Application


  • pH calibration solution: A study emphasizes the crucial role of pH standard solutions in calibrating equipment for precise pH measurements in plant biology, aiding in the effective management of salinity stress in barley by adjusting pH levels of nutrient solutions (BMC Plant Biol, 2024; doi: 10.1186/s12870-024-04968-y).

  • pH buffer solution for scientific experiments: pH standard solutions are employed in advanced bone regeneration research, where precise pH control is necessary to optimize the conditions for biocompatibility and efficacy of biomaterials (Int J Biol Macromol, 2024; doi: 10.1016/j.ijbiomac.2024.131480).

  • pH measurement standard: Utilization of pH standard solutions is documented in drug testing applications, particularly in enhancing the detection sensitivity and specificity of morphine and methaDonein biofluids, highlighting the importance of accurate pH measurement in toxicological studies (Sci Rep, 2024; doi: 10.1038/s41598-024-58843-9).

  • pH reference solution for laboratory analysis: The application of pH standard solutions in cell-free expression systems for protein detection illustrates the necessity for precise pH conditions to ensure the stability and functionality of the proteins being analyzed (Sci Rep, 2024; doi: 10.1038/s41598-024-58588-5).

  • pH control solution for biotechnology research: pH standard solutions are integral in the synthesis of amino-modified magnetic covalent organic frameworks, demonstrating their application in the extraction and determination of anionic azo dyes in beverages, where pH control is crucial for process efficiency (Anal Sci, 2024; doi: 10.1007/s44211-024-00561-3).
