Description
Phosphate buffered saline pH 7.4 is a ready-to-use analytical reagent conforming to Reag. Ph. Eur. 4.1.3 for isotonic phosphate-buffered saline conditions at pH 7.4. Density is approximately 1 g/cm³ and the boiling point is greater than 100 °C, giving clear physical reference points for laboratory handling and process planning. Supplied in a 1 l plastic bottle, the solution supports sample rinsing, dilution, instrument checks and pharmacopoeial procedures that call for PBS-type media within European Pharmacopoeia chapter 4.1.3. This special buffer from manufacturer Carl ROTH is positioned for analytical chemistry environments that need standardised saline buffering at near-physiological pH without on-site preparation. It fits quality-control, research and method-development settings where reproducible ionic strength and pH stability are essential. The ready-to-dispense format streamlines daily workflows, and the 1 l pack size provides a practical balance between bench convenience and continuous laboratory demand for phosphate buffered saline applications.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffered saline pH 7.4, Reag. Ph. Eur. 4.1.3, 4005000, 1 l, plastic 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.
