Scope note: Sustancias que se emplean para la detección, la identificación, el análisis, etcétera, de enfermedades o procesos químicos, biológicos o patológicos. Los indicadores son sustancias que cambian de aspecto físico (por ejemplo, de color) al acercarse o al alcanzar el punto final de una titulación química, como en el paso entre la acidez y la alcalinidad. Los reactivos son sustancias que se emplean para detectar o determinar (especialmente para el análisis) otra sustancia a través de medios químicos o microscópicos. Existen los siguientes tipos de reactivos: precipitantes, disolventes, OXIDANTES, REDUCTORES, fundentes y colorimétricos.

Scope note: Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499)
