The Z327 is a high-speed universal centrifuge that runs to 18,000 rpm / 23,542 × g and accommodates 4 × 200 mL bottles in its swing-out configuration. It is the Hermle answer for labs whose workflows span the gap between microcentrifuge-class g-force and bottle-format volume, pharmaceutical formulation labs, vaccine and protein-production groups, environmental and forensic laboratories, and academic cores that don't want to maintain separate high-speed and universal instruments. RFID rotor identification, a stainless-steel chamber, and Hermle's induction-drive build make this a long-service-life institutional purchase.

Application Profile
Pharmaceutical formulation and stability. 18,000 rpm covers pelleting of fine-particulate suspensions and post-emulsion phase separation; the 4 × 200 mL capacity supports formulation-batch volumes without a custom large-volume instrument.
Vaccine and protein production. Cell-pellet recovery at 5,000–6,000 × g with 200 mL bottles fits typical bench-scale fermentation and tissue-culture production runs; switching rotors covers downstream microtube cleanups at higher RCF.
Environmental and forensic separations. Sediment, microplastics, and particulate water-quality work uses 200 mL bottles with consistent swing-out geometry; phase-extraction and density work in forensics benefits from selectable accel/decel including unbraked.
Industrial process QC. Crude-oil water content, lubricant analysis, and similar industrial-QC workflows often specify 4 × 200 mL bottle format at consistent RCF. The Z327 covers this directly.
Multi-use academic core. With a microtube rotor swap, the same instrument handles routine miniprep / spin-column work; the RFID rotor ID + per-rotor speed cap means cross-user rotor-swap mistakes are caught at insertion, not mid-spin.
Design Architecture
RFID rotor identification with per-rotor over-speed protection. Each rotor in the Z327 family carries an RFID tag; on insertion the drive reads it and caps maximum speed at that rotor's rated ceiling. Operator cannot accidentally over-spin a rotor designed for lower speed.
Active imbalance identification with rotor-specific cut-off. Per-rotor imbalance thresholds, what's acceptable for a 200 mL swing-out rotor differs from a 24-tube microcentrifuge rotor. The drive applies the right threshold automatically.
Motor-driven lid lock with safety interlock. Hard interlock; the lid cannot unlock during a run.
Maintenance-free induction motor. No brush wear; institutional-duty service life.
Microprocessor with one-handed touch operation. Splash-proof keypad, gloves-friendly, large LCD with simultaneous set / actual display.
Selectable accel/decel with audible run-end alert. Multiple melody options for the end-of-run signal, useful when multiple instruments are in the same room and operators need to identify their cycle by ear.
Optimized airflow keeps the chamber near ambient during long runs in non-refrigerated configurations. (For active temperature control, see the Z327-K.)
Stainless-steel sample chamber.
Quick rotor exchange. Single-spindle wing-nut lift-off; rotor identity flows automatically via RFID after swap.
Ordering & Configuration
Ships without rotor. The Z327 body ships with operator's manual and power cord. Select your rotor from the Z327 rotor catalog (linked from this page), common configurations include the 4 × 200 mL swing-out rotor (Z327-200 family) with a deep adapter library down to 1.5 / 2.0 mL microtubes, the 6 × 50 mL fixed-angle for higher-speed conical work, plus 24 × microtube high-RCF rotors.
Voltage variants: The 230 V / 50-60 Hz model is available by special order.
Refrigerated upgrade path: Z327-K: same chassis with -20 °C to +40 °C refrigeration. Same rotor catalog, deeper chassis, higher power input.
Step-up for larger volumes: Z446 for 4 × 750 mL capacity at the same 16,000 rpm class; Z366 for 6 × 250 mL conical bottle 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 Z327? 18,000 rpm / 23,542 × g.
What is the Z327's sample capacity? 4 × 200 mL in swing-out configuration, plus 6 × 50 mL conical and 24 × microtube formats via interchangeable rotors.
Is a refrigerated version of the Z327 available? Yes. The Z327-K adds −20 °C to +40 °C refrigeration on the same chassis and shares the Z327 rotor catalog.
Does the Z327 ship with a rotor? No. It ships without a rotor; select from the Z327 rotor catalog. RFID rotor identification caps speed at each rotor's rated ceiling at insertion.
What voltage does the Z327 use? 120 V / 50–60 Hz standard; a 230 V / 50–60 Hz model is available by special order.
