Abstract
The invention provides multichannel pipette heads and autopipettors for loading, measuring, transporting and dispensing, particularly from one micro-plate to another. An exemplary multichannel pipette head comprises a pump housing, pistons, a drive plate, an aspiration drive and bearing rails, wherein the pump housing comprises chambers adapted to receive the pistons, the pistons each comprise a shaft, the drive plate retains the pistons and translocates the piston shafts through the chambers, the aspiration drive translocates the drive plate along the bearing rails which pass through the drive plate and attach to the pump housing.
Claims20
A multichannel pipette head detachable from, and adapted for coupling to, a pipette head attachment assembly of an autopipettor, said pipette head comprising a pump housing, pistons, a drive plate and an aspiration drive, wherein the pump housing comprises chambers adapted to receive the pistons, the pistons each comprise a shaft, the drive plate retains the pistons and translocates the piston shafts through chambers, the aspiration drive translocates the drive plate relative to the pump housing, wherein the pistons each further comprise a proximal end ball and the drive plate retains the end ball of each piston, allowing the piston to move in two axes of rotation and in three translational axes of motion.
A multichannel pipette head detachable from, and adapted for coupling to, a pipette head attachment assembly of an autopipettor, said pipette head comprising a pump housing, pistons, a drive plate and an aspiration drive, wherein the pump housing comprises chambers adapted to receive the pistons, the pistons each comprise a shaft, the drive plate retains the pistons and translocates the piston shafts through chambers, the aspiration drive translocates the drive plate relative to the pump housing, and further comprising a latch for releasing an integrated electromechanical coupling comprising a suspension bracket and an electronic connector, which together operatively join the pipette head to the autopipettor.
