The Z207-M is a high-speed microcentrifuge built for the 1.5 / 2.0 mL tube volumes that dominate molecular-biology bench work. In a chassis roughly the size of a shoebox, it reaches 13,500 rpm / 17,317 × g — fast enough for protein precipitations, DNA / RNA pelleting, plasmid miniprep clean-ups, and virtually every column-based nucleic-acid purification protocol that calls for microcentrifuge-class g-force. Hermle engineering, Benchmark distribution, and a 24-position rotor that keeps the footprint compact without sacrificing throughput.

Application Profile
Nucleic-acid miniprep and column purification. The 13,500 rpm ceiling covers every common spin-column protocol (Qiagen, Zymo, NEB, Promega) that specifies "maximum speed" for elution or wash steps.
Protein precipitation and pellet recovery. 17,317 × g is sufficient for TCA, acetone, and ammonium-sulfate precipitations of soluble-protein fractions, as well as post-lysis debris pelleting at the 13,000-16,000 × g range.
Short-spin workflows. The dedicated quick-key short-spin, paired with full accel/decel in 13 seconds, makes the Z207-M practical for repetitive pulse-spins during buffer changes, wash steps, or bubble removal from PCR plates.
Multi-user research groups. The 99-slot program memory tied to rotor-type recall means lab members can store their preferred protocols — and the rotor pre-selection prevents someone from accidentally exceeding the safe speed after switching rotors.
Teaching and protocol development. 10 accel/decel rates including unbraked deceleration support method-development work where separation gradients or loose pellets would be disturbed by standard deceleration.
Design Architecture
Maintenance-free induction motor. No brushes, no scheduled wear parts beyond the rotor itself. The Z207-M is designed for heavy daily use in a shared lab environment where motor-service windows would be expensive.
Microprocessor control with EZ-Scroll pad. Splash-proof foil keyboard, large LCD displaying set-point and actual values simultaneously. Programs and rotor settings persist across power cycles.
Electrical lid-lock with rotor pre-selection. The lid cannot open while the rotor spins, and the microprocessor caps speed at the pre-selected rotor's rated ceiling regardless of user input.
Active imbalance identification and cut-off. Asymmetric loading or mid-spin tube failure powers down the drive before the rotor can excurse off-axis.
Air-cooling system. Sample chamber runs near ambient; for applications where sample heating matters (long protein precipitations, thermosensitive nucleic acids), pair with a cold-room install or step down to short-burst runs.
Programmable momentary-spin (press-and-hold). Operator holds the short-spin button to run only while engaged — ideal for brief knock-down spins that don't need a full timed cycle.
Ordering & Configuration
Ships without rotor. The Z207-M body ships with operator's manual and power cord. Select your rotor from the Z207-M rotor catalog (linked from this page); the 24 × 1.5/2.0 mL rotor is the standard configuration. Bundle SKUs that include the rotor are also offered — see the bundle product pages.
Voltage variants: 230 V / 50-60 Hz model is available by special order.
Related within the Hermle benchtop line: For clinical hematocrit work, see the Z207-H Hematocrit Centrifuge — same chassis form factor, different rotor and application profile. For general benchtop spins covering 15 / 50 mL tubes at lower g-force, see the Z206-A Compact Centrifuge.
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.
