<p>A multilayer microfluidic module (10) contains a micromixer (12) comprising, in order along an internal fluid path (14), a first fluid channel (16) lying within a first layer (51) of the module (10) along a first direction (15) with the first layer having a lower boundary (21); at least one additional fluid channel (17) lying within the first layer (51) of the module (10) along an additional direction (19); a first injection passage (20) extending from a first injection passage inlet (22) in the lower boundary (21) of the first layer (51) of the module (10) through a second layer (52) of the module (10) to a first injection passage outlet (24), the first injection passage inlet (22) being fluidically connected to the first fluid channel (16) and to the additional fluid channel (17) either individually through the lower boundary (21) of the first layer (51) or via a manifold (25) within the first layer (51); and a second fluid channel (26) lying within a third layer (53) of the module (10), the third layer (53) having an upper boundary (30), the second fluid channel having a width W26; wherein the first direction (15) and the additional direction (19) are non-collinear, and wherein the first injection passage outlet (24) is centered within the second fluid channel (26) in the direction of the width W26, and has a length L24 along the second fluid channel (26) and a width W24 in the direction of the width W26, and wherein the width W24 is narrower than the width W26, and wherein the first injection passage outlet (24) has a length-to-width ratio L24/W24 of greater than 1:1.</p> |
