JA-14Rotor

The JA-14 fixed angle rotor, rated for 14 000 rpm, is designed to centrifuge up to six 250-mL containers at a 25-degree angle to the axis of rotation. Used in Beckman Coulter J2, J6, and Avanti J series centrifuges, the rotor develops centrifugal forces that can efficiently pellet bacterial cells from large volumes, or particles from tissue homogenates. Short column methods (such as partially filled tubes) may also be used to purify a large quantity of virus in a step gradient. Up to 1.5 liters of sample and gradient can be centrifuged per run. The rotor body and lid are made of aluminum and are anodized for corrosion resistance—the rotor is black and the lid is blue. The lid knob secures the rotor to the drive hub.
