The invention relates to a dispensing unit for dispensing fluid into an external container. The dispensing unit comprises: a connector, a reagent cylinder for storing the fluid, and a locking ring. The connector comprises an upper fastener, and a bottom wall with at least one passage therethrough. The reagent cylinder comprises at least one compartment for storing the fluid, which compartment comprises at least one opening through a cylinder bottom. The at least one opening is located so that for at least one mutual orientation of the reagent cylinder and the connector, fluid can flow from the compartment to the external container via the at least one opening and the at least one passage. The locking ring comprises a second fastener which fastens to the upper fastener of the connector, so that when the locking ring is tightened, the reagent cylinder is pressed towards the interior bottom of the connector. |

1. A dispensing unit for dispensing fluid into an external container, comprising:
a connector comprising:
an upper fastener, anda bottom wall having an interior bottom surface, an exterior bottom surface, and at least one passage (9) between the interior bottom surface and the exterior bottom surface, a reagent cylinder for storing the fluid, the reagent cylinder being adapted to be rotatably fitted into the connector, and comprising:
a cylinder bottom, andat least one compartment for storing the fluid, the compartment comprising at least one opening through the cylinder bottom, wherein the at least one opening is located so that for at least one mutual orientation of the reagent cylinder and the connector, the at least one opening is aligned with the at least one passage, and fluid can flow from the compartment to the external container via the at least one opening and the at least one passage, a locking ring comprising:
a second fastener, which attaches to the upper fastener of the connector, so that when the locking ring is tightened, the cylinder bottom of the reagent cylinder is pressed towards the interior bottom surface of the connector and creating a fluid tight sealing between the connector and the reagent cylinder. |
