Buffer PREC (50 mL)

Buffer PREC (50 mL) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Buffers (other), inside Buffers & pH solutions, in Produits chimiques de laboratoire et industriels.

These are buffer solutions and salts that are not a pH calibration standard and not a named biological buffer. The pH, the concentration and the identity of the ions are the specification. A buffer has a capacity. Diluted too far, it is only salty water.

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 Buffers (other). The catalogue is Produits chimiques de laboratoire et industriels.

Shelves beside this one are pH buffers & conductivity standards and Biological buffers (Tris, HEPES, MOPS).
