Automatic reagent dispenser.

摘要

Method and apparatus for automatically pipetting reagents which avoid contamination of the reagents by moving an aspirating arm in the X, Y and Z directions to a selected reagent bottle, engaging a pipette tip situated in the cap of the reagent bottle, aspirating reagent, moving the tip out of the reagent bottle and, without passing over any other reagent bottles or non-selected cuvettes, into a selected cuvette and ejecting reagent into that cuvette. The pipette tip is then returned to the cap of the bottle before the aspirating arm moves to the next reagent.
