12 × 15 mL Angle Rotor

The Z326-1215 is the mid-throughput 15 mL angle rotor in the Hermle Z326 / Z32-HK rotor catalog — 12-position fixed-angle at 32° angle. Sits between the high-throughput Z326-3015 (30 × 15 mL) and dedicated single-tube workflows; appropriate for labs whose 15 mL workflow batches at 12 tubes per cycle and doesn't justify the larger 30-position rotor's higher price point or footprint. Direct fit for both 15 mL Falcon-style conical tubes and 15 mL Universal tubes; smaller-volume work via the C3100-ADP adapter.

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.

12-tube parallel processing. A typical clinical-research batch (1 phlebotomy session = 6–8 primary samples × 1–2 aliquots each = 6–16 tubes) fits in one or two cycles of the Z326-1215. Where the Z326-3015 (30 positions) would over-cycle a small batch, the Z326-1215 matches typical batch sizes without rotor over-spec.

Direct fit for both Falcon-style and 15 mL Universal formats — the rotor's 17 mm tube ø position accepts both common 15 mL clinical-research tube formats without adapter swap.

Smaller-volume workflows via C3100-ADP — when the workflow extends to 5 mL or 7 mL Vacutainer formats, the C3100-ADP adapter (sold separately, pack of 8) supports them on the same rotor body.

Application Profile

Mid-throughput clinical-research 15 mL workflows — serum/plasma separation, cell-pellet recovery, microbiology batch culture handling at 12-tube parallel throughput.

Small-batch academic-research labs where 12 tubes per cycle matches typical experimental batch sizes.

Method-development workflows that compare across 12 sample variations under identical conditions in a single cycle.

Mixed-format batches when the workflow occasionally extends from 15 mL down to 5/7 mL via adapter loading.

Ordering & Configuration

12-tube symmetric loading. Opposite-pair distribution (1+7, 2+8, etc.); pre-balance pairs by weight before insertion.

Z326-1215 ships as the rotor body alone. C3100-ADP adapter sold separately if smaller-volume workflows share the rotor.

Confirm at quote: chassis pairing (Z326 family or Z032-HK), adapter quantity if needed, training, lead time.

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

15 mL rotor selection within the Z326 catalog: the Z326-1215 (this product, 12 × 15 mL) is the mid-throughput pick. The Z326-3015 (30 × 15 mL) is the high-throughput alternative for cores batching 30+ tubes per cycle. Pick based on whether 12-tube or 30-tube cycle throughput matches your workflow batch size.
