A multichannel pipette has downwardly depending tip cones to receive disposable tips which have free ends. Adjacent tip cones, and thus the disposable tips, are spaced apart a first distance, which is referred to as the intra-channel spacing. An adapter changes the intra-channel spacing of the free ends of the pipette tips. The adapter has a series of apertures therethrough, and the distance (center-to-center) between adjacent apertures differs from the first distance. The disposable tips are inserted through the adapter to change the intra-channel spacing between the free ends of the tips, either by spreading out or contracting the spacing between the free ends of the tips.
