Phosphate Buffer pH 7.0

artikelbilder/Artikel_17354_Phosphatpuffer_pH.png

Phosphate buffer pH 7.0 is widely used in medical, histological and scientific laboratories. In medical diagnostics, it is preferred for stabilizing enzymes and maintaining a constant pH in biological reactions. In histology, it provides robust buffering capacity, useful in staining processes and for preservation of tissue structures.

The solution consists of di-sodium hydrogen phosphate dihydrate (Na2HPO4.2H2O), potassium dihydrogen phosphate (KH2PO4) and sodium azide (NaN3) in aqua bidest. The phosphates work together to create the buffer, with sodium azide serving as a preservative.

The chemical properties and composition of the phosphate buffer allow it to maintain a constant hydrogen ion concentration, which is essential for many scientific applications. The buffer shows resistance to pH changes caused by the addition of acids or bases.

The application enables reliable and stable experiments and analyses by maintaining a constant pH.

The molarity is 0.15 M, the osmolarity is 0.3 Osmol/L, and the buffer capacity is optimal in this pH range.
