<p>A pipettor (10) having a plurality of tip fittings (7) slidable in a track (82) and coupled by a linkage (89) that maintains a uniform spacing between each tip fitting (7). Preferably, the linkage (89) is a pantographic linkage. The spacing between tip fittings (7) is adjusted by use of a stop (75). An actuating rod (11) carrying a knob (12) on a distal end thereof is used to change the spacing between the tip fittings (7).</p> |
