Abstract
An integrated motor cartridge (2) for connection to and for use in a pipetting system comprises a housing (4); a guide tube (14); a piston (16) provided with a plurality of permanent magnets (18), the piston having a pressure tube facing side and a pressure tube distal side, the piston being arranged in the guide tube and the piston having at least one seal (24) with respect to the guide tube; and a coil assembly (20) by means of which the piston can be moved in the guide tube when power is supplied to the coil assembly; wherein the guide tube, the piston and the coil assembly are arranged in the housing. The integrated motor cartridge further comprises a pressure tube connection (6) by means of which the guide tube, on the pressure tube facing side of the piston, can be connected to a pressure tube of the pipetting system in a gastight manner; and a power connection (8) which is coupled to the coil assembly and adapted to be coupled to a power supply arranged outside of the integrated motor cartridge; wherein the integrated motor cartridge can be introduced into and removed from the pipetting system as a unit.
