Based on many years of centrifuge design and state-of-the-art technology, the Z36HK centrifuge offers super speeds as high as 30,000 rpm (65,390 x g) along with 9 rotor options. Featuring a modern design with an easy to read LCD display and easy to use control panel, this is the most capable centrifuge of its kind. It's small and compact, yet can perform as well as a full size floor model in a convenient table-top size. 6 x 250ml and 6 x 50ml high-speed angle rotors are included with the 9 rotor options, and there is a knob you can use to quickly and easily adjust all of the operating parameters, including run time up to 99 hours, speed (rcf or rpm), temperature (-20°C - 40°C), and many others. As soon as you close the centrifuge lid, the new rotor recognition system recognizes the rotor and the rotor number is displayed.
