Description
ROTI®fair PBS potassium-free 7.4 is a buffer tablet for preparing potassium-free PBS at pH 7.4 in biochemistry and molecular biology. Each tablet is intended for 1000 ml of working solution, giving a straightforward route to a defined buffer without multi-component weighing. The product is offered as 10 tablets in blister packaging from manufacturer Carl ROTH, with a pack weight of 0,051 kg. This format suits routine bench preparation where reproducible pH 7.4 conditions are needed and potassium ions should be avoided. In life-science settings it supports protein biology workflows, including steps linked to protein purification and protein isolation reagents. Laboratories can dissolve one tablet to the stated volume whenever fresh potassium-free PBS is required for biochemical handling or molecular biology procedures. The blister presentation keeps individual tablets separated for orderly dispensing. ROTI®fair PBS potassium-free 7.4 therefore addresses everyday buffer demand in protein-oriented and general molecular work where a potassium-free PBS system at pH 7.4 is specified.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

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