    Abstract: A cartridge for dispensing a fluid is presented. The cartridge comprises a reservoir chamber for receiving the fluid and for receiving a ventilation gas. The reservoir chamber comprises an inlet for receiving the ventilation gas and an outlet for dispensing the fluid. At least a portion of the reservoir chamber is filled with the ventilation gas when in an operating position. The inlet is located in the portion being filled with the ventilation gas. The fluid comprises a reagent. The cartridge further comprises a baffle for restricting gas diffusion through the inlet. The reservoir chamber receives the ventilation gas via the baffle. The inlet is maintains a constant gas pressure within the portion of the reservoir chamber that is being filled with the ventilation gas.

    Abstract: A valve for dispensing a fluid comprising a dry portion and a wet portion is presented. Only the wet portion is contacted by the fluid. The wet portion comprises a fluid dispenser unit having a inlet opening, a capillary nozzle providing a fluid outlet, a cavity, the capillary nozzle having an end within the cavity, and a plunger. The plunger moves within the cavity into an opening position allowing an inflow of the fluid through the inlet opening through the cavity and an outflow of the fluid through the capillary nozzle. The plunger has a sealing surface directed towards the end of the capillary nozzle. The plunger moves into a closing position for sealing the end of the capillary nozzle with the sealing surface. The dry portion comprises a closing component for exercising a magnetic closing force onto the plunger for attracting the plunger into the closing position.

    Abstract: An automatic analyzer cartridge, spinnable around a rotational axis, has aliquoting and metering chambers, a connecting duct there between, and a vent connected to the metering chamber and nearer to the rotational axis than the metering chamber. The metering chamber has side walls that taper away from a central region. Capillary action next to the side walls is greater than in the central region. A circular arc about the rotational axis passes through a duct entrance in the aliquoting chamber and a duct exit in the metering chamber. The cartridge has a downstream fluidic element which is part of a fluidic structure for processing a biological sample into the processed biological sample. A valve connects the metering chamber to the fluidic element, which is fluidically connected to the fluidic structure. The fluidic structure receives the biological sample and has a measurement structure for enabling measurement of the processed biological sample.
