Some in-vitro diagnostic analyzers, e.g. in the point of care field, like blood gas and metabolite analyzers use pouches of different sizes each containing a respective volume of a fluid (FIG. 1), such as e.g. calibration fluids, quality control fluids, washing fluids and the like. The pouches can be packed together into a fluidic pack and connected to a valve system. The fluidic pack is then inserted into the analyzer and fluids can be aspirated from the pouches into a fluidic system of the analyzer by a pump via the valve system.When several pouches have to be connected next to each other, the difference in sizes prevents obtaining a compact arrangement of the fluidic pack. Also, during transportation of the fluidic pack moving pouches fixed only by their connector to the valve system, can cause rupture and leakage.
