Abstract

The comprises at least one sample receiving chamber for a sample liquid, and a distributor channel for sample liquid connected to said at least one sample receiving chamber, with at least one such distributor channel extending from each sample receiving chamber. The sample support further comprises at least one reaction chamber entered by an inflow channel branched off said at least one distributor channel, and a venting opening for each reaction chamber. Each distributor channel and each inflow channel are dimensioned to have the liquid transport through the distributor and inflow channels effected by capillary forces. In each reaction chamber, the entrance region of the inflow channel is provided with a means for generating a capillary force causing the sample liquid to flow from the inflow channel into the reaction chamber.
