ABSTRACT:
Methods are provided for the controlled simultaneous dispensing of several fine powders into microcontainers which containers are used subsequently for clinical determinations. The method includes sifting the fine powders individually to render the individual particles of each powder to be the same size, and then combining them for the subsequent dispensing procedures. The method contemplates, in addition, the reduction of the individual particles of some powders to provide the equal size requirements, before combining with one or more other powders for the subsequent controlled dispensing procedures.
