Colorimetric test kit

摘要

A detection kit is used for detecting compounds and includes a magnifying lens in a cap that magnifies a surface of a color-changing detection swab when placed on the body of the detection kit. For example, the cap includes a plurality of lenses that are integrally formed in a plastic cap, and each lens magnifies the surface of a different swab.

主权项

1. A detection kit for detecting compounds, the kit comprising:
a body having an engaging end; a cap having a first end, a second end opposite of the first end, and a lens disposed on the first end, and when the cap engages the body, the second end of the cap engages the engaging end of the body of the detection kit; and a swab, disposed in the body of the detection kit and having a tip, the tip having a detection surface for detecting compounds, the detection surface extending beyond the engaging end of the body such that the detection surface is capable of making contact with a surface to be tested when the cap is removed from the body of the detection kit, and the tip is arranged within the body and in relation to the lens, wherein at least a portion of the tip is magnified by the lens when the cap is disposed on the body of the kit, wherein the swab includes at least two swabs and the lens includes at least two lenses, each of the two lenses being disposed in the cap, such that the respective surfaces of the at least two swabs are magnified by a respective one of the at least two lenses.
