Abstract
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 the at least two flow channels, and a second position in which the recess is unaligned with at least one of the at least two flow channels the flow path between the 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.
