Unlike traditional mini centrifuges, the new MyFuge? 12 eliminates the need to change rotors when switching between microtubes and PCR strips. The included, unique COMBI-Rotor? is all that is required for running 12 microtubes and/or 4 PCR strips. With a fixed speed that produces 2,000 xg, this centrifuge is perfect for quick spin downs. Simply close the lid and the unit quickly ramps up to 5500 rpm. Open the lid, and the rotor quickly decelerates for removal of samples. At just 5.5 inches wide and less than 4.5 inches tall, the MyFuge 12 truly is a personal microcentrifuge with unmatched capacity and flexibilty.
