Abstract
An analysis apparatus for performing biochemical analysis of a sample using nanopores comprises: a sensor device that that supports plural nanopores, reservoirs holding material for performing the analysis; a fluidics system; and plural containers for receiving respective samples, all arranged in a cartridge that is removably attachable to an electronics unit arranged to generate drive signals to perform signal processing circuit to generate output data representing the results of the analysis. The fluidics system supplies samples selectively from the containers to the sensor device using a rotary valve. In one valve, a stator defines a plurality of first ports arranged around the rotational axis and a collection chamber extending in around the axis of rotation in communication with a second port. A rotor provides a passage extending between the collection chamber and a position in communication with any one of the plurality of first ports. In another valve a stator defining a plurality of first ports in an annular surface facing the rotational axis, and a rotor is mounted inside a liner arranged between the annular surface of the stator and a facing annular surface of the rotor.
