Sodium phosphate buffer solution pH 8.0 0,02 M is a ready-to-use analytical buffer for laboratory work that requires a defined alkaline phosphate system. The aqueous preparation is specified at 0,02 M and pH 8.0 and is designated Reag. Ph. Eur. 4.1.3. Manufacturer data list a density of approximately 1 g/cm³ and a boiling point of 100 °C, supporting predictable handling under standard bench conditions. Supplied in a 1 l plastic pack from manufacturer Carl ROTH, this sodium phosphate buffer suits analytical chemistry and quality-control settings where Ph. Eur. 4.1.3 buffer reagents are called for. The ready solution can be used directly in procedures that specify a 0,02 M phosphate buffer at pH 8.0, avoiding in-house dilution from concentrated stocks. It belongs to the specialised pH-buffer solutions group used for stable pH control during sample preparation, method work, and routine instrumental analyses. The stated physical properties aid process planning and documentation, while the 1 l plastic format is practical for regular laboratory consumption. Clear alignment with Reag. Ph. Eur. 4.1.3 helps laboratories record reagent identity within validated analytical workflows.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Sodium phosphate buffer solution pH 8.0 0,02 M
What is this article?
Sodium phosphate buffer solution pH 8.0 0,02 M 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.
