Refrigerated Centrifuge is a high speed centrifuge for medium capacity needs. It allows for molecular applications in tubes up to 250 mL and offers additional swing–bucket and fixed–angle rotors as well as deep well plate capacity for increased versatility. Refrigerated Centrifuge is equipped with swing-bucket rotor A-4-44, 15/50 ml adapters and fixed-angle rotor F45-30-11 30 x 1.5/2 ml. A low temperature centrifuge is used to determine sedimentation velocity, shape and mass of macromolecules, separation of phases, isolate viruses, organelles, membranes and biomolecules such as DNA, RNA and lipoproteins. This can also be used for phase separation of nanomaterials.
