200 mL Round Bucket for Z327-200-AC (2/pk)

The Z327-200-BUK is the 200 mL round bucket that pairs with the Hermle Z327-200-AC swing-out rotor body on the Z327 / Z327-K chassis — sold as a 2-pack. The Z327-200-AC rotor body holds 4 buckets, so a complete 4-bucket configuration requires 2 units of Z327-200-BUK (4 buckets total). The BUK accepts the full Z327-200-A* insert family — 14 distinct insert variants spanning microtubes through 200 mL bottles. When paired with the Z327-200-LID (sold separately), the bucket creates a hermetic envelope for BSL-2 + workflows; the LID is optional for non-biosafety workflows.

Key Specifications

Compatibility & When to Order This SKU

This SKU is the bucket only. Order Z327-200-BUK when at least one of the following applies:

1. Commissioning a Z327-200-AC rotor body — order 2 units for a complete 4-bucket configuration. Plus Z327-200-A* inserts for the workflow's tube/bottle format. Plus Z327-200-LID (optional, one per bucket = 4 lids for full hermetic capability).
2. Adding bucket capability to an existing Z327 / Z327-K install with a different rotor configuration.
3. Replacement buckets if a current set is damaged or has reached service life.
4. Spare bucket inventory for facilities running mixed BSL-2 / non-BSL-2 workflows that benefit from rotating bucket sets through cleaning and decontamination cycles between sample types.

Z327-200 Rotor System Position in the Z327 Chassis Catalog

The Z327 / Z327-K chassis family supports multiple swing-out rotor systems with different RCF ranges and biosafety capabilities:

The Z327-200 + Z327-200-BUK combination delivers swing-out 4-place workflows with the broadest insert family (14 variants) and optional hermetic-seal capability — useful when one chassis must serve many workflow formats including some biosafety workflows.

Application Profile

4-bucket symmetric loading. All 4 buckets must be installed for symmetric balance at 5,000 rpm.

Insert selection. Each bucket accepts one insert from the Z327-200-A* family for the workflow's tube/bottle format. All 4 buckets must use matching inserts for symmetric balance.

Optional hermetic seal via LID. When combined with the Z327-200-LID (one per bucket = 4 lids total), the buckets create hermetic envelopes for BSL-2 + workflows. The LID is optional — for non-biosafety workflows, the buckets run without lids.

Lid-compatible vs non-lid-compatible inserts. Most Z327-200-A* inserts are lid-compatible (A10, A15, A20, A25, A30, A50, A50R, A50SS, A57, A5F, A85, A100, A200). Two variants are non-lid-compatible (A15B, B50 — both marked "* only without bucket lid" in the brochure).

Design Architecture

Mixed-format clinical-research and biobank workflows on Z327 / Z327-K — labs that handle multiple tube and bottle formats on the same chassis benefit from the Z327-200 system's 14-insert family (vs more limited insert families on other Z327 swing-out rotor systems).

Cold-chain swing-out workflows — refrigerated cell-prep, density-gradient prep, biobank aliquot prep across multiple tube formats on the Z327-K refrigerated chassis.

Optional BSL-2 + workflows — when some workflows on the chassis need biosafety containment and others don't, the BUK + LID combination supports both modes (LID engaged for biosafety; LID removed for non-biosafety).

Institutional clinical-blood-component prep — hospital reference labs and clinical-research recruitment workflows that batch many patient samples per cycle.

Mid-volume bioprocess prep — vaccine-development, recombinant-protein, cell-culture workflows that batch 50 mL through 200 mL volumes per cycle.

Cross-format Z327-K core facilities — shared cores supporting researchers across multiple tube/bottle workflows benefit from the broad insert family.

Ordering & Configuration

4-bucket symmetric loading is mandatory; insert configurations across the 4 buckets must match for symmetric balance.

Optional hermetic-seal engagement. Per Hermle service instructions, when using the Z327-200-LID, the lid must be fully engaged on each bucket before each spin to maintain the hermetic envelope at 4,136 × g.

Z327-200-BUK ships as 2 buckets — no rotor body, no inserts, no lids.

Required for operation:

• Z327-200-AC rotor body (sold separately) or already in inventory
• For full 4-bucket configuration: order 2 units of this SKU
• Z327-200-A* inserts (sold separately) for the workflow's specific tube/bottle format
• Z327-200-LID (optional, sold separately — 4 lids needed for full hermetic configuration)

Confirm at quote: rotor-body pairing (existing Z327-200-AC inventory or new rotor-body order), bucket count (2 or 4), insert family needed for intended tube/bottle formats, optional LID count for biosafety workflows, and lead time.

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

Z327-200 rotor system procurement summary (Z327 / Z327-K chassis):

- Z327-200-AC (rotor body, sold separately) + 2 × Z327-200-BUK (4 buckets) = base swing-out configuration

- Add Z327-200-A* insert SKUs for the workflow's tube/bottle format (14 variants available)

- Add 4 × Z327-200-LID for hermetic-seal capability when biosafety workflows are part of the protocol

- Or use direct-fit Z327-200-B50 buckets (replaces BUK + A50 insert) when 50 mL conical workflow needs higher non-sealable throughput
