Harris Uni-Core stoten

Harris Uni-Core stoten is the article on this page. Luminix Health distributes Qiagen for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Labor- und Industriechemikalien.

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 Labor- und Industriechemikalien.

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