The Z36 HK is the result of many years of experience in the design of universal centrifuges, high speed centrifuges and compact micro centrifuges. The result is a "Super-Speed" centrifuge with unmatched performance amongst benchtop centrifuges. A robust motor drive powers a variety of high speed angled rotors to speeds that would generally only be achievable in large, floor-standing ultra centrifuges. 2. 0ml micro tube samples can reach forces above 65, 000xg, while 50ml samples, as high as 41, 410xg. In addition to its high speed capabilities, the Z36 HK doubles as a universal centrifuge with a 4 x 250ml swing out rotor (offering inserts for all common tube sizes) as well as a 2 x 3 position swing-out microplate rotor. 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.
