Description
JA-25.50 Rotor, Fixed Angle, Aluminum, Single Lock Lid, 8 x 50 mL, 25,000 rpm, 75,600 x g. Typical applications include pelleting bacteria, processing tissue homogenates, subcellular particulates, and other routine pelleting such as precipitates and phase separations. For use in Avanti® J Series and the classic but ultra reliable J2 series centrifuges. The JA-25.50 fixed-angle rotor is designed to hold up to eight 50-mL tubes at a 34-degree angle). Used in Beckman Coulter Avanti J and J2 series centrifuges, the JA-25.50 rotor develops centrifugal forces that can efficiently pellet cells from large volumes, or cell particles from tissue homogenates. Short column methods (i.e., partially filled tubes) may also be used to purify large quantities of virus in a cushion gradient. The JA-25.50 rotor has a patented fluid-containment annulus, located below the O-ring sealing surface (see Figure 2). If tubes are overfilled or if leakage occurs during centrifugation, the annulus holds enough volume that all of the liquid is kept inside the rotor—even if all eight tubes leak at the same time. This feature virtually eliminates the escape of liquid into the centrifuge chamber.
