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

The Z327-200-A85 is the 85 mL round-bottom 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 × 85 mL bottle; the 4-bucket rotor configuration takes 2 packs (4 inserts) for full symmetric loading, delivering 4 × 85 mL bottles per cycle (340 mL total) in swing-out geometry. The 85 mL format sits in the mid-volume bottle workflow range, between the 50 mL conical/round inserts (A50, A50R) and the larger 100 mL bottle insert (A100).

Key Specifications

Compatibility & When to Order This SKU

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

1. Adding 85 mL bottle workflow to an existing Z327 / Z327-K + Z327-200 install. Order 2 units for full 4-bucket symmetric loading (340 mL total per cycle).
2. Mid-volume bioprocess prep at 85 mL: vaccine-development and bioprocess workflows that batch 85 mL bottles for intermediate concentration steps.
3. Optional cold-chain workflow on the Z327-K refrigerated chassis.
4. Optional BSL-2 + workflow with the Z327-200-LID engaged for hermetic containment.
5. Replacement inserts if a current set is damaged or worn.

Application Profile

4-bucket symmetric loading. All 4 buckets must use matching A85 inserts for symmetric balance.

Bottle format precision. The A85 envelope is dimensioned for the 38 mm OD × 116 mm length range. Bottles outside this dimensional range may not seat properly; verify dimensions if using non-standard bottle suppliers.

Mid-volume position in the bottle insert family. The A85 sits between the smaller A50 / A50R (50 mL) and the larger A100 (100 mL) bottle inserts. The right pick when 85 mL is the workflow's specific intermediate volume.

Optional hermetic seal via LID. Compatible with the Z327-200-LID for BSL-2 + 85 mL bottle workflows.

Design Architecture

Mid-volume cell harvest workflows. Pelleting cells from 85 mL suspension culture batches at 4 bottles per cycle on the swing-out chassis.

Bioprocess intermediate prep at 85 mL: vaccine-development workflows that use 85 mL bottles as the intermediate concentration step between smaller (50 mL) and larger (100 mL) volumes.

Cold-chain mid-volume bottle workflows on Z327-K: refrigerated 85 mL bottle workflows for cold-stable bioprocess intermediates.

Mid-volume protein-prep workflows. TCA, ammonium-sulfate, organic-precipitation in 85 mL working volume on the swing-out platform.

BSL-2 + bioprocess prep at 85 mL: recombinant-protein expression and bioprocess prep handling genetically modified organisms in 85 mL bottle format with hermetic containment.

Cross-format Z327-K core facilities: labs running 85 mL bottle alongside other tube and bottle formats benefit from stocking the cross-format Z327-200 insert family.

Ordering & Configuration

4-bucket symmetric loading. All 4 buckets must use matching A85 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.

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.

Z327-200-A85 ships as 2 inserts. Bottles (85 mL round-bottom) 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 (85 mL round-bottom, 38 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 bottle-insert family (Z327 / Z327-K chassis):

- Z327-200-A85 (this product): 85 mL bottle (mid-volume)

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

- Z327-200-A200: 200 mL bottle (largest in family)

- Z327-200-A50 / A50R / A50SS: 50 mL variants (smaller mid-volume)

Pick the A85 when 85 mL is the workflow's specific working volume.
