Description
ROTI®fair PBS 7.4 is a phosphate-buffered saline tablet product for biochemistry and molecular biology, with each tablet formulated to prepare 100 ml of buffer at pH 7.4. The smaller preparation volume suits assay-scale work, parallel samples and protocols that need fresh PBS without generating large excess stocks. Density is given as 2,01 g/cm³ and the boiling point as 1413 °C. Supplied as one hundred tablets in plastic packaging with a pack weight of 0,251 kg, the format supports frequent use in protein purification and isolation laboratories. Carl ROTH manufactures this ROTI®fair PBS 7.4 variant for reliable day-to-day buffering in wash, blocking-related and sample-handling steps. Dissolve one tablet per 100 ml of water to obtain PBS 7.4, then employ the solution in life-science workflows that depend on controlled ionic strength and neutral pH. High unit count in a compact plastic pack makes the product practical for shared freezers or reagent shelves where many small buffer batches are prepared over time.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about ROTI®fair PBS 7.4, for 100 ml / tablet, 100 unit(s), plastic
What is this article?
ROTI®fair PBS 7.4, for 100 ml / tablet, 100 unit(s), plastic 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.
