ABSTRACT:
There are described a novel removable pipette tip and pipette therefor, which provide separation of substances of a liquid within the tip by centrifuging the tip. The tip comprises a liquid-confining cavity disposed about an axis of symmetry, a dispensing aperture, and separating structure spaced along the axis away from the dispensing aperture, for separating one of the liquid substances when the tip is spun about such axis. The pipette is rotatable and either the pipette or the analyzer includes a driver for spinning the pipette tip at high speed.
