Abstract
The present disclosure relates to devices and methods for preparing a filtered solution from slurry for lateral flow testing of analytes of interest in agricultural or environmental samples. A porous frit is located adjacent to an outlet of a vessel containing slurry, and positive pressure is applied to the volume enclosed by a vessel body of the vessel to cause the slurry to pass through the porous frit and become a filtered solution that exits the outlet of the vessel. Devices and methods described herein allow more rapid, cleaner, and inexpensive production of filtered samples than conventional methods.
