10 × 50 mL Conical Angle Rotor

The Z326-1050 is a 10-position fixed-angle rotor for 50 mL conical tubes in the Hermle Z326 / Z32-HK family — engineered around the 50 mL conical format for maximum per-cycle throughput at moderate RCF. At 9,000 rpm / 11,771 × g across 10 tubes per cycle, this rotor sits between the lower-RCF 6 × 50 mL options (Z326-0650-LS) and the high-RCF 6 × 50 mL options (Z326-0650-HS). The trade-off is per-tube g-force vs per-cycle throughput: with the Z326-1050, you process 67% more tubes per cycle than a 6-position rotor, at roughly half the maximum RCF the high-speed 6-position variant delivers.

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 9,000 rpm cap automatically at insertion.

50 mL conical direct fit. Standard 50 mL conical tubes (Falcon-style, Corning, Fisher, and other 29 mm OD conical formats) fit the rotor's 29 mm tube ø directly without adapter.

Adapter library for smaller-volume work (sold separately per the brochure adapter table for the Z326-1050):

• 1 × 15 mL RB (round-bottom) — 17 mm tube ø, 97/123 mm length
• 1 × 15 mL conical — 17 mm tube ø, 120 mm length
• 1 × 7 mL — 13.5 mm tube ø, 95/115 mm length
• 1 × 5 mL — 13.5 mm tube ø, 70/90 mm length

The adapter strategy makes the Z326-1050 a flexible "secondary" rotor for cores whose primary 50 mL workflow occasionally extends to 15 mL or 5–7 mL formats.

Application Profile

10 × 50 mL conical batch workflows — the rotor's primary use case. Cell-culture pellet recovery from 50 mL aliquots at 11,771 × g, post-extraction concentration in 50 mL conical, environmental sample particulate clearance at high per-cycle throughput.

Mid-RCF clinical-research workflows where 50 mL conical primary samples need 10-tube parallel processing at moderate RCF — between the standard low-speed clinical separation (3,000–5,000 × g) and the high-RCF protein-pelleting work (20,000+ × g).

Cold-chain protein workflows when paired with the refrigerated Z326-K or Z032-HK chassis. The rotor's −4 °C temperature-at-max-speed spec supports 4 °C cold-chain work.

Multi-format flexibility via adapters. When the workflow occasionally needs 15 mL or smaller-volume tubes alongside the dominant 50 mL conical work, the adapter library extends the rotor's coverage without requiring a second rotor purchase.

Loading & Balance

10-tube symmetric loading. With 10 positions, the load-balancing pattern is opposite-pair distributed across the rotor (positions 1+6, 2+7, 3+8, 4+9, 5+10). Pre-balance pairs by weight before insertion.

Adapter consistency required across all 10 positions when using adapters — mixed-adapter loading produces asymmetric mass distribution.

Selectable accel/decel. Chassis's 10 acceleration / 10 deceleration profiles apply. The unbraked decel (796 sec extended profile per brochure) supports loose-pellet and gradient-preservation work.

Ordering & Configuration

Z326-1050 ships as the rotor body alone. Adapters and any specialty tube formats are sold separately.

Confirm at quote: chassis pairing (Z326 family or Z032-HK), adapter inventory needed for smaller-volume tube formats, and lead time.

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

Z326-1050 vs Z326-0650 family selection: the Z326-1050 (this product, 10 positions / 11,771 × g) is the throughput-optimized 50 mL rotor — best when batch size matters more than per-tube RCF. The Z326-0650-HS (6 positions, 24,039 × g at 16,000 rpm) is the high-speed 50 mL pick — best when per-tube g-force drives the workflow. The Z326-0650-LS (6 positions, low speed) is the economy pick for routine low-RCF 50 mL work. Match the rotor to whether per-cycle throughput or per-tube g-force is the operative spec.
