Abstract
A system is provided for filtering a substance from a solution for subsequent analysis of the substance. The system has a manifold and a removable cover capable of latching onto a base defining an interior of the manifold. Apertures are formed in the cover capable of receiving columns having a filter for filtering the substance from the solution as solution is drawn through the columns into the manifold. The columns may be integrally formed to provide a set of columns. As a result, an array of apertures can receive a number of sets of columns to conduct the filtering process.
