The invention relates to a valve structure for a microfluidic channel, where the valve serves the opening and closing of a channel (8) on a second level raised through channel pillars from the plane of the microfluidic channel network at the first level of a base plate (1), and where the channel wall is formed of a resilient material. The valve structure consists of a base plate (1) part, of protruding supporting walls (3, 3′) belonging to the base plate (1) and of a resilient part (7) between the supporting walls (3, 3′), within which the channel (8) is formed, and it consists furthermore of pressing appliances (9, 9′) situated on the two sides of the channel, as well as of displacement appliance (10) ensuring the movement of the pressing appliances in the direction of the mid-line of the channel (8). |
