Abstract

See full text

Method and apparatus for automatically pipetting reagents which avoid contamination of the reagents. The reagents are withdrawn from a reagent bottle via a pipette tip which is unique to a particular reagent. The pipette tip is moved to a cuvette where the reagent is dispensed and then returned to rest in the cap of the reagent bottle. The apparatus for carrying out the method includes a pump, pipette pick-up device, reagent bottle cap and bottle rack.
