Abstract

The device includes a diluent chamber having a plunger in it which is reciprocable between a first and second position for displacing a first volume when moved, and at least a first sample chamber having a plunger in it reciprocable between a first and second position for displacing a second volume when moved. The volumes are arranged to have a fixed precise ratio with respect to one another for any equal distance moved by the plungers in their chambers. A coupling device couples the plungers together for simultaneously reciprocally moving the plungers an equal distance in the chambers between first and second positions. Sample and diluent are drawn into the device, then both expelled at a common point.
