Abstract:
An automatic analyzer cartridge, spinnable about a rotational axis, has fluid and aliquoting chambers, a metering chamber connected to a vent that is nearer to the rotational axis than the metering chamber, first and second ducts connecting the fluid and aliquoting chambers, and the metering and aliquoting chambers, respectively. Metering chamber side walls taper away from a central region, wherein capillary action next to the walls is greater than in the central region. Fluid flows to the metering chamber using capillary action via the second duct that has an entrance and exit in the aliquoting and metering chambers, respectively; the exit being closer to the rotational axis than the entrance. A downstream fluidic element connects to the metering chamber via a valve. A fluidic structure receives and processes a biological sample into the processed biological sample and has a measurement structure that enables measurement of the processed biological sample.

Claim (Index 1):
A method of aliquoting a fluid using a cartridge, wherein the cartridge is operable for being spun around a rotational axis, wherein the cartridge comprises:\n a fluid chamber for receiving a fluid; an aliquoting chamber; a first duct connecting the fluid chamber and the aliquoting chamber; a metering chamber, wherein the metering chamber is operable for causing fluid to fill the metering chamber using capillary action, wherein the metering chamber has side wall regions and a central region, wherein the side wall regions are narrower than the central region in a cross sectional view of the metering chamber, wherein capillary action next to the side wall regions of the metering chamber is greater than in the central region of the metering chamber; a second duct connecting the metering chamber with the aliquoting chamber, wherein the second duct comprises a duct entrance in the aliquoting chamber, wherein the second duct further comprises a duct exit in the metering chamber, wherein the duct exit is closer to the rotational axis than the duct entrance, wherein the second duct is operable for causing fluid to flow to the metering chamber using capillary action; and a vent connected to the metering chamber, wherein the vent is nearer to the rotational axis than the metering chamber, wherein the method comprises the steps of: filling the fluid chamber with the fluid; controlling the rotational rate of the cartridge to transport the fluid from the fluid chamber to the aliquoting chamber via the first duct; decreasing the rotational rate of the cartridge to permit the fluid in the aliquoting chamber to flow into the second duct and to fill the metering chamber a first time; increasing the rotational rate of the cartridge to transfer a first part of the fluid from the metering chamber and to transfer a first remaining part back into the aliquoting chamber; decreasing the rotational rate of the cartridge to permit the fluid in the reservoir to flow into the second duct and to fill the metering chamber a second time; and increasing the rotational rate of the cartridge to transfer a second part of the fluid from the metering chamber and to transfer a second remaining part back into the aliquoting chamber.
