A cuvette and a method of use prevent nucleic acid amplified by PCR technology from being released to the atmosphere, while still proceeding to a detection step to determine whether or not the nucleic acid is present. Detection reagents are either pre-incorporated into compartments in the cuvette or added after amplification. In the latter case, a check valve prevents amplified nucleic acid from being released. Transfer of liquids between compartments is achieved via the use of flexible compartment walls and an external pressure source, or via pistons that are part of the cuvette and operate on the compartments as a piston within a piston chamber.

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.
