Description
La solution tampon pH 10 ±0.01 (20 °C) est un tampon d'étalonnage prêt à l'emploi de la ligne ROTI®Calipure, teinté en bleu pour une reconnaissance visuelle aisée à la paillasse. Spécifié à 20 °C avec une tolérance étroite de ±0.01 unités de pH, il prend en charge l'étalonnage et la vérification précis des électrodes dans les plages de mesure alcalines. La densité est de 1.008 g/cm³ et le point d'ébullition est d'environ 100 °C. Ce tampon du fabricant Carl ROTH aide à maintenir des conditions de mesure traçables lors des séquences d'étalonnage multipoint et des contrôles quotidiens des performances des électrodes. La teinte bleue réduit les confusions entre des tampons de valeurs de pH nominales différentes lorsque plusieurs étalons sont utilisés simultanément. Idéal pour les laboratoires qui exigent un point de référence alcalin stable pour la détermination potentiométrique du pH et les mesures associées de propriétés physiques.
Cet article fait partie de tampons pH & étalons de conductivité, dans Tampons & solutions pH.

Questions about Solution tampon pH 10 ±0.01 (20 °C), ROTI®Calipure, teintée en bleu, 250 ml
What is this article?
Solution tampon pH 10 ±0.01 (20 °C), ROTI®Calipure, teintée en bleu, 250 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in tampons pH & étalons de conductivité, inside Tampons & solutions pH, 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 Tampons & solutions pH. The sub-category is tampons pH & étalons de conductivité. The catalogue is Produits chimiques.
Shelves beside this one are Tampons biologiques (Tris, HEPES, MOPS) and Tampons (autres).
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.
