An apparatus and method for providing an accurately regulated flow of liquid medium to a device mounted in or on a rotor of a centrifuge, comprises a scoop on the rotor having a mouth opening forwards in the direction of rotation, with a duct connecting the mouth to the device; the liquid medium being projected as a jet into the path of the rotating scoop so that the mouth chops out a mid-portion of the jet during each revolution, and feeds it to the device. Rotation rates are high, typically 50,000 rpm for devices like liquid flow density balances for mass detection, but may be less and/or variable with SFFF devices. |
