<p>A method and apparatus for accurate pipetting of small liquid volumes wherein one or more pipettes are at least partly enclosed in a thermostatically controlled space in a single pipetting-incubating station. Sample reagent or reaction mixture test tubes or other container, and shaker or storage sections for components may be included in the pepetting-incubating station, whereby pipetting, shaking, and storing of samples and reaction mixtures is carried out centrally in one single pipetting-incubating station in a pre-determined manner. The apparatus may include a multistep, multiple pipette having a piston and an electric motor for movement of the piston. A photodiode and a light source may cooperate to determine the extent to movement of the piston. The electric motor may be a stepping motor.</p> |
