According to the invention there is a microfluidic chip (1) that includes at least two layers (10) forming a stack of layers, each layer of which has at least one flow channel (14); a bore (16) extending through the layers and communicating with a plurality of flow channels; and a valve (20), which has a shaft (22) with a recess (222) in a side of the shaft for fluid to flow through. The shaft is rotatably mounted in the bore, and has a first position in which the recess is aligned with each of at least two flow channels of the plurality of flow channels thereby providing a flow path between said at least two flow channels, and a second position in which the recess is unaligned with at least one of said at least two flow channels the flow path between said at least two flow channels thereby being closed. This allows a fluid flow path between two flow channels to be open and closed by rotation of the shaft so that fluid in the microfluidic chip can be redirected to allow the chip to have greater capability and by using a minimal amount of space on the chip to do so. |
