Sodium Phosphate Dibasic

High-Purity Sodium Phosphate DiBasic for Scientific Applications IBI Sodium phosphate acts as a crucial buffering agent in Phosphate-Buffered-Saline(PBS) typically using a mixture Of sodium phosphate dibasic (Na2HPO4) and monobasic (NaH2PO4) or potassium-based counterparts to maintain a stable Physiological pH around 7.4. It works alongside NaCl to ensure the solution is isotonic and non-toxic to cells. Buffering Agent Sodium phosphate, often in conjunction with potassium phosphate, maintains a constant pH in biological studies, preventing drastic pH changes in cell culture.
