Buffer solution pH 9.0 R1 is a ready-to-use analytical reagent buffer prepared in accordance with Reag. Ph. Eur. 4.1.3 for controlled alkaline pH work in pharmaceutical and general laboratory practice. It delivers a defined pH of 9.0 and is intended for applications that rely on European Pharmacopoeia reagent specifications, including instrument checks, sample conditioning and method support in analytical chemistry. Physical data indicate a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with an aqueous buffer matrix. The solution is supplied in a practical 1 l plastic pack that suits routine bench use and quality-control workflows. Reference designation 4007100 identifies this grade within the specialised pH-buffer solutions Ph. Eur. 4.1.3 range. From manufacturer Carl ROTH, the formulation supports laboratories that need a stable, clearly specified alkaline buffer without on-site preparation. Its liquid presentation and unit volume facilitate straightforward handling, storage organisation and replenishment in analytical suites working under pharmacopoeial reagent requirements.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution pH 9.0 R1
What is this article?
Buffer solution pH 9.0 R1 is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, 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.
