1,000 mL Round Bucket for Z496-1000-AC (2/pk)

The Z496-1000-1L is the round bucket that pairs with the Z496-1000-AC swing-out rotor body, sold as a 2-pack. The complete Z496 swing-out rotor takes 4 buckets, so a full bucket set requires 2 units of Z496-1000-1L (4 buckets total). The "1L" suffix denotes the 1-liter (1,000 mL) bucket envelope. The defining characteristic vs the rectangular sister bucket (Z496-1000-RBUK) is higher max RCF, the round bucket's longer max radius (22 cm vs the rectangular's 20.1 cm) delivers 5,203 × g vs 3,964 × g at the bucket's max operating speed. For tube-format and bottle-format workflows that need maximum RCF in the Z496-K family, the round bucket is the spec.

Key Specifications

Compatibility & When to Order This SKU

This SKU is the round bucket only. Order Z496-1000-1L when at least one of the following applies:

1. You're commissioning a Z496-1000-AC (rotor body without buckets) and need round buckets for tube/bottle workflows. Order 2 units for a complete 4-bucket configuration.
2. You're adding round-bucket capability to an existing Z496-K install that currently uses rectangular Z496-1000-RBUK microplate buckets. It supports tube/bottle workflows alongside microplate-format work without rotor-body swap.
3. Replacement round buckets if a current set is damaged or has reached service life.
4. Spare bucket inventory for facilities running mixed-product or biosafety workflows that benefit from rotating bucket sets through cleaning cycles.

Round vs Rectangular Bucket Selection

The Z496-K rotor body (Z496-1000-AC) supports two bucket profiles. The selection depends on workflow:

Round buckets reach higher RCF because the longer max radius geometry delivers more RCF per RPM. The trade-off: round buckets don't accept microplates directly, microplate workflows require an adapter or the rectangular bucket alternative.

Mixing bucket profiles is not supported. All 4 positions on the rotor must use the same bucket type for symmetric balance. Facilities running both tube/bottle and microplate workflows often own both bucket types and swap full bucket sets between protocols.

Application Profile

4 × 1,000 mL bottle workflows at maximum RCF. The round bucket's primary use case. Production-scale cell harvest at 5,203 × g, vaccine concentration at maximum Z496-K RCF, environmental high-volume processing where the higher RCF justifies the round-bucket choice over rectangular.

Tube-format high-throughput workflows via Z496 adapter library: when the workflow needs 50 mL conical or 15 mL conical at higher RCF than the rectangular bucket's microplate-direct geometry delivers.

Cold-chain bottle workflows on Z496-K / Z496-K-UC: combines the round bucket's higher RCF with the chassis's −20 °C to +40 °C temperature control.

Bulk plasma and blood-component preparation at 1,000 mL bag-format scale where the higher RCF supports faster phase separation.

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. At the round bucket's 22 cm max radius, balance precision matters, small mass imbalances translate to substantial inertial asymmetry at 4,600 rpm.

Adapter consistency when using adapters across all 4 buckets.

Selectable accel/decel. Chassis's profiles apply; the unbraked decel (1,067 sec extended profile) preserves loose pellets and gradients.

Ordering & Configuration

Z496-1000-1L ships as 2 round buckets: no rotor body, no inserts, no adapters.

Required for operation:

• Z496-1000-AC rotor body (sold separately) or already in inventory
• For full 4-bucket configuration: order 2 units of this SKU
• For specific tube-format workflows: appropriate adapter inserts (sold separately)

Confirm at quote: rotor-body pairing (existing Z496-1000-AC inventory or new rotor body order), bucket count needed (2 or 4), adapter inserts needed for intended tube formats, and lead time.

Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the buckets. Includes manufacturing defect coverage; bucket service-life inspection is part of the standard Hermle service interval recommendation.

Z496-K bucket procurement summary:

- Z496-1000 ($8,925), Bundled rotor + 4 buckets, single-line procurement for a new install

- Z496-1000-AC ($4,872) + 2 × Z496-1000-1L ($3,474 for 4 round buckets) = $8,346, separate-line procurement for round-bucket configuration

- Z496-1000-AC + 2 × Z496-1000-RBUK ($5,386 for 4 rectangular buckets) = $10,258, for microplate-direct workflows

- Z496-1000-1L alone ($1,737, 2 buckets): replacement or supplementation
