Abstract: A microfluidic valve includes a carrier layer and a flexible membrane layer arranged on a surface of the carrier layer. The surface of the carrier layer has a valve chamber in the form of a spherical cap and a membrane formed by the flexible membrane layer covers at least the valve chamber. A plurality of microfluidic channels opening into the valve chamber are formed in the surface of the carrier layer. Moreover, an inflow channel and an outflow channel are connected to one another by a microfluidic connection channel. The connection channel and the valve chamber are positioned relative to each other in such a way that in the closed state of the membrane, a fluid can flow from the inflow channel via the connection channel into the outflow channel to bridge the valve chamber, while the at least one supply channel is closed by the membrane.
