Description
ROTI®fair PBS potassium-free 7.4, rich is a phosphate-rich, potassium-free PBS buffer tablet for biochemistry and molecular biology. Each tablet prepares 1000 ml of solution at pH 7.4, supporting consistent buffer make-up when a richer phosphate background is required. Supplied as 100 tablets from manufacturer Carl ROTH, the pack weighs 0,252 kg and is suited to higher-throughput or frequently used buffer stations. The potassium-free profile helps when potassium ions must be excluded from the buffer matrix. Application areas include blotting-related work and Western blot and ELISA contexts where blocking and immunodetection buffers are prepared from PBS-type systems. Dissolving one tablet to the stated volume yields a working potassium-free PBS solution for biochemical and molecular biology protocols. The rich-in-phosphate designation distinguishes this variant within the ROTI®fair PBS potassium-free 7.4 line. It offers a practical tablet format for laboratories that need reproducible pH 7.4 PBS without potassium and with elevated phosphate content for routine immunoanalytical and related life-science procedures.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about ROTI®fair PBS potassium-free 7.4, rich, in phosphate, for 1000 ml / tablet
What is this article?
ROTI®fair PBS potassium-free 7.4, rich, in phosphate, for 1000 ml / tablet is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Lab chemicals.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
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.
