The Hermle Z32 Refrigerated Centrifuges utilizes much of the technology as the Z326 series, with a larger and more powerful motor drive, providing increased speed up to 20,000 rpm (38,007 xg). With a variety of rotor options available, the Z32 HK is not only ideal for high-speed separations, but it would also be classified as a “universal” centrifuge, offering economy angled and swinging bucket rotors for lower speed applications. Tubes from 0.2mL up to 85mL can be accepted, and rotors be exchanged without any requiring programing, utilizing the instant rotor identification system.

Despite an impressive capacity of up to 4 x 145mL (or 6 x 85mL), the Z32-HK is surprisingly compact. The refrigeration system is conveniently located behind the rotor chamber, resulting in a narrow design of less than 16-inches wide. 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 acceleration/deceleration rates and change the end of run alarm tone.
