摘要

Pipette delivery system (10) to deliver smallest volume fluid samples has an adjustment mechanism (42) to set orientation and alignment. The assembly has a base plate (40) and adjustable counter plate (28) with a mounting pin (58) between them to give a tilting point (64) for the counter plate against the base plate when spring fitted (56) limit stops (48,50) are set to align the pipette on the X,Y directions.
