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 dispenser for dispensing a fluid is presented. The dispenser comprises a compressible elastomeric fluid conduit having a first end and a second end for flowing the fluid from the first end to the second end, a first check valve and a second check valve distanced in the conduit for forming a fluid chamber, and an actor for compressing the fluid chamber for dispensing a portion of the fluid. At least the second check valve is a duckbill valve. The second check valve is located at the second end of the conduit. The second check valve has sealing lips that extend beyond the second end of the conduit.

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.
