摘要： A microfluidic flow controller comprising a substrate having formations defining two or more fluid channels having channel fluid ports which are open at an outer surface of the substrate; and a flexible layer having formations defining a fluid channel which, when the flexible layer is positioned over the substrate so as to cover at least the channel fluid ports, provides a fluid communication path between the channel fluid ports but which, when a force is applied to press the flexible layer towards the substrate, deforms so as to inhibit fluid communication between the channel fluid ports.

摘要： A microfluidic mixer, formed by two parts, a first part being a substrate having formations defining fluid channels on an outer surface that is directed towards a second part, which is a flexible layer. The flexile layer has formations defining a fluid channel which, when the flexible layer is positioned over the substrate so as to cover the fluid channels of the substrate provides a fluid communication path. A section of said communication path comprises at least first and second fluid channels for providing first and second fluids. The first and second fluid channels merge before an inlet of a mixing chamber. The mixing chamber comprises perturbation formations. An outlet of the mixing chamber is connected to an outlet fluid channel. The flexible layer comprises points for compression at the inlet and outlet of the mixing chamber for closing the merged fluid channel. The perturbation formations of the mixing chamber are vertically arranged vertically with respect to an inner surface.
