MyFuge12 Mini Centrifuge. COMBI-Rotor for tubes and strips. Twice the capacity of traditional mini centrifuges. Near silent operation. Starts and stops with opening/closing of lid. Unlike traditional mini centrifuges, the 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 4 PCR strips simultaneously. With a fixed speed that produces 2,000 xg, this centrifuge is perfect for quick spin downs. Simply close lid and unit quickly ramps up to 5500 rpm. Open lid, and rotor quickly decelerates for removal of samples. At just 5.5" wide and less than 4.5" tall, MyFuge 12 truly is a personal centrifuge with unmatched capacity and flexibiilty.
