AUTOMATIC POWDER DISPENSING METHODS AND APPARATUS ABSTRACT OF THE DISCLOSURE Methods and apparatus are provided for dis- pensing, simultaneously and automatically, a plurality of small quantities of powder under im- proved conditions of control. The arrangement is such that precise amounts of micro quantities of hard-to-handle powder may be dispensed into con- tainers such as blood collection tubes. Included herein is a brush mechanism that reciprocates over a plate in a controlled manner, for sweeping a slug of powder deposited automatically on the plate in a controlled manner through a number of openings in the plate, and into an equal number of containers. The openings are dimensioned and configured to cooperate with the sweeping action of the brush, so that a desired precise quantity of powder is deposited through each opening into the waiting containers.
