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 — 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
