Abstract
A fluid cup is provided for use with a cup support having a cup-receiving receptacle and a drain. The cup is adapted for use with a pipette probe which may introduce contaminants into the fluid, for example a dilutant fluid, in the cup. The cup has a lower cup portion and a cap, with a notch or other overflow element being provided near the top of the lower cup portion. Diluent fluid is introduced near the bottom of the lower cup portion after each probe entry, creating a fluid flow pattern which flushes any contaminant from the cup through the notch without requiring the use of a large fluid volume.
