Abstract
A method for preparing a volume of blood for cellular analysis in a hematology instrument includes the step of gently mixing the blood sample with a reagent and/or diluent using a stream of air. Preferably, the air stream is directed at the liquid(s) to be mixed at a relatively steep angle, preferably less than about 10 degrees from the normal to the liquid surface. A mixing vessel adapted for use in a hematology instrument for carrying out the method of the invention comprises a cap that supports an air jet for directing the air stream at an angle in keeping with the method of the invention.
