    Abstract: A method of performing a measurement of an analyte in a sample using an automatic analyzer is provided. The automatic analyzer comprises: a cartridge for dispensing a fluid, a measurement unit for performing the measurement, a sample holder for receiving the sample, and a pump for pumping the fluid out of the cartridge and into the sample holder. The cartridge comprises: a rigid portion, a flexible bladder, and an outlet. The rigid portion comprises an opening, which is connected to an inner cavity. The flexible bladder seals the opening to form a fluid chamber from the inner cavity. The fluid chamber is at least partially filled with the fluid. The pump is connected to the outlet. The method comprises: placing the sample into the sample holder, controlling the pumping of the fluid from the cartridge into the sample holder, and performing the measurement of the analyte using the measurement unit.

    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.

    Abstract: A cartridge for dispensing a fluid is provided, the cartridge comprising: a reservoir chamber configured for receiving the fluid, the reservoir chamber having a fluid outlet and a cover with a first bearing; and a stirring assembly comprising a stirrer located inside the reservoir chamber, the stirring assembly comprising a shaft connected to the stirrer. The stirring assembly can be moved between first and second positions, wherein in the first position the stirring assembly can seal the fluid outlet, the stirring assembly in the first position being configured to form a second bearing with the reservoir chamber or the fluid outlet such that the stirrer can be rotated about an axis defined by the first and second bearing, and wherein if the stirring assembly is in the second position the fluid can pass through the fluid outlet, the shaft being configured to transmit rotational power to the stirrer.

    Abstract: A cartridge for dispensing a fluid is presented. The cartridge comprises a reservoir chamber for receiving the fluid. The reservoir chamber has a fluid outlet. The cartridge further comprises a controllable dispenser component for dispensing a dispensing volume of the fluid from the reservoir chamber. The dispenser component is connected to the fluid outlet of the reservoir. The cartridge further comprises a single compressible fluid pump with a single elastic pumping element and a conduit extending from the fluid pump towards the fluid outlet. The fluid pump discharges a mixing volume of the fluid from the conduit into the reservoir chamber upon compression of the elastic pumping element. The mixing volume depends on the degree of compression of the elastic pumping element. The fluid pump sucks in the mixing volume from the reservoir into the conduit upon decompression of the elastic pumping element.
