Microfluidic channel, method for its implementation, and microfluidic system containing said channel

The invention relates to a microfluidic channel (6) with shifted levels comprising a channel pillar (2a, 2b) and a channel bridge (3) which microfluidic channel (6) connects a channel (4a, 4b), situated in a first level of a base plate (1, 11) which contains a microfluidic system, with a second level of said base plate (1, 11). A longitudinal hollow with an edgeless cross-section is connected, as a channel pillar (2a, 2b), with one end, to the ending of the channel (4a, 4b) to be connected and formed in the first level of the base plate (1, 11), furthermore, the channel bridge (3) created at the second level of the base plate (1, 11) and having a cross-section fitting to the channel pillar (2a, 2b) is surrounded by a filling-up material (7) filled in subsequently, and a rounding-off is formed at the junction of the connecting end of the channel bridge (3) and the end of the channel pillar (2a, 2b) extending to the second level.
