Used Lab Equipment

Features:

The Type 70 Ti, rated for 70 000 rpm, is a fixed angle rotor designed to centrifuge up to eight tubes at a 23-degree angle to the axis of rotation. Used in Beckman Coulter class H, R, and S preparative ultracentrifuges, the rotor develops centrifugal forces sufficient for applications including pelleting of small particles, and purification of viruses and subcellular organelles using sucrose gradients. Up to 312 mL of sample and gradient can be centrifuged per run. The rotor is made of titanium and is finished with black polyurethane paint. The aluminum lid and handle are anodized for corrosion resistance. The handle is interchangeable with the Type 70.1 Ti rotor handle but no others. O-rings made of Buna N rubber in the lid and handle maintain atmospheric pressure inside the rotor during centrifugation, if they are properly lubricated. The lid is a patented design that seats on the rotor body so that centrifugal force aids sealing. Four small holes in the lid provide a temporary vent, preventing pressure build-up and extrusion of the large lid O-ring in the event of leakage. Because of the weight of the rotor, drive pins are not required in the rotor drive hub cavity.
