VORRICHTUNG UND VERFAHREN ZUR DURCHFÜHRUNG VON NUKLEINSÄUERETESTS MITTELS TEMPERATURZYKLEN

摘要

The method for thermal cycling of nucleic acid assays includes a blended fluid stream produced from a plurality of constant velocity, constant volume, constant temperature fluid streams wherein to provide a variable temperature, constant velocity, constant volume fluid stream which is introduced into a sample chamber for heating and cooling samples contained therein. By diverting and altering the ratio of the constant temperature fluid streams relative to one another, the blended fluid stream is rapidly variable in temperature, providing for almost instantaneous temperature change within the environment defined by the sample chamber.
