bucket symmetric loading (16 tubes/cycle).
2. 5 mL conical clinical-research workflows — clinical-research and bioprocess protocols that use 5 mL conical tubes (vs 5 mL Vacutainer-style round-bottom).
3. Cold-chain 5 mL conical aliquot prep on the Z327-K refrigerated chassis.
4. BSL-2 + 5 mL conical workflows with the Z327-200-LID engaged for hermetic containment.
5. Replacement inserts if a current set is damaged or worn.

A5F vs A57 — Conical vs Vacutainer Distinction

The Z327-200 small-volume insert pair differs by tube envelope geometry:

The A5F is shorter (60–70 mm length) and slightly wider (17 mm OD) than the A57 envelope — engineered for the conical 5 mL tube geometry. Pick A5F when the workflow specifies 5 mL conical tubes; pick A57 when the workflow uses 5 mL or 7 mL Vacutainer-style round-bottom tubes.

Application Profile

4-bucket symmetric loading. All 4 buckets must use matching A5F inserts for symmetric balance.

Per-insert symmetric loading. Within each insert, the 4 conical tubes should be balanced — pair tubes by mass.

Optional hermetic seal via LID. When combined with the Z327-200-LID, the bucket creates a hermetic envelope for BSL-2 + 5 mL conical workflows.

Design Architecture

5 mL conical clinical-research aliquot prep — clinical-research workflows that aliquot patient samples into 5 mL conical for downstream analytical batch shipping.

Cold-chain 5 mL conical bioprocess intermediate prep — vaccine-development, recombinant-protein, and bioprocess workflows that batch 5 mL conical aliquots for intermediate concentration steps with cold-chain integrity.

BSL-2 + small-volume clinical workflows — when 5 mL conical clinical-research samples handle potentially infectious patient material requiring aerosol containment via the Z327-200-LID.

Mid-throughput cold-chain 5 mL conical workflow — when 16 × 5 mL conical parallel throughput matches the workflow's batch size on the cold-chain swing-out chassis.

Veterinary clinical workflows in 5 mL conical — small-animal blood-component separation in 5 mL conical format.

Cross-format Z327-K core facilities — labs that handle both 5 mL conical and other small-volume tube formats benefit from stocking both A5F and A57 inserts.

Ordering & Configuration

4-bucket symmetric loading. All 4 buckets must use matching A5F inserts. Mixed-bucket configurations produce mass asymmetry.

Per-insert symmetric loading. Within each insert, pair the 4 tubes symmetrically by mass.

Optional hermetic-seal engagement. When using the Z327-200-LID for biosafety workflows, confirm the lid is fully engaged on each bucket before each spin.

Tube cap confirmation. All conical tubes must be securely capped before spinning at 5,000 rpm.

Z327-200-A5F ships as 2 inserts. 5 mL conical tubes are operator-supplied (commodity 5 mL conical formats from major commercial suppliers). The Z327-200-BUK bucket and (optional) Z327-200-LID are sold separately.

Confirm at quote: bucket pairing (Z327-200-BUK in inventory; Z327-200-LID if biosafety required), chassis pairing (Z327 or Z327-K), tube format (5 mL conical, 17 mm OD; for Vacutainer-style round-bottom 5/7 mL use A57 instead), pack count (2 packs for full 4-bucket configuration), and lead time.

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

Z327-200 small-volume insert family (Z327 / Z327-K chassis):

- Z327-200-A5F (this product) — 4 × 5 mL conical (16/cycle)

- Z327-200-A57 — 8 × 1.8–7 mL Vacutainer round-bottom (32/cycle)

- Z327-200-A20 — 5 × 1.5/2.0 mL microtubes (20/cycle)

Match the insert to the workflow's tube envelope (conical vs Vacutainer round-bottom) and target throughput.
