Abstract
A device for use in a multi-channel pipetting system is provided. The device includes a body, a plurality of modules mounted to the body, a plurality of pistons mounted to a piston holder for simultaneous movement of the plurality of pistons in a first direction, and a guidance assembly. Each module includes an orifice connecting to an intake chamber. A piston extends into the intake chamber for movement in the first direction. The guidance assembly includes a first rotating element, a second rotating element, a shaft connecting the first rotating element to the second rotating element, and a first track and a second track extending parallel to the first direction. The shaft extends in a second direction orthogonal to the first direction. The first rotating element is mounted to roll along the first track, and the second rotating element is mounted to roll along the second track simultaneously with the plurality of pistons.
