Description
Phosphate buffer solution pH 7.0 R7 is a ready-to-use analytical buffer conforming to Reag. Ph. Eur. 4.1.3 under reference 4015700. Designed for pharmaceutical and analytical laboratories, it maintains stable conditions at pH 7.0 for methods that specify European Pharmacopoeia reagents. The aqueous formulation exhibits a density of approximately 1 g/cm³ and a boiling point of 100 °C, supporting dependable behaviour during dilution, transfer and everyday laboratory operations. Supplied in a 1 l plastic bottle, the solution is convenient for titration, sample conditioning, instrument-related support tasks and quality-control work requiring controlled neutral buffering. Ph. Eur. 4.1.3 special buffer solutions help preserve consistent pH and ionic strength across sequential analytical steps. Offered by manufacturer Carl ROTH in its pharmacopoeial pH-buffer portfolio, the product integrates readily into regulated laboratory practice. Its ready-to-use format limits preparation time and assists laboratories in achieving reproducible results during routine testing, method verification and comparative analytical procedures.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Phosphate buffer solution pH 7.0 R7
What is this article?
Phosphate buffer solution pH 7.0 R7 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 Lab chemicals.
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.
