Description
ROTI®CELL PBS is a sterile phosphate-buffered saline prepared without calcium and magnesium for cell-culture applications. Supplied ready-to-use under the CELLPURE® quality concept, the solution has a density of approximately 1 g/cm³ and a boiling point around 100 °C. It is intended as a general reagent for rinsing, diluting and handling cells where a balanced, calcium- and magnesium-free buffer is required. supports routine work in cell-culture laboratories, including media preparation steps, cell washing and sample handling under sterile conditions. Offered from manufacturer Carl ROTH within the ROTI®CELL range, this PBS formulation provides a convenient, ready-to-dispense buffer for everyday cell-biology workflows. Its sterile, Ca/Mg-free composition suits protocols that demand controlled ionic conditions without divalent cations, helping maintain consistency across general cell-culture procedures and related laboratory applications.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about ROTI®CELL PBS, sterile, w/o Ca/Mg, 500 ml, plastic
What is this article?
ROTI®CELL PBS, sterile, w/o Ca/Mg, 500 ml, 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.
