Zusammenfassung:An automatic pipetting system for pipetting a measured micro-quantity of reagent into a reaction cup, in which the pipetter is lowered into a reagent bottle, a predetermined amount of reagent drawn in using a positive displacement pump, the pipetter withdrawn from the reagent bottle through an irrigated wiping sponge to accurately control the drop of reagent at its tip, rotated to a position over the cup and lowered thereinto after which the displacement pump expels a measured amount of reagent.
