Abstract
A multi-function dispense head operable by a single motor. The dispense head includes a pipette housing having carriage driven pipette rods and carriage driven pistons and a wash/ejector head movable by the pistons. The carriage is attached to the pipette rods and vertically moves the rods through the pipette housing as needed for various pipette functions. The pistons are pushed into movement by the carriage and, in a lower position, into contact with a lower ledge along a bottom portion of the movable head forcing the lower ledge downwardly to eject pipette tips. The pistons also move the wash/ejector head when the movable head performs a wash function.
