A system and method for preparing samples for analyte testing. The sample preparation system can include a freestanding receptacle. The method can include providing a liquid composition comprising a source and a diluent, and positioning the liquid composition in a reservoir defined by the freestanding receptacle. The method can further include filtering the liquid composition to form a filtrate comprising an analyte of interest, removing at least a portion of the filtrate from the sample preparation system to form a sample, and analyzing the sample for the analyte of interest.
