产品说明
一般描述
The blue-colored boric acid/potassium chloride/sodium hydroxide buffer solution is gravimetrically prepared using high-quality reagents, in accordance with DIN EN ISO/IEC 17025. Its pH value of 9.00 at 20℃ 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.
应用
The buffer solution is meant to be used as a calibration standard for pH measuring instruments or pH electrodes and as a control for measuring the pH of solutions.
