An electronic device comprising a substrate; a pair of stacks of polar semiconductor materials which create a charge by spontaneous andor piezoelectric polarization; one of the pair of stacks having a spontaneous andor piezoelectric polarity which is in a direction opposite to the other of the pair of stacks; whereby due to the opposing polarities, the polarization is balanced. The smaller of the MEMS die and the ASIC die is stacked on the larger of the MEMS die and the ASIC die. A dilution vessel for preparing the sample solution by diluting a sample fluid with a diluting fluid. In order to avoid disadvantageous piling up of the sliver on the intermediate storage device andor in the sliver can and to allow can changing at maximum sliver production speeds, the immediate storage device is arranged to be driven such that it is movable whilst collecting the sliver.
