Standaard Glasplaten ROTIPHORESE® PROclamp MINI met vaste afstandhouders, 1,0 mm

Standaard Glasplaten ROTIPHORESE® PROclamp MINI met vaste afstandhouders, 1,0 mm 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 Chemicaliën.

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.

The category is Buffers & pH solutions. The sub-category is Biological buffers (Tris, HEPES, MOPS). The catalogue is Chemicaliën.

Shelves beside this one are pH buffers & conductivity standards and Buffers (other).
