Claim:
An arrangement comprising: a body having a three-dimensional structure; and a base plate joined to the body, wherein the body comprises a reservoir, a limiting wall and at least one flow-through cell part having an inlet and an outlet, wherein the limiting wall separates the reservoir from the inlet and forms a channel above the inlet and the limiting wall has a height lower than the height of the body, the outlet is located in the reservoir, wherein an interior space is formed between the body and the base plate, the interior space having an inlet opening and an outlet opening, and fluidically connecting the inlet and the outlet, wherein the at least one flow-through part and the interior space form a flow-through cell, and wherein the inlet is arranged on the three-dimensional structure of the body closer to the base plate than an opening of the channel away from the inlet and the inlet has a funnel-shaped border and is adapted to discharge to the inlet opening towards the base plate, the funnel-shaped border having a shape allowing a tip of a pipette to be maneuvered close to the base plate to fill the flow-through cell.
