30 × 15 mL Angle Rotor

The Z326-3015 is the highest-throughput 15 mL rotor in the Hermle Z326 / Z32-HK rotor catalog — 30 positions per cycle for 15 mL tubes at 35° fixed-angle geometry. Where most 15 mL angle rotors in this class top out at 12 or fewer positions, the Z326-3015 packs 30 tubes into a single rotor body, making it the throughput-optimized pick for clinical-research, biobanking, and academic-core batch workflows that process 15 mL primary samples in volume. Direct fit for 15 mL Glass tubes (17 mm OD); the C3100-ADP adapter extends compatibility to 5–7 mL formats when smaller-volume work shares the same rotor body.

Key Specifications

Compatibility & Configuration

Chassis compatibility — Z326 family + cross-compatible Z32-HK per the shared Hermle accessory catalog. RFID-tagged; chassis applies the rotor's rated speed cap automatically at insertion.

30-position layout. Tubes are arranged radially around the rotor body in a high-density pattern; the 35° angle balances per-tube RCF efficiency with the geometric constraints of fitting 30 positions in a single rotor.

Direct fit for 15 mL Glass tubes (per the brochure adapter table — "without adapter 1 x 15 ml-Glass 17.0 95/115"). The 17 mm ø is the standard 15 mL glass-tube OD; standard 15 mL conical Falcon-style tubes are slightly different geometry and may require their own adapter — confirm tube fit at order if your workflow uses non-glass 15 mL formats.

C3100-ADP adapter (sold separately) — extends coverage to 5/7 mL tube formats. Supplied as a pack of 8 adapters per the brochure, allowing partial-rotor configurations (8 × 5/7 mL among the 30 positions) for mixed-volume batches. Note that for fully-loaded 30 × 5/7 mL operation, multiple adapter packs would be needed — confirm adapter quantity at order.

Application Profile

30 × 15 mL clinical batch workflows — the rotor's primary use case. Phlebotomy primary-tube batch processing, clinical-research serum/plasma separation at high per-cycle throughput, immunology and hematology batch sample preparation.

Biobanking aliquot preparation — when biobank workflows need to spin large batches of 15 mL primary samples for serum/plasma extraction before cryostorage, 30-tube parallel processing reduces total batch time.

Academic-core 15 mL workflow consolidation — multiple research groups' 15 mL samples can be processed in a single batch when scheduling permits.

Microbiology batch culture handling — 15 mL bacterial culture aliquots for sub-culturing, identification, or extraction prep at 30-tube throughput.

Mixed-volume batch via partial-adapter loading — when most of the workflow is 15 mL but some samples are 5/7 mL, the C3100-ADP adapter supports mixed-format batches (with attention to symmetric balance).

Cold-chain workflows on refrigerated chassis — when paired with Z326-K or Z032-HK, the rotor handles batch 15 mL processing at controlled temperature.

Loading & Balance

30-tube symmetric loading. With 30 positions, the load-balancing pattern requires distributing tubes symmetrically around the rotor — even with high position counts, the chassis's RFID-aware imbalance shut-off catches asymmetric loads. Pre-balancing remains operator responsibility; the high position count makes precise balancing more important, not less.

Mixed-adapter loading caution. If using the C3100-ADP adapter for partial loading, position the adapters symmetrically (8 adapters in opposing positions, 22 direct-fit 15 mL in the remaining positions, all balanced in mass-pairs).

Selectable accel/decel. The chassis's 10 acceleration / 10 deceleration profiles apply.

Ordering & Configuration

Z326-3015 ships as the rotor body alone. Adapters and any specialty tube formats are sold separately.

Compatible accessories (sold separately):

• C3100-ADP — 1 × 5/7 mL adapter (pack of 8); for partial-rotor mixed-format configurations

Confirm at quote: chassis pairing (Z326 family or Z032-HK), tube format (confirm 15 mL Glass 17 mm OD vs 15 mL conical Falcon-style fit), adapter quantity needed for any 5/7 mL workflow share, and lead time.

Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the rotor body. Balance validation through the Hermle service network — recommended at install plus annually for high-utilization environments.

Z326-3015 vs Z326-1215 selection: the Z326-3015 (this product, 30 positions) maximizes per-cycle throughput. The Z326-1215 (12 × 15 mL) is the lower-position-count alternative — fewer tubes per cycle but typically at higher RCF or with different adapter compatibility. For high-throughput clinical-research labs, the Z326-3015 is the throughput pick; for mid-throughput workflows where 12 tubes per cycle is sufficient, the Z326-1215 may be more economical.
