Potassium Hydrogen Phthalate (KHP) Is A Widely Used Chemical With Important Applications In Analytical And Industrial Processes. It Is Primarily Used As A Primary Standard In Analytical Chemistry For The Standardization Of Strong Bases Such As Sodium Hydroxide Due To Its High Purity And Stability. In Laboratories, It Is Commonly Used In Acid-Base Titrations To Ensure Accurate Concentration Measurements.

The certified potassium hydrogen phthalate buffer solution is gravimetrically prepared using high-quality reagents at a registered calibration laboratory. It has a pH value of 4.01 at 25 C, measured using a combined glass electrode following a 5-point calibration method. The measurement is made in accordance with DIN 19268 using reference buffer solutions compliant to DIN 19266, NIST, IUPAC, Ph. Eur, and USP. The pH value of the buffer solution heavily depends on the temperature and therefore a constant temperature must be maintained during its use.Application The buffer solution is used as a standard in analytical procedures for the calibration of pH measuring instruments or pH electrodes and as a control for the measurement of pH of other solutions.Features and BenefitsMeasured and qualified at an ISO/IEC 17025 and ISO 17034 accredited laboratoryDirectly traceable to secondary reference standard from NIST and primary certified reference standard from PTBReady-to-use solution available in 30 mL sachetsAccompanied with a detailed and batch-specific certificate of analysis (CoA) for an effective quality management systemProduct label follows the ISO Guide 31 and contains information about ordering number, article description, lot number, safety data, and expiry datePackaging material subjected to comprehensive stability studies as per ISO Guide 35Accurate up to +/- 0.02 at 25 C
