Description
Phosphate buffer solution pH 7.0 R5 is a ready-to-use analytical buffer conforming to Reag. Ph. Eur. 4.1.3 under reference 4011400. Formulated for laboratories performing pharmacopoeial and general analytical work, it delivers stable pH control at the neutral value of 7.0 required by many standardised procedures. With a density of approximately 1 g/cm³ and a boiling point of 100 °C, the aqueous solution behaves predictably during heating, transfer and routine laboratory handling. The 1 l plastic pack size is practical for daily use in titration, sample preparation, calibration support and quality-control applications that call for European Pharmacopoeia-compliant reagents. Buffers in the Ph. Eur. 4.1.3 series assist in maintaining defined pH and ionic strength throughout multi-step analytical sequences. Available from manufacturer Carl ROTH as part of the specialised pH-buffer solutions portfolio, this product fits smoothly into regulated and research laboratory workflows. The ready-to-use presentation shortens preparation time and supports consistent performance across successive analytical runs and method checks.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Phosphate buffer solution pH 7.0 R5
What is this article?
Phosphate buffer solution pH 7.0 R5 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.
