200 mL Bottle Insert for Z327-200-BUK (2/pk)

The Z327-200-A200 is the 200 mL bottle 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 1 × 200 mL bottle; the 4-bucket rotor configuration takes 2 packs (4 inserts) for full symmetric loading, delivering 4 × 200 mL bottles per cycle (800 mL total per cycle) — the largest single-cycle volume in the Z327-200 insert family. The 0.0 cm radius correction preserves full rotor radius — the bottle sits at the bucket's full 14.8 cm radius for maximum RCF (4,136 × g).

Key Specifications

Compatibility & When to Order This SKU

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

1. Adding 200 mL bottle workflow to an existing Z327 / Z327-K + Z327-200 install — order 2 units for full 4-bucket symmetric loading (800 mL total per cycle).
2. Institutional bulk cell-prep workflows that batch 4 × 200 mL cultures or aliquots per cycle.
3. Bioprocess intermediate prep at 200 mL — vaccine-development, bioprocess workflows that use 200 mL bottles for intermediate concentration steps.
4. Optional cold-chain workflow on the Z327-K refrigerated chassis.
5. Optional BSL-2 + workflow with the Z327-200-LID engaged for hermetic containment.
6. Replacement inserts if a current set is damaged or worn.

Application Profile

4-bucket symmetric loading. All 4 buckets must use matching A200 inserts for symmetric balance. With full configuration, each cycle processes 800 mL of working volume — the largest single-cycle volume in the Z327-200 insert family.

Bottle format precision. The A200 envelope is dimensioned for the 56 mm OD × 112 mm length range. Bottles outside this dimensional range may not seat properly; verify dimensions if using non-standard bottle suppliers.

Full radius preserved. The 0.0 cm radius correction means the bottle sits at the bucket's full 14.8 cm radius — delivering the maximum RCF that the Z327-200 rotor configuration provides.

Optional hermetic seal via LID. Compatible with the Z327-200-LID for BSL-2 + bottle workflows.

Design Architecture

Institutional bulk cell harvest workflows — pelleting cells from 200 mL suspension culture batches; the 4 × 200 mL parallel throughput consolidates institutional prep in one cycle.

Vaccine-development and bioprocess intermediate prep at 200 mL — vaccine-development workflows that batch 200 mL bottles for intermediate concentration steps; the swing-out flat-sediment geometry supports clean phase separation.

Cold-chain bulk-volume bottle workflows on Z327-K — refrigerated 200 mL bottle workflows for cold-stable bioprocess intermediates.

Bulk-volume protein prep workflows — TCA, ammonium-sulfate, organic-precipitation in 200 mL working volume.

Environmental and analytical sample prep at scale — water, soil-extract, sediment-supernatant prep at 200 mL bottle scale for downstream analytical workflows.

BSL-2 + bulk-volume bottle workflows — recombinant-protein expression and bioprocess prep handling genetically modified organisms in 200 mL bottle format with hermetic containment.

Cross-format Z327-K core facilities — labs running 200 mL bulk-prep alongside smaller-volume bottle workflows (85 mL A85, 100 mL A100) on the same Z327-200 + Z327-200-BUK inventory.

Ordering & Configuration

4-bucket symmetric loading. All 4 buckets must use matching A200 inserts. Mixed-bucket configurations produce mass asymmetry.

Bottle cap confirmation. All bottles must be securely capped before spinning at 5,000 rpm — at 200 mL working volume, sample loss from a cap failure represents substantial sample volume.

Bottle volume balance. When the 4 bottles carry different sample volumes, pre-balance pairs by total mass before spinning. At 200 mL bottle scale, 1–2 mL volume differences don't materially affect balance, but >5 mL differences do.

Z327-200-A200 ships as 2 inserts. Bottles (200 mL, 56 mm OD) and the Z327-200-BUK bucket are sold separately. Z327-200-LID (optional) sold separately.

Confirm at quote: bucket pairing (Z327-200-BUK in inventory; Z327-200-LID if biosafety required), chassis pairing (Z327 or Z327-K), bottle format (200 mL, 56 mm OD), 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 bucket bottle-insert family (Z327 / Z327-K chassis):

- Z327-200-A200 (this product) — 200 mL bottle (largest single-cycle volume in the family — 800 mL total)

- Z327-200-A100 — 100 mL round-bottom glass

- Z327-200-A85 — 85 mL bottle

Pick the A200 when 200 mL is the workflow's specific working volume and bulk-prep throughput matters.
