Beschrijving
Bufferoplossing pH 10 ±0.01 (20 °C) is een gebruiksklare kalibratiebuffer uit de ROTI®Calipure-lijn, blauw getint voor eenvoudige visuele herkenning aan de werkbank. Gespecificeerd bij 20 °C met een nauwe tolerantie van ±0.01 pH-eenheden ondersteunt deze een nauwkeurige elektrodekalibratie en -verificatie in alkalische meetbereiken. De dichtheid is 1.008 g/cm³ en het kookpunt is ongeveer 100 °C. Deze buffer van fabrikant Carl ROTH helpt traceerbare meetomstandigheden te handhaven tijdens meerpuntskalibratiereeksen en dagelijkse controles van de elektrodeprestaties. De blauwe tint vermindert verwisselingen tussen buffers met verschillende nominale pH-waarden wanneer meerdere standaarden gelijktijdig in gebruik zijn. Ideaal voor laboratoria die een stabiel alkalisch referentiepunt nodig hebben voor potentiometrische pH-bepaling en verwante metingen van fysische eigenschappen.
Dit artikel maakt deel uit van pH-buffers & geleidbaarheidsstandaarden, in Buffers & pH-oplossingen.

Questions about Bufferoplossing pH 10 ±0.01 (20 °C), ROTI®Calipure, blauw getint, 250 ml
What is this article?
Bufferoplossing pH 10 ±0.01 (20 °C), ROTI®Calipure, blauw getint, 250 ml 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.

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.
