Labeling liquids

Abstract

A method includes identifying a liquid within a vessel using an object located in the liquid that is not attached to the vessel. The object is, for example, a metal plate inscribed with an identifier, such as the name and strength of a medical solution. The plate rests against the bottom of the vessel, and the liquid is identified by reading the name through the liquid. A method of forming a label includes inscribing a metal object configured for placement within a vessel with the name and strength of a liquid medical solution, for example, laser etching a stainless steel plate. A label includes a metal plate configured for placement within a vessel and having a name and a strength of a liquid medical solution inscribed thereon. The plate includes, for example, stainless steel, and does not include an adhesive or have a fastener interface to receive a mechanical fastener.
