The invention relates to a method of producing a micro fluidic device as well as a microfluidic device. The method comprises producing a cartridge base comprising an upper face, a channel and a lid for said channel and fixing said lid to said upper face of said cartridge base to form a flow channel through said micro fluidic device. The cartridge base comprises a first and a second borderline edge between the upper face of the cartridge base and the channel, and the cartridge base comprises at least one, groove in said upper face extending along at least one of the first and the second borderline edges, thereby forming an outer groove edge, defined as the edge between the groove farthest away from the channel, and an outer face area of said cartridge base defined as the upper face area on the side of the outer groove edge away from the channel. The method comprises fixing said lid to said cartridge base along its outer face area, preferably so that the groove and the channel is not completely sealed from each other. In one embodiment the cartridge base comprises at least one ridge upper face area, defined as an upper face area of the cartridge base between a borderline edge and an Inner groove edge, the method comprises in this embodiment fixing said lid to said cartridge base along its outer face area, without simultaneously fixing, e.g. by sealing, said ridge upper face area to said lid, whereby a ridge-lid gap is formed between said lid and said ridge upper face area. |
