Abstract
A filter arrangement with a top element and a bottom element and a filter element therebetween captures oversized particles on the upper surface of the filter element and tangentially rinses these particles using an elution fluid to provide a concentration of particles in a relatively low volume of fluid for further analysis. A configuration using a slider valve may also be utilized. Additionally, an arrangement of supply and receiving containers may be used to minimize the number of containers required. A mass flow meter may be incorporated to measure the flow of elution fluid. Finally, a wash stage of the filtering process may be used to introduce stain onto the particles for further analysis, such as that associated with Gram staining and these stained particles may be further analyzed.
