ABSTRACT:
An automatic filtering apparatus which provides an aliquot of filtrate of a particular quantity desired is provided. A solid-liquid mixture is introduced to a filter means under positive air pressure to provide the liquid filtrate. The filtrate flows into a receiving means defining the volume of the particular quantity desired. Excess filtrate flows into an overflow reservoir and out a waste line connected thereto. The filtrate in the receiving means can be transferred into a delivery means. Advantageously, a three-way stop-cock is disposed between the filter receiving means and delivery means and the flow paths are determined by the position of the stop-cock.
