The Z207-A is the clinical-laboratory variant of Hermle's Z207 chassis — same compact form factor as the Z207-H Hematocrit Centrifuge and Z207-M Microcentrifuge, but configured around an 8 × 15 mL fixed-angle rotor that ships included with the instrument. 15 mL conical tubes are the dominant primary-blood-collection format for routine clinical separation work, and the Z207-A is engineered for that workflow specifically: 6,800 rpm / 4,394 × g spin ceiling, 8-tube parallel throughput per cycle, and EZ-Scroll touchpad control sized for shared clinical-lab use. Where the Z207-H targets capillaries (hematocrit) and the Z207-M targets microtubes (molecular biology), the Z207-A is the Z207-chassis pick for routine clinical 15 mL workflows.

Application Profile
Clinical 15 mL serum / plasma separation. Standard Vacutainer 15 mL primary tubes spin at 1,800–3,000 × g for 10 minutes to produce clean serum or plasma supernatant. The Z207-A's 4,394 × g ceiling covers this with margin; the 8-position rotor handles a typical phlebotomy batch in one cycle.
Clinical-research cell-pellet recovery. Cell-suspension cultures collected into 15 mL conical tubes pellet cleanly at 300–500 × g (mammalian) or 1,500–3,000 × g (bacterial) — both well within the Z207-A's range.
Microbiology routine prep. 15 mL bacterial culture aliquots for sub-culturing, identification, or downstream extraction prep.
Educational and teaching clinical-lab work. EZ-Scroll touchpad and gloves-friendly programming support rotating students and lab tech trainees; the splash-proof keypad tolerates the wet-bench reality of clinical sample handling.
Point-of-care satellite labs and small clinical practices. The 11 × 13.7 inch footprint and 17.6 lb weight fit a standard clinical bench; 50 W power input is low enough for shared-circuit installations without dedicated electrical service planning.
Design Architecture
Maintenance-free induction motor. No brush wear; the air-cooling system keeps sample temperature near ambient through standard 5-to-10-minute clinical spin cycles.
EZ-Scroll touchpad control. Capacitive-touch programming of speed, time, and accel/decel rates. Splash-proof; gloves-friendly — important for clinical labs where operators wear gloves continuously.
Electrical lid-lock with rotor pre-selection. The lid cannot unlock during a run. Rotor type pre-selection caps maximum speed at the rotor's rated maximum — operators cannot accidentally over-spin the included 8 × 15 mL rotor or any alternative rotor swap.
Active imbalance identification with cut-off. Asymmetric loading or mid-spin tube failure triggers automatic shutdown before excursion damage. Important in clinical workflows where loading by lab tech may not always be perfectly symmetric.
Quick acceleration / deceleration within 13 seconds. Short cycle-to-cycle turnaround when running back-to-back batches.
10 acceleration and deceleration rates including unbraked deceleration. The unbraked option preserves loose pellets and density-gradient boundaries for the occasional research-style protocol that runs on the same instrument.
Sleep mode. After configurable idle time, non-essential subsystems power down to save energy and extend service life — useful in 24-hour clinical settings where the centrifuge is powered but unused most of the time.
99-slot program memory. Standard clinical protocols (serum separation, plasma prep, cell pellet) recallable by name; programs persist across power cycles.
Frequently Asked Questions
What rotor comes with the Z207-A? An 8 × 15 mL fixed-angle rotor, pre-installed — one of the few Hermle Z-series SKUs that ships rotor-included rather than rotor-separately.
What are the maximum speed and RCF? 6,800 rpm and 4,394 × g (the included rotor is rated to 4,445 × g), covering routine clinical 15 mL serum/plasma separation with margin.
How does the Z207-A differ from the Z207-H and Z207-M? All three share the Z207 chassis. The Z207-A targets 15 mL clinical workflows; the Z207-H is a hematocrit centrifuge with a 24-capillary rotor (13,000 rpm); and the Z207-M is a microcentrifuge with a 24 × 1.5/2.0 mL rotor (13,500 rpm).
What is the warranty? A 5-year Hermle warranty — 3 years full plus 2 years drivetrain.
Can the Z207-A run on 230 V? Yes, a 230 V / 50–60 Hz model is available by special order.
Ordering & Configuration
Included: Z207-A body with the 8 × 15 mL fixed-angle rotor pre-installed (Z207-A is one of the few Hermle Z-series SKUs that ships rotor-included rather than rotor-separately), operator's manual, power cord.
Voltage variants: 230 V / 50–60 Hz model is available by special order.
Combination-rotor sibling: Z207-A-CMB ships with a different rotor configuration (combination rotor for mixed tube formats) on the same Z207 chassis.
Related within the Hermle Z207 family (same chassis, different rotor + application focus):
- Z207-H — Hematocrit Centrifuge with integrated 24-capillary rotor; clinical hematocrit workflow at 13,000 rpm
- Z207-M — Compact Microcentrifuge with 24 × 1.5/2.0 mL microtube rotor; molecular-biology workflow at 13,500 rpm
Step-up: For larger 200 mL bottle work at higher RCF, see Z327 Universal Centrifuge or Z366 for 6 × 250 mL.
Warranty & service: 5-Year Hermle warranty (3 years full + 2 years drivetrain). Rotor validation, balance checks, and North American service available through the Benchmark / Hermle distributor network.
Capital purchase processed via consultative quote. Confirm voltage, included rotor configuration, and any optional alternative rotors (the Z207-A chassis accepts other rotor formats per the Z207 rotor catalog).
