Description
La solution tampon DuraCal pH 3,06 (25 °C) est un étalon d'étalonnage de pH incolore, prêt à l'emploi, destiné à la détermination précise du pH en laboratoire. Défini à pH 3,06 mesuré à 25 °C, il constitue un point de référence acide fiable pour l'étalonnage des électrodes et des pH-mètres. La solution présente une densité d'environ 1 g/cm³ et un point d'ébullition de 100 °C, et est conditionnée en unité de 500 ml pour un poids de 0,701 kg. Chaque flacon est fourni avec un certificat Hamilton, appuyant des procédures d'étalonnage documentées. Ce tampon DuraCal du fabricant HAMILTON s'intègre aux flux de travail de détermination des propriétés physiques, de contrôle qualité analytique et de vérification routinière des instruments. Son aspect limpide et sa valeur de référence spécifiée aident les laboratoires à maintenir la cohérence des mesures au fil des étapes d'étalonnage successives. Le format pratique est adapté à une utilisation sur paillasse dans les environnements de recherche, industriels et de test nécessitant un tampon stable à pH 3,06 (25 °C) pour les contrôles de performance des électrodes et le support de méthodes.

Questions about Solution tampon DuraCal pH 3,06 (25 °C), incolore, avec certificat Hamilton
What is this article?
Solution tampon DuraCal pH 3,06 (25 °C), incolore, avec certificat Hamilton is the article on this page. Luminix Health distributes HAMILTON for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Produits chimiques.
A pH buffer for calibration has a stated pH at a stated temperature, often traceable. A conductivity standard has a stated conductivity. They are not general reagents and they should not be poured back into the bottle. The temperature of the measurement has to be the temperature on the label, or the meter has to compensate.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
Which category should I open next?
The category is Buffers & pH solutions. The sub-category is pH buffers & conductivity standards. The catalogue is Produits chimiques.
Shelves beside this one are Biological buffers (Tris, HEPES, MOPS) and Buffers (other).
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
