Sample support

A sample support comprising

• at least one sample receiving chamber for a sample liquid,
• a distributor channel for sample liquid, connected to said at least one sample receiving chamber, with at least one such distributor channel extending from said at least one sample receiving chamber,
• a plurality of reaction chambers each comprising a cavity which is delimited by surfaces and is entered by an inflow channel branched off said at least one distributor channel, and
• a venting opening for each reaction chamber, wherein each venting opening of each reaction chamber has a connecting channel extending therefrom and wherein a plurality of such connecting channels are arranged to enter respectively one venting collecting channel comprising a venting collecting opening,
• wherein each distributor channel and each inflow channel is dimensioned to have the liquid transport through the distributor and inflow channels effected by capillary forces, and wherein, in each reaction chamber, said surfaces in the entrance region of the inflow channel which are provided for delimiting said cavity are configured as a means for generating a capillary force causing the sample liquid to flow from the inflow channel into the reaction chamber exclusively by capillary force.
