A removable pipette tip (10) and pipette therefor (50), which provide separation of substances of a liquid within the tip by centrifuging the tip. The tip comprises a liquid-confining cavity (16) disposed about an axis of symmetry (14), a dispensing aperture (18), and separating means (26, 300) spaced along the axis away from the dispensing aperture, for separating one of the liquid substances when the tip is spun around such axis. The pipette is provided with means (86, 88) permitting continuous rotation of the tip. Means (90, 250) are provided for spinning the pipette tip at high speed. |
