Abstract:
(EN) A turbidimeter standard ampule is described, including: a main part (202) composed of glass and containing therein a formazin solution comprising a formazine polymer diluted in a solvent; the main part including a lens positioned in a bottom edge thereof and permitting entry of light from a turbidimeter, the main part having glass sides and permitting redirected light to exit the glass sides for detection by a photodetector of the turbidimeter; an upper part (201) composed of glass and being attached to the main part; and an opaque cap (205) on the upper part, the opaque cap blocking light from entering the upper part of the ampule.
(FR) L’invention décrit une ampoule normalisée de turbidimètre, incluant : une partie principale (202) composée de verre et contenant une solution de formazine constituée d'un polymère de formazine dilué dans un solvant ; la partie principale incluant une lentille positionnée sur son bord inférieur et permettant l’entrée de lumière émise par un turbidimètre, la partie principale ayant des côtés en verre et permettant à la lumière redirigée de quitter les côtés de verre pour la détection par un photodétecteur du turbidimètre ; une partie supérieure (201) composée de verre et reliée à la partie principale ; et un bouchon opaque (205) sur la partie supérieure, le bouchon opaque empêchant la lumière d’entrer dans la partie supérieure de l’ampoule.
