Description
Formulées afin de fournir des dosages de pH précis, ces solutions tampon qui sont standardisées contre des échantillons de référence certifiés NIST, sont idéales pour l'étalonnage des électrodes et des compteurs pH. Les tampons sont à code couleur pour éviter les erreurs et sont précis à ±0,02 pH à 25°C. Chaque tampon contient un agent conservateur/inhibiteur de moisissure et un couvercle à conditionnement sous pellicule rétractable pour éviter la contamination et les fuites. Des graphiques de compensations de température sont comprises avec chaque solution tampon. La durée de conservation des solutions tampon est de 1 an.

Great Product DOESN'T COME IN BOTTLES
Ph solution worked as advertised but was disappointed that the solution came in UN-resealable bags. I was under the impression they were in bottles.
