Abstract
There is provided an assay fluid delivery system comprising an array of fluid reservoirs (62), each of which is selectively actuatable to deliver a respective fluid to a fluid channel structure; and a fluid delivery control system (50) comprising a plurality of reciprocally mounted actuators, each associated with a respective reservoir and being movable between a retracted position and an actuating position at which it causes fluid to be delivered from the corresponding reservoir, a plurality of cams (22) with different profiles mounted on a common, rotatable cam shaft (6), each cam being engaged with a respective one of the actuators whereby rotation of the cams causes movement of the corresponding actuators between the retracted and actuating positions, and a motor coupled to the cam shaft for rotating the cam shaft, wherein the cams are shaped relative to one another so as to cause the corresponding actuators to actuate the reservoirs in a predetermined sequence and for predetermined respective times.
