Description
ROTI®fair PBS 7.4 is a ready-to-dissolve phosphate-buffered saline preparation supplied as a pouch that yields 100 l of working buffer at pH 7.4. Designed for biochemistry and molecular biology workflows, it supports routine buffering steps in blotting, Western blot and ELISA, as well as blocking and immunodetection protocols where a stable physiological salt environment is required. Each pouch delivers a consistent PBS formulation once reconstituted, helping laboratories prepare large buffer volumes with minimal weighing and handling. The product is offered as one unit in a box and has a net weight of 0,138 kg, making it practical for high-throughput or shared core facilities that consume substantial buffer stocks. Manufactured by Carl ROTH, ROTI®fair PBS 7.4 fits protein isolation, wash and dilution steps across life-science applications. Simply dissolve the pouch contents according to laboratory practice to obtain the stated volume of PBS 7.4, then use the buffer for sample preparation, membrane washing or immunoassay workflows that depend on controlled ionic strength and neutral pH.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about ROTI®fair PBS 7.4, for 100 l / pouch, 1 unit(s), box
What is this article?
ROTI®fair PBS 7.4, for 100 l / pouch, 1 unit(s), box 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.
