The Z327-200-A100 is the 100 mL round-bottom glass 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 × 100 mL bottle; the 4-bucket rotor configuration takes 2 packs (4 inserts) for full symmetric loading, delivering 4 × 100 mL bottles per cycle (400 mL total) on the Z327-200 swing-out platform. 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) on this insert.

Compatibility & When to Order This SKU
Insert pairing — Z327-200-BUK swing-out bucket only. Order this SKU when:
- Adding 100 mL round-bottom bottle workflow to an existing Z327 / Z327-K + Z327-200 install — order 2 units for full 4-bucket symmetric loading (400 mL total per cycle).
- Mid-volume cell-prep, bioprocess, or environmental sample prep in 100 mL working volume.
- Optional cold-chain workflow on the Z327-K refrigerated chassis.
- Optional BSL-2 + workflow with the Z327-200-LID engaged for hermetic containment.
- Replacement inserts if a current set is damaged or worn.
Application Profile
4-bucket symmetric loading. All 4 buckets must use matching A100 inserts for symmetric balance.
Glass round-bottom bottle compatibility. The A100 envelope is dimensioned for the 40 mm OD × 95–115 mm length range — matches standard 100 mL round-bottom glass bottle formats. 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 on this insert.
Optional hermetic seal via LID. Compatible with the Z327-200-LID for BSL-2 + bottle workflows.
Design Architecture
Mid-volume cell harvest workflows — pelleting cells from 100 mL suspension culture batches; round-bottom glass supports protocols requiring glass for chemical compatibility or autoclave reuse.
Vaccine-development bioprocess prep — vaccine-development workflows that batch 4 × 100 mL bottles per cycle for intermediate concentration steps.
Cold-chain mid-volume bottle workflows on Z327-K — refrigerated 100 mL bottle workflows for cold-stable bioprocess intermediates.
Mid-volume protein-prep workflows — TCA, ammonium-sulfate, organic-precipitation in 100 mL working volume on the swing-out platform.
Environmental and analytical sample prep — water, soil-extract, sediment-supernatant prep at 100 mL bottle scale.
Cross-format Z327-K core facilities — labs running 100 mL alongside other bottle formats (85 mL A85, 200 mL A200) on the same Z327-200 + Z327-200-BUK inventory.
BSL-2 + bottle workflows — recombinant-protein expression and bioprocess prep handling genetically modified organisms in 100 mL bottle format with hermetic containment.
Ordering & Configuration
4-bucket symmetric loading. All 4 buckets must use matching A100 inserts. Mixed-bucket configurations produce mass asymmetry.
Bottle cap confirmation. All bottles must be capped securely before spinning at 5,000 rpm.
Bottle volume balance. When the 4 bottles carry different sample volumes, pre-balance pairs by total mass before spinning.
Z327-200-A100 ships as 2 inserts. Bottles (100 mL round-bottom glass) and the Z327-200-BUK bucket are sold separately. Z327-200-LID (optional, for hermetic mode) 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 (100 mL round-bottom glass, 40 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-A100 (this product) — 100 mL round-bottom glass
- Z327-200-A85 — 85 mL bottle (smaller mid-volume)
- Z327-200-A200 — 200 mL bottle (largest in this family)
Pick the A100 when 100 mL is the workflow's specific working volume; pick A85 or A200 for adjacent volumes.
