Lactic acid 88% solution is a highly concentrated reagent used in pH adjustment applications. This 500mL solution is commonly employed in laboratory processes that require precise acidification of solutions to maintain optimal pH levels for biological or chemical reactions. Lactic acid is widely used in fermentation processes, food preservation, and in the production of lactic acid-based polymers. Its ability to lower pH without adding excess ionic strength makes it a suitable choice for sensitive biological applications, such as cell culture and enzymatic assays. This solution is often used in research laboratories, industrial applications, and bioprocessing environments.
