Hermetically Sealed Lids for Z327-200-BUK (2/pk)

The Z327-200-LID is the hermetically sealed lid for the Hermle Z327-200-BUK round bucket on the Z327 / Z327-K chassis 4-place swing-out rotor — sold as a 2-pack. The lid engages the bucket's hermetic-seal mode for BSL-2 + biosafety workflows: when fully engaged on the bucket, the lid creates an aerosol-tight envelope around the tube load. The Z327-200 rotor takes 4 buckets × 1 lid each = 4 lids total for full hermetic configuration — buyer needs 2 packs of this SKU. The lid is the separate purchase that activates biosafety mode on the Z327-200 rotor system; without the lid, the BUK runs in non-sealable mode.

Key Specifications

Compatibility & When to Order This SKU

This SKU activates hermetic-seal capability on the Z327-200-BUK bucket. Order Z327-200-LID when at least one of the following applies:

1. Commissioning a Z327-200 hermetic-seal configuration — order 2 units for full 4-bucket hermetic capability (4 lids).
2. Adding biosafety capability to an existing Z327 / Z327-K + Z327-200 install that currently runs in non-sealable mode — switching the workflow into BSL-2 + biosafety requires the lid set.
3. BSL-2 + clinical workflows — clinical and clinical-research workflows handling potentially infectious patient samples (HIV research, hepatitis, TB, respiratory pathogens) where the chain of containment must be maintained from biosafety cabinet through centrifugation back to cabinet.
4. Replacement lids if a current set is damaged, the seal interface has worn, or the lids have reached service life.
5. Spare lid inventory for facilities running mixed BSL-2 / non-BSL-2 workflows that benefit from rotating lid sets through cleaning and decontamination cycles.

Why a Separate-Purchase Lid Matters

Most hermetic-seal centrifuge bucket systems include the lid as part of the bucket SKU. The Z327-200 system separates the bucket and lid into two SKUs — useful for several procurement patterns:

• Non-biosafety initial configuration, biosafety added later. Labs that initially commission the Z327-200 rotor for non-biosafety workflows can defer the lid purchase and add it later when biosafety workflows enter the protocol mix.
• Lid replacement without bucket replacement. The lid's seal interface is the wear item; the lid can be replaced when the seal degrades without replacing the bucket.
• Spare lid inventory for decontamination cycles. Facilities running rigorous biosafety decontamination protocols can rotate lid sets through cleaning while keeping the buckets in service.

Lid-Compatible vs Non-Lid-Compatible Inserts

The Z327-200 insert family splits into two compatibility classes:

When using non-lid-compatible inserts (A15B) or direct-fit buckets (B50), the Z327-200-LID is removed — those configurations are for higher non-sealed throughput. Confirm insert compatibility with the lid at order.

Application Profile

Cold-chain BSL-2 + clinical-blood-component prep at institutional scale — hospital and clinical-research labs requiring both refrigeration (Z327-K chassis) and biosafety containment for routine clinical-blood prep workflows.

Clinical-research infectious-disease cohort prep — patient sample prep workflows for infectious-disease research requiring containment from collection through cryostorage.

Biobank intake workflows handling potentially infectious specimens — biobank prep for clinical-research studies that include BSL-2 + sample types.

Recombinant-protein and bioprocess prep at BSL-2 — recombinant-protein expression workflows handling genetically modified organisms in bottle or tube format with required aerosol containment.

Cross-format BSL-2 Z327-K core facilities — shared cores running mixed BSL-2 workflows across multiple tube formats benefit from the lid-engaged sealable configuration with the broad Z327-200-A* lid-compatible insert family.

Ordering & Configuration

Hermetic-seal engagement. Per Hermle service instructions, the Z327-200-LID must be fully engaged on each bucket before each spin to maintain the hermetic envelope at 4,136 × g. Partial lid engagement does not maintain seal integrity.

Lid-insert compatibility verification. Before installing the lid, confirm the bucket's insert is in the lid-compatible class (most Z327-200-A* inserts are lid-compatible; A15B and B50 are not).

Z327-200-LID ships as 2 lids.

Required for operation:

• Z327-200-BUK buckets (sold separately) — 4 buckets = 2 packs of BUK
• Z327-200-AC rotor body (sold separately) or already in inventory
• For full 4-bucket hermetic configuration: 2 units of this LID SKU

Confirm at quote: bucket pairing (Z327-200-BUK in inventory), chassis pairing (Z327 or Z327-K), insert family (confirm lid-compatible insert SKUs in inventory), lid count needed (2 packs for full 4-bucket configuration), workflow biosafety driver, and lead time.

Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the lids. The hermetic-seal interface is a planned-inspection item for biosafety workflows — Hermle's standard service interval recommendation includes the seal-integrity check.

Z327-200 hermetic-seal procurement summary:

- Z327-200-LID (this product) — 2 lids; buyer needs 2 packs (4 lids) for full 4-bucket hermetic configuration

- Z327-200-BUK — buckets that the lid engages (sold separately)

- Z327-200-AC — rotor body (sold separately)

- Lid-compatible Z327-200-A* inserts for the workflow's tube/bottle format

The lid is the SKU that activates BSL-2 + biosafety mode — without it, the Z327-200-BUK runs non-sealed.
