The Z216-MK is a compact, quiet, and powerful refrigerated microcentrifuge with a remarkably small footprint, but still offers a uniquely designed 44 x 1.5ml dual row rotor, nearly doubling the capacity when compared to traditional microcentrifuges. All common microtubes (0.2ml, 0.5ml, 1.5ml, 2.0ml) can be accepted as well as PCR strips, hematocrit tubes, and even 5.0ml centrifuge tubes, while its advanced microprocessor controls allow for setting/displaying of the rotational speed in either rpm or rcf.
