Abstract
An air knife is positioned to direct a stream or blast of air across the tip of a sample probe as it is withdrawn from a cuvette containing a reagent, diluent, and patient sample solution. After the probe is flushed with diluent, the air knife drives any droplets of diluent fluid off the probe tip into the cuvette and thereby prevents contamination or dilution of the sample material in the sample containers.
