48 × 2.6–8 mL Vacutainer Insert for Z496-1000-RBUK (2/pk)

The Z496-1000-A57 is the 48 × 2.6–8 mL Vacutainer-style tube insert for the Hermle Z496-1000-RBUK rectangular bucket — sold as a 2-pack. With the full 4-bucket configuration, the rotor processes 192 × 2.6–8 mL Vacutainer tubes per cycle — the highest tube-count-per-cycle in the entire Hermle catalog. The 5 mL and 7 mL Vacutainer formats cover small-volume clinical primary samples (pediatric collection, capillary collection, low-volume research draws); 192-tube parallel throughput delivers reference-laboratory-scale processing on a single Z496-K cycle.

Key Specifications

Compatibility & Configuration

Insert pairing — Z496-1000-RBUK rectangular bucket only.

192-tube parallel throughput. This is the highest single-cycle throughput available in the Hermle catalog for any tube format. Reference-laboratory-scale clinical-research workflows that previously required multiple cycles on smaller chassis can be consolidated to single Z496-K cycles.

5 mL and 7 mL Vacutainer compatibility. The same insert position accepts both common Vacutainer sizes — useful for clinical-research labs whose phlebotomy mix includes both 5 mL and 7 mL primary tubes.

Reference-lab and high-throughput clinical workflows — when batch sizes routinely exceed 100 small-volume Vacutainer primary tubes per session, this insert + Z496-K combination eliminates multi-cycle processing time.

Pediatric and capillary-collection workflows that use 5 mL Vacutainer formats benefit from the per-cycle throughput at this tube size.

Cold-chain Vacutainer workflows on Z496-K — combines the 192-tube throughput with chassis refrigeration.

Ordering & Configuration

Z496-1000-A57 ships as 2 inserts. 2.6–8 mL Vacutainer tubes are operator-supplied (commodity clinical supplies).

Confirm rectangular-bucket inventory, rotor-body pairing, and insert count at quote.

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

2.6–8 mL workflow throughput across the Hermle catalog:

- Smaller chassis 2.6–8 mL rotors typically deliver 6–12 tubes per cycle

- Z496-1000-A57 (this product) delivers 192 tubes per cycle on Z496-K chassis

The throughput-per-cycle delta is meaningful for high-volume clinical-research labs — typically 15–20× single-cycle throughput vs benchtop alternatives.
