Benchmark Hermle Z446 and Refrigerated Z446-K High Capacity Centrifuges


The Z446 universal centrifuge series offers the highest capacity of any benchtop Hermle-Benchmark model. With air-craft grade, premium alloy construction, the 4 x 750mL swing out rotor can withstand centrifugal forces upwards of 4,000 x g with full loads of up to 48 x 50mL or 68 x 15mL tubes.

Advanced microprocessor controls allow for instant rotor identification, which automatically converts the rotational speed to the relevant g-force (rcf), preventing the user from setting a speed above the capabilities of the installed rotor. In addition to retrieving saved programs, the easy to use front panel can adjust accel/ decel rates, and change the end of run alarm tone.

Rotor exchange is simple and requires less than one minute. An included rotor wrench can be used to loosen and install all rotors. As soon as the rotor is
placed on the motor shaft, the identification process activates and the installed rotor code is displayed on the backlit LCD display.Z446 Centrifuge Picture

Hermle Microplate Carrier Dish for Chamber Slides and Dishes - Pipette_ComNew Product! - Benchmark Hermle Chamber Slide or 35/60mm Dish Carrier for Microplate Rotor or Carrier (Cat # Z326-02MP)

Z326-MPCA is a combination carrier that can fit 3 Chamber Slides, a 35mm Dish, or a 60mm Dish. It is the ONLY accessory available on the market for centrifugation of chamber slides or 35/60mm dishes. Before this carrier, researchers had to improvise a carrier, which could yield unsafe or improperly completed centrifugation.

The carrier is ideal for:

  • Inducing Cell < -- > Bacteria or Viral Particles contact
  • Inducing cultured cells and particles contact (nanoparticles, beads, non-soluble reagents)
  • Treatment or washing of cultivated cells in suspension
