4 × 200 mL Swing-Out Rotor with Buckets (Z327 Accessory)

The Z327-200 is the standard swing-out rotor for the Hermle Z327 / Z327-K family, 4 × 200 mL bottle capacity in swing-out geometry, shipped with 4 buckets included. At full operating speed the buckets swing horizontal, producing the clean phase boundary required for serum/plasma separation, density-gradient work, and any workflow where vertical orientation would compromise the separation. The rotor's defining feature is its deep adapter library, the 200 mL buckets accommodate adapters that scale down to 1.5 / 2.0 mL micro tubes via the appropriate Z327-200-A* insert, making one swing-out rotor the workflow tool for everything from primary blood-collection bottles down to microtubes on the same chassis.

Key Specifications

Compatibility & Configuration

Chassis compatibility: Z327 family only. The Z327-200 fits the Z327 / Z327-K. Not interchangeable with Z366, Z446, Z032-HK, or smaller universal centrifuge chassis.

RFID-tagged. The Z327-200 carries an RFID tag that the chassis reads at insertion; the drive automatically applies the rotor's rated 5,000 rpm cap and tunes the per-rotor imbalance threshold. This is important on the Z327 chassis whose chassis-spec maximum is 18,000 rpm, without the per-rotor RFID cap, an operator could enter a higher speed than the swing-out rotor is rated for.

Without-buckets sister: Z327-200-AC ships the same rotor body without the 4 buckets, for facilities that already own buckets or are configuring custom bucket sets.

Bucket lid (Z327-200-LID, sold separately). Adds hermetically sealed bucket configuration for biosafety-critical separations where aerosol containment matters. The lid attaches to the bucket and seals during the spin.

Deep adapter library (sold separately, all in the Z327-200-A* SKU family). The adapters scale the 200 mL buckets down across the full tube range: A200 (1 × 200 mL conical, 56 mm ø; some 200 mL bottle formats are conical and need this adapter), A100 (1 × 100 mL RB glass, 40 mm), and A85 (1 × 85 mL RB/OR, 38 mm) for large formats; A50R / A50 / A50SS for 50 mL round, conical, and skirted tubes; A25 / A30 for 25–30 mL; A15 / A57 / A5F for 15 mL, 5–7 mL, and 5 mL; and A20 / A10 for micro and small tubes (1.5/2.0 mL up to ~10 mL).

The brochure tube-rack table specifies tube count per bucket per adapter, the 4-position rotor with appropriate adapters scales to high-throughput (e.g., 32 × 1.5/2.0 mL microtubes per cycle via the A20 adapter).

Application Profile

Primary 200 mL bottle separation: the rotor's primary use case. Bottle-format serum/plasma separation, cell-pellet recovery from 200 mL spinner-flask cultures, density-gradient work in 200 mL bottles.

High-throughput tube workflows via adapters. The 32-tube microtube configuration (via A20 adapter) gives the Z327 chassis batch-microcentrifuge throughput in a swing-out geometry, useful for clinical-research workflows that need the swing-out boundary clarity at higher per-cycle tube count.

Density-gradient work with the unbraked deceleration option (387 sec extended profile per brochure) preserving continuous gradients during slow-down.

Cold-chain swing-out separations when mounted on the refrigerated Z327-K, combines 200 mL bottle capacity with chamber temperature control for cold-sensitive proteins, vaccine concentration work, and similar cold-chain workflows.

Biosafety-critical separations when paired with the Z327-200-LID hermetically sealed bucket lid, important for blood-borne pathogen work, BSL-2/3 clinical samples, and aerosol-generating sample types.

Loading & Balance

4-bucket symmetric loading. Pair opposite buckets by weight (positions 1+3, 2+4); pre-balance to within the rotor's per-position tolerance.

Adapter consistency across the 4 buckets when using adapters. Mixed-adapter loading produces asymmetric mass distribution.

Selectable accel/decel. The chassis's 10 profiles apply; 387 sec extended decel preserves loose pellets and gradients.

Ordering & Configuration

Z327-200 ships as the rotor body PLUS 4 buckets: the standard swing-out configuration ready to operate. Adapters, bucket lids, and specialty inserts are sold separately.

Compatible accessories (sold separately):

• Z327-200-AC: same rotor body without buckets (for replacement / custom bucket configurations)
• Z327-200-BUK: individual bucket (for replacement or supplementation)
• Z327-200-LID: bucket lid for hermetically sealed configuration
• Z327-200-A* adapter family: covers 100 mL down to 1.5/2.0 mL formats

Confirm at quote: chassis pairing (Z327 / Z327-K), adapter inventory needed, whether bucket lids for sealed-spin biosafety work are part of the order, and lead time.

Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the rotor body and buckets. Balance validation through the Hermle service network.

Z327-200 vs Z327-200-AC selection: if you're commissioning a new Z327 install or don't already have compatible buckets, order Z327-200 (this product). The bundled rotor + 4 buckets is the single-line procurement path. Order Z327-200-AC when you already have buckets in inventory or are sourcing sealed-bucket configurations as separate line items.
