Beschrijving
Bufferoplossing pH 9 ±0.01 (20 °C) is een boraatvrije ROTI®Star-kalibratiestandaard, geformuleerd voor nauwkeurige bepaling van de pH-waarde bij 20 °C. De tolerantie van ±0.01 ondersteunt betrouwbare elektrodekalibratie, systeemgeschiktheidscontroles en routinematige analytische controle waar een alkalisch referentiepunt nodig is zonder boraat. Gegevens van de fabrikant vermelden een dichtheid van 1.006 g/cm³ en een kookpunt van 100 °C, wat een waterige matrix weerspiegelt die geschikt is voor de dagelijkse laboratoriumpraktijk. Het product is Deze boraatvrije buffer van fabrikant Carl ROTH past bij workflows die de voorkeur geven aan boraatvrije media en tegelijk het ROTI®Star-specificatieprofiel behouden. Typische toepassingen omvatten de bepaling van fysische eigenschappen, methodeverificatie en instrumentkalibratie in onderzoeks-, industriële en onderwijslaboratoria. Gebruikt u volgens standaard laboratoriumprocedures en raadpleegt u het veiligheidsinformatieblad vóór hantering. De gedefinieerde pH, de boraatvrije samenstelling en de vermelde dichtheid ondersteunen consistente kalibratie zonder interne bufferbereiding.

Questions about Bufferoplossing pH 9 ±0.01 (20 °C), ROTI®Star, boraatvrij, 500 ml, kunststof
What is this article?
Bufferoplossing pH 9 ±0.01 (20 °C), ROTI®Star, boraatvrij, 500 ml, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in pH-buffers & geleidbaarheidsstandaarden, inside Buffers & pH-oplossingen, in Chemicaliën.
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.
