Citrate Phosphate Buffer (Mcilvaine Buffer, pH 2.5)

Citrate Phosphate Buffer (McIlvaine Buffer, pH 2.5) provides a ready-to-use solution for experiments that require an acidic, controlled-pH environment. The McIlvaine buffer system combines citric acid and phosphate components to support pH control across a range of laboratory applications. This formulation is intended for researchers working with acid-dependent biochemical reactions, analytical methods, and other procedures where maintaining the specified pH is important. Select this buffer when a pH of 2.5 is appropriate for your experimental requirements.
