Abstract

Filtration apparatus is provided which enables a plurality of liquids to be filtered simultaneously. The apparatus basically comprises a tube adapted to be secured to a source of negative pressure, the tube having a plurality of upstanding inlets, each of which is adapted to receive a filtration paper holder. Liquid storage cylinders are adapted for mounting on the upper ends of the filtration paper holders so that liquid contained therein may be withdrawn through the filtration papers and into the tube. At least one filtrate collector is provided for optional removable mounting between at least one of the upstanding inlets and an associated filtration paper holder to collect a predetermined volume of the filtrate before the remainder of the filtrate passes down into the tube.
