Abstract

See full text

An apparatus and method to perform multiple filtration steps with a modular filtration apparatus and single cycle. A stackable modular filter cup has features to allow stacked cups to be separated without the need for substantial effort yet without diminishing the effect of vacuum assisted filtration. Each cup is formed with a slip seal segment and/or a series of substantially vertical channels or ridges on an inner or outer wall to reduce surface contact between nested filter cups.
