ABSTRACT:
The present invention involves a simple, disposable, manual filtration and extraction device and method of use that provides a sample directly to an analytical method. The device is capable of providing a clarified liquid ready for analysis or disposal as appropriate for the specific analyte of interest, and is capable of capturing particulate materials and allowing for further extraction of those particles directly with the device. Once extracted, the device will deliver a liquid containing the analyte of interest to an analytical method. The filtration and extraction devise includes a pliant body having an open top end and an internal wall defining an inner chamber. A sealing mechanism is adapted to seal the open top end of the body. A gradient filter assembly including at least one filter is supported by a support assembly carried by the body. The pliant body is adapted to be squeezed by a user's fingers so as to impart a positive pressure in the chamber sufficient to cause a fluid in the chamber to flow through the filter assembly.
