ABSTRACT:
A pipetting device comprising a housing and a plurality of tubes mounted on the housing. The housing has a manifold chamber and a plurality of passages leading from the tubes, respectively, to the manifold chamber. A flexible impervious membrane extends across the passages to divide each of the passages into a first passage section and a second passage section. The first passage sections provide communication between the tubes and one side of the membrane, and the second passage sections provide communication from the other side of the membrane to the manifold chamber. A substantially incompressible flowable material, such as a liquid, fills the second passage sections and the manifold chamber. A mechanism is provided for moving the flowable material to deflect the membrane in opposite directions whereby liquid can be drawn into, and expelled from, the tubes.
