Description
ROTI®fair PBS 7.2 is a phosphate-buffered saline tablet formulation for biochemistry and molecular biology, with each tablet preparing 1000 ml of buffer at pH 7.2. Tablet dosing simplifies buffer make-up for protein biology, purification and isolation work, reducing weighing errors and speeding routine preparation. Physical data include a density of 2,01 g/cm³ and a boiling point of 1413 °C. The pack provides ten units in blister packaging and has a net weight of 0,051 kg, convenient for individual benches or small-volume workflows. Offered by Carl ROTH within the ROTI®fair range, these tablets support wash, dilution and equilibration steps that require a stable PBS environment slightly below physiological pH. Dissolve one tablet in water to the stated volume to obtain PBS 7.2, then apply the buffer in protein isolation and related life-science methods. The blister presentation keeps tablets separated and easy to dispense, helping maintain consistent batch-to-batch buffer preparation across repeated experiments.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about ROTI®fair PBS 7.2, for 1000 ml / tablet, 10 unit(s), blister
What is this article?
ROTI®fair PBS 7.2, 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.
