Abstract

An integrated microfluidic element (1) composed of two juxtaposed plates (3, 5) bonded together, wherein at least one plate (3) has an etched structure or pattern of channels (7) on the surface facing the other plate (1) to form sealed micro channels (7), said element having micro spacers or posts (11) distributed over the etched surface of said one plate outside of said etched structure or pattern, and walls (9) surrounding said channels (7), said walls (9) having a height equal to that of said spacers or posts (11); and a method for the manufacture of such integrated microfluidic element.
