--------------------------------------------
*Relative Centrifugal Field (RCF) is the ratio of the centrifugal acceleration at a specified radius and speed ( rw 2 ) to the standard acceleration of gravity (g) according to the following formula:
wherer is the radius in millimeters, w is the angular velocity in radians per second (2πRPM/60), and g is the standard acceleration of gravity (9807 mm/s 2 ). After Substitution:
DESCRIPTION
The Wi 90 vertical tube rotor, rated for 90 000 rpm, is designed to centrifuge up to eight 1/2-in. diameter Quick-Seal® tubes in an upright position. Used in class H, R, and S preparative ultracentrifuges, the rotor develops centrifugal forces that can efficiently band DNA or isolate proteins an density gradients. Up to 40.8 mL of gradient and sample can be centrifuged per run.
The rotor is made of titanium and is finished with black polyurethane paint. A rotor plug, tube spacer and, if necessary, a floating spacer, hold each tube in the rotor. A Hytrel gasket forms a closure around each rotor plug. Rotor plugs are red-anodized and spacers are blackanodized aluminum; floating spacers are Noryl plastic. Because of the weight of the rotor, there are no drive pins in the rotor drive hole.
