100 mL Bottle Insert for Z366-250 Bucket (2/pk)

The Z366-250-A100 is the 100 mL bottle 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 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) in swing-out geometry on the deep cold-chain Z366-K chassis (−2 °C at max speed). The Z366-250 swing-out platform's near-freezing cold-chain capability distinguishes this 100 mL configuration from other Hermle 100 mL bottle workflows.

Key Specifications

Compatibility & When to Order This SKU

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

1. Adding 100 mL bottle workflow to an existing Z366 / Z366-K + Z366-250 install — order 2 units for full 4-bucket symmetric loading (400 mL total per cycle).
2. Deep cold-chain mid-volume bottle workflows — when the workflow needs the Z366-K's −2 °C cold-chain integrity for cold-stable analyte preservation.
3. Mid-volume cell-prep, bioprocess, or environmental sample prep in 100 mL working volume.
4. Replacement inserts if a current set is damaged or worn.

Why Deep Cold-Chain at 100 mL Matters

The Z366-K chassis's −2 °C at max speed is among the deepest cold-chain temperatures in the Hermle swing-out family — useful when 100 mL bottle workflows handle:

• Cold-stable analytes that need near-freezing preservation through the centrifugation step
• Some metabolomics and proteomics workflows where temperature stability through the spin step affects downstream analytical reproducibility
• Cold-chain biobank prep in 100 mL pooled sample format

Standard refrigerated chassis (Z327-K at 2 °C, Z326-K at 4 °C) are appropriate for most cold-chain workflows; the Z366-K's deeper cold-chain matters for the subset of workflows specifying near-freezing temperatures.

Application Profile

Deep cold-chain mid-volume cell harvest — pelleting cells from 100 mL suspension culture batches at near-freezing temperature for cold-stable analyte preservation.

Cold-chain bioprocess intermediate prep at 100 mL — vaccine-development and bioprocess workflows that batch 4 × 100 mL bottles per cycle with deep cold-chain integrity.

Mid-volume protein-prep workflows at near-freezing temperature — TCA, ammonium-sulfate, organic-precipitation in 100 mL working volume on the deep cold-chain platform.

Environmental and analytical sample prep at 100 mL — water, soil-extract, sediment-supernatant prep at 100 mL bottle scale for cold-chain analytical workflows.

Metabolomics and proteomics sample prep — when the workflow specifies near-freezing temperature stability through the centrifugation step.

Cross-format Z366-K core facilities — labs running 100 mL bottle alongside other tube and bottle formats on the same Z366-250 swing-out platform.

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 4,500 rpm.

Bottle volume balance. When the 4 bottles carry different sample volumes, pre-balance pairs by total mass before spinning.

Z366-250-A100 ships as 2 inserts. Bottles (100 mL, 41 mm OD) and the Z366-250 bucket are sold separately.

Confirm at quote: bucket pairing (Z366-250 in inventory), chassis pairing (Z366 or Z366-K), bottle format (100 mL, 41 mm OD), pack count (2 packs for full 4-bucket configuration), cold-chain requirement (Z366-K for near-freezing), and lead time.

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

Z366-250 bottle-insert family (Z366 / Z366-K chassis):

- Z366-250-A100 (this product) — 100 mL bottle

- Z366-250-A250 — 250 mL flat bottle (largest in family)

Pick the A100 when 100 mL is the workflow's working volume; pick A250 for larger bottle workflows on the same swing-out platform.
