The present disclosure provides a device that includes a base comprising a substrate having a first major surface, a pressure sensitive adhesive adhered to at least a portion of the first major surface, a polymeric cover film coupled to the substrate via the adhesive, a plurality of isolated closed compartments disposed between the substrate and the cover film, and an aqueous liquid disposed in two or more of the closed compartments. The cover film is a composite film comprising ethylene vinyl acetate copolymer, a linear copolymer of ethylene and a higher alkene, and a tackifier. Each compartment of the plurality is defined by a seal that prevents liquid communication with at least one other compartment of the plurality. Methods of using the device for partitioning a sample, for analyzing a sample, and for culturing a microorganism are also provided.
