Abstract: A receptacle for detecting a targeted pathogen is provided. The receptacle includes a main body configured to accommodate reagent containing ampoules and a specimen collector, a reservoir provided at a distal end side of the main body, and a support extending through the main body in an extending direction of the receptacle. The support includes an inlet that permits passage of the specimen collector into the main body and an outlet that restrictively permits passage of the specimen collector into and out of the reservoir.

Abstract: Embodiments of the present disclosure pertain to a colorimetric system for detecting a substance, the colorimetric system that includes a first chemical container adapted for releasing a first chemical; a second chemical container adapted for releasing a second chemical; a flow modulation sheet adjacent each chemical container; and an encapsulation covering the flow modulation sheet and each chemical container, where the encapsulation comprises a window defining a target area of the filter paper such that the target area is adapted for applying the substance; where the flow modulation sheet comprises a design adapted for automatically controlling a first flow of the first chemical and a second flow of the second chemical to the target area after simultaneously releasing the first and second chemicals; and where the design comprises a first void disposed in the flow modulation sheet.
