The Z287-2420 is the 24-position fixed-angle microtube rotor for the Hermle Z287-A compact universal centrifuge — the higher-throughput sister to the Z287-1820 (18-position) microtube rotor. At 12,000 rpm / 13,683 × g, the rotor delivers high-RCF microtube capability across 24 parallel positions per cycle, sized for institutional clinical-research and core-facility microtube workflows where batch size matters as much as RCF. Z287-A only — engineered for the Z287-A spindle.

Compatibility & Configuration
Chassis compatibility — Z287-A family. Engineered for the Z287-A compact universal centrifuge spindle and chamber.
24-position throughput. The 24-position layout matches:
- 1/4 of a 96-well plate batch (24 = 1/4 plate quadrant)
- A typical extraction-kit batch size (most commercial DNA/RNA kits are sized for 24-sample batches)
- Common qPCR and assay-prep batch sizes for institutional clinical-research workflows
RCF / throughput trade-off vs Z287-1820. Choose between higher RCF (Z287-1820 at 15,994 × g, 18 positions) and higher throughput (Z287-2420 at 13,683 × g, 24 positions) based on workflow priority — both rotors fit the same Z287-A chassis and can be swapped between protocol steps when both characteristics are needed.
Adapter library. The standard C1008 adapter family (cross-compatible across multiple Hermle chassis) supports 0.5 mL and 0.4 / 0.2 mL PCR formats within the 1.5 / 2.0 mL position.
Application Profile
Institutional extraction-kit workflows — DNA, RNA, plasmid prep at 24-sample-per-cycle throughput on the Z287-A chassis.
Cell-pellet recovery at moderate-high RCF — bacterial culture pellets, mammalian cell pellets, organelle prep at 13,683 × g — sufficient for most routine cell-prep protocols.
Clinical-research aliquot prep — patient sample aliquoting into 1.5 / 2.0 mL microtubes for cryostorage and analytical batch shipping at 24 samples per cycle.
Mixed-workflow Z287-A consolidation — when one Z287-A serves both clinical-research 50 mL workflows (Z287-0450H), 15 mL workflows (Z287-0815), and high-throughput microtube workflows (this Z287-2420), the chassis serves multiple workflow types via rotor swap.
Educational and training labs — undergraduate and graduate teaching where 24 sample positions match standard teaching-block sizes.
Loading & Balance
24-position symmetric loading. Pair opposites (positions 1+13, 2+14, etc.) by tube mass.
Adapter symmetry. When using C1008 adapters, paired positions must use matching adapter + tube combinations.
Tube cap confirmation. All tubes must be securely capped before spinning at 12,000 rpm.
Selectable accel/decel. Z287-A chassis profiles apply; the unbraked extended-decel profile (208 sec) preserves loose pellets and density layers.
Ordering & Configuration
Z287-2420 ships as the rotor body alone. Adapters (C1008-A5-6, C1008-A2-6) for smaller-volume tubes are sold separately.
Confirm at quote: chassis pairing (Z287-A confirmed), throughput vs RCF preference (vs Z287-1820), adapter inventory for smaller-volume formats, and lead time.
Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the rotor body.
Z287-A microtube rotor selection:
- Z287-2420 (this product) — 24 × 1.5 / 2.0 mL at 13,683 × g for 24-position throughput
- Z287-1820 — 18 × 1.5 / 2.0 mL at 15,994 × g for higher RCF at smaller batch
- Z287-24SC — 24 × 2.0 mL spin column rotor for extraction-kit workflows
- Z287-3202 — 4 × 8 PCR-strip rotor for PCR setup and cleanup
Pick the 2420 for institutional 24-batch throughput; pick the 1820 when RCF matters more than batch size.
