Beckman Type JS-13 Four Place Swing Bucket Centrifuge Rotor 13000 RPM Max.
This is a used item. We are not sure of the specific model of centrifuge this is for. The top lid measures about 12 3/8" overall diameter. The arbor is about 1 5/16" diameter. The top knob that is shown in the pictures does not serve to hold the lid on and must screw into the actual centrifuge. The o-ring looks to be in good condition. This unit weighs about 29 pounds. We are not able to test it. It only comes with what is shown in the pictures.
