Abstract

A system and method for preparing samples to test an environmental surface for an analyte of interest. The system can include a deformable self-supporting receptacle comprising a reservoir, and a loaded substrate positioned in the reservoir of the deformable self-supporting receptacle. The loaded substrate can include a substrate and a source collected from the surface. The method can include combining the loaded substrate and a diluent in the reservoir, and agitating the loaded substrate and the diluent to form a liquid composition comprising the source and the diluent.
