Description
ROTI®fair PBS 7.4 is a phosphate-buffered saline tablet reagent for preparing buffer at pH 7.4, with each tablet intended for 1000 ml of working solution. Ten tablets are supplied in blister packaging for biochemistry and molecular biology use, including blotting-related steps such as Western blot and ELISA blocking and immunodetection where PBS-based buffers are routinely applied. Available figures give a density of 2,01 g/cm³ and a boiling point of 1413 °C. The one-litre-per-tablet design streamlines preparation of larger buffer volumes without weighing individual salts, supporting consistent washing, dilution and detection workflows. These tablets from manufacturer Carl ROTH offer a straightforward reconstitution route for laboratories that repeatedly need litre-scale PBS 7.4. The blister pack of ten units balances stock convenience with controlled consumption for protein biology and immunodetection protocols. Ready-to-dissolve tablets help maintain batch-to-batch uniformity in applications that rely on stable physiological buffer conditions.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about ROTI®fair PBS 7.4, for 1000 ml / tablet, 10 unit(s), blister
What is this article?
ROTI®fair PBS 7.4, for 1000 ml / tablet, 10 unit(s), blister 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.
