A microfluidic device comprising in sequence first, second and third layers of plastics materials. A microfluidic circuit including a laterally extending microfluidic channel is formed at the interface between the first and second layers by surface structure in one or both of the first and second layers. A via is formed in the third layer for supplying or removing fluid to or from the microfluidic circuit. A conduit is formed in the second layer to provide fluid communication between the microfluidic channel and the via. A weld is formed at the interface between the second and third layers in a continuous closed path around the via and forms a fluid-tight seal for fluid flow between the via and the microfluidic circuit. |
