Buffer solution

Descrição detalhada : The boric acid/potassium chloride/sodium hydroxide certified buffer solution is gravimetrically prepared using high-quality reagents, in accordance with DIN EN ISO/IEC 17025, at a registered calibration laboratory. Its pH value of 11.00 at 20C is measured following a 5-point calibration method, using a combined glass electrode. The measurement is made following DIN 19268 using reference buffer solutions compliant to DIN 19266, NIST, IUPAC, Ph. Eur, and USP. The pH value is strongly dependent on the temperature and therefore a constant temperature must be maintained during its use.
