The Tomy MicroONE Mini Centrifuge is the ideal personal centrifuge.   They are perfect for dozens of low g-force tasks and small enough to keep handy whether you need it at the work bench, in the cold room, or in a fume hood.   The MicroONE features snap-on rotors that spin either eight 1.5 to 2.2ml microtubes or two 8-well tube-strips (200 micro liters size), and they are so economical, you can afford one for each person in the lab.
