Abstract
An improved and unique mixing technique particularly useful as part of the process for the clinical analysis of liquid biological samples is described. The sample is placed in a cuvette along with a reagent and a diluent. The top (opening) of the cuvette is squeezed (reduced in size) and an air jet is directed against the liquid surface formed in the cuvette adjacent the junction of the liquid surface with the wall of the cuvette to create a vortex to produce thorough mixing of the contents of the cuvette and substantially prevent any splashing of the liquid contents.
