Z307 Universal Centrifuge, 120V

The Z307 is a 4-place swing-out universal centrifuge sized for the 200 mL-bottle workflows that show up routinely in cell-culture cores, blood-banking labs, and academic research groups: 200 mL conical or round-bottom bottles, 50 mL conical secondary tubes via adapters, and the full 1.8–10 mL clinical-tube range. At 4,500 rpm / 3,350 × g, it covers the lower-g separation work where you don't need a 14,000 rpm microcentrifuge but you do need swing-out geometry for clean phase boundaries.

Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Key Specifications

Application Profile

Cell-culture pelleting at scale. 4 × 200 mL bottles let a primary-tissue or hybridoma group pellet a full preparation in one spin rather than across multiple smaller-bottle cycles. 3,000–3,350 × g is squarely in the cell-pelleting range for mammalian, insect, and most microbial cultures.

Clinical primary-tube separation. 50 mL and 15 mL adapters fit standard primary blood collection tube formats; the swing-out geometry produces the horizontal boundary needed for clean serum / plasma / buffy-coat reads.

Density-gradient and step-gradient work. Swing-out geometry preserves continuous density gradients during deceleration; the Z307's selectable accel/decel rates (including unbraked) suit gradient-preservation protocols.

Phlebotomy and small-clinical-lab work. Adapter sets cover the 5–10 mL Vacutainer range for routine clinical separation.

Method-development and teaching. 99-slot program memory plus quick-key short-spin support repetitive pulse-spin protocols and standardized program recall across rotating users.

Design Architecture

Maintenance-free induction motor. No brush wear; suited for daily shared-use deployment.

Active imbalance identification with cut-off. Asymmetric loading or mid-spin tube failure triggers automatic shutdown before excursion damage.

Motor-driven lid lock. Hard interlock — lid cannot open while the rotor is in motion, and the drive will not engage unless the lid latches.

Microprocessor control with one-handed touch operation. Large LCD shows set-point and actual values simultaneously; splash-proof foil keypad tolerates wet-bench use.

Selectable acceleration / deceleration with unbraked option for gradient and loose-pellet preservation.

Stainless-steel sample chamber for spill containment and chemical resistance.

Ordering & Configuration

Ships without rotor. The Z307 body ships with operator's manual and power cord. Select your rotor and adapter set from the Z307 rotor catalog (linked from this page) — common configurations include the 4 × 200 mL swing-out rotor with adapters down to 1.5 / 2.0 mL micro tubes, plus a 6 × 50 mL fixed-angle option for higher-speed work.

Voltage variants: The 230 V / 50-60 Hz model is available by special order.

Step-up: For higher-speed work in the same volume range, see the Z327 Universal Centrifuge (18,000 rpm / 23,542 × g) which shares the 4 × 200 mL swing-out rotor catalog.

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.

Frequently Asked Questions

What is the maximum speed and RCF of the Z307? 4,500 rpm / 3,350 × g.

What is the Z307's capacity? 4 × 200 mL in swing-out configuration, with adapters covering 50 mL, 15 mL, and clinical 5–10 mL tube formats.

Is the Z307 a high-speed centrifuge? No — it is a lower-g swing-out universal for cell pelleting and clinical separation. For higher speed in the same volume range, see the Z327 (18,000 rpm / 23,542 × g).

Does the Z307 ship with a rotor? No — select the rotor and adapter set from the Z307 rotor catalog.

What voltage does the Z307 use? 120 V / 50–60 Hz standard; a 230 V / 50–60 Hz model is available by special order.
