Sörensen pH 7.38 phosphate buffer is an aqueous solution of potassium dihydrogen phosphate and di-sodium hydrogen phosphate dihydrate. This buffer is used to keep the pH stable in various applications.

The main uses of this buffer are in biochemistry, molecular biology and analytical chemistry. Here it is used to stabilize enzymes, proteins and other biological samples by maintaining the pH in the optimal range. It is also used in cell culture to ensure optimal growth conditions for cells.

The chemical operation of the phosphate buffer is based on the buffer system created by the equilibrium between the acidic potassium dihydrogen phosphate and the basic di-sodium hydrogen phosphate dihydrate. This equilibrium allows the buffer to both absorb and release protons, stabilizing the pH. The buffer capacity here depends on the relative concentration of the two salts.

The special suitability of the Sörensen pH 7.38 phosphate buffer lies in its nearly neutral pH, which is suitable for many biological and chemical applications. Its ability to maintain a constant pH allows the structure and function of enzymes and proteins to be maintained and protects sensitive samples from damage due to pH fluctuations.

Overall, Sörensen pH 7.38 Phosphate Buffer is an important solution for stabilizing pH levels in biological and chemical applications. Its chemical properties and the balance of salts it contains allow effective buffering and ensure optimal conditions for enzymes, proteins and cell cultures.
