The Z366 is a 6-place / 250 mL universal centrifuge that occupies the high end of the Hermle benchtop line — capable of swing-out runs at 15,000 rpm / 21,379 × g and angle-rotor runs at 16,000 rpm / 24,325 × g, with bottle capacity of 6 × 250 mL. This is the spec for protein-prep groups, vaccine and biotherapeutic process labs, and academic cores that need to spin large-volume preparations at high RCF without committing to a floor-standing instrument.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Application Profile
Recombinant-protein prep. 6 × 250 mL bottle capacity at 24,325 × g handles E. coli pellet recovery, inclusion-body wash, and post-lysis debris pelleting in production-scale academic and biotech labs.
Vaccine and viral-prep concentration. Swing-out geometry and 250 mL bottle capacity support sucrose-cushion and step-gradient virus concentration without a dedicated ultracentrifuge for every workflow.
Sediment, particulate, and effluent science. Environmental and water-quality labs need 250 mL-class bottle capacity with consistent swing-out boundaries; the Z366's adapter library covers down to 1.5 / 2.0 mL micro tubes.
Industrial QC. Crude-oil water content (ASTM D96 / D4007), lubricant analysis, and slurry-density work routinely call for 250 mL-class bottles at 3,000–5,000 × g.
Multi-use academic core. With angle-rotor swap, the Z366 covers high-RCF microtube and 50 mL conical work; with the swing-out, it shifts to bottle-format prep — one instrument, two workflow profiles.
Design Architecture
RFID rotor identification with per-rotor over-speed protection. Each rotor in the Z366 family carries an RFID tag; the drive applies the rotor's rated speed cap automatically.
Active imbalance identification with rotor-specific cut-off. Per-rotor imbalance thresholds; asymmetric loading or mid-spin failure triggers automatic shutdown.
Motor-driven lid lock with safety interlock. Hard interlock; the lid cannot unlock during a run.
Maintenance-free induction motor. No brush wear; designed for daily institutional duty.
Microprocessor with one-handed touch operation. Splash-proof foil keypad; large LCD with simultaneous set / actual display for speed, RCF, and time.
Selectable accel/decel with unbraked deceleration option. Audible run-end alert with melody-selection options.
Optimized airflow keeps the chamber near ambient during long runs in this non-refrigerated model. (For active temperature control, see the Z366-K.)
Stainless-steel sample chamber for spill containment and chemical resistance.
Quick rotor exchange via single-spindle wing-nut lift-off; rotor identity flows automatically via RFID after swap.
Ordering & Configuration
Ships without rotor. The Z366 body ships with operator's manual and power cord. Select your rotor from the Z366 rotor catalog (linked from this page) — common configurations include the 6 × 250 mL swing-out (with adapter library down to micro tubes), 6 × 85 mL high-speed angle rotor, 16 × 50 mL fixed-angle, and 24 × microtube high-RCF options.
Voltage variants: The 230 V / 50-60 Hz model is available by special order.
Refrigerated upgrade path: Z366-K — same chassis with -20 °C to +40 °C refrigeration. Same rotor catalog, deeper chassis, higher power input.
Step-up: Z446 for 4 × 750 mL bottle capacity at the same 16,000 rpm class. Z496-K for high-volume 4 × 1,000 mL floor-standing work.
Warranty & service: 5-Year Hermle warranty (3 years full + 2 years drivetrain). Rotor validation, balance checks, RFID-rotor service, and North American support available through the Benchmark / Hermle distributor network.
Frequently Asked Questions
What is the maximum speed and RCF of the Z366? 15,000 rpm / 21,379 × g in swing-out; 16,000 rpm / 24,325 × g with an angle rotor.
What is the Z366's bottle capacity? 6 × 250 mL, with an adapter library down to 1.5/2.0 mL microtubes.
Is a refrigerated version available? Yes — the Z366-K adds −20 °C to +40 °C refrigeration on the same chassis and rotor catalog.
Does the Z366 ship with a rotor? No — select from the Z366 rotor catalog (6 × 250 mL swing-out, 6 × 85 mL angle, 16 × 50 mL fixed-angle, 24 × microtube).
What voltage does the Z366 use? 120 V / 50–60 Hz standard; a 230 V / 50–60 Hz model is available by special order.
