General description

The boric acid/potassium chloride/sodium hydroxide buffer solution is gravimetrically prepared using high-quality reagents in high-purity water. It is produced, calibrated, and certified at a registered laboratory according to DIN EN ISO/IEC 17025. Its pH value of 10.00 at 20°C is analyzed using a combined glass electrode following a 5-point calibration method, in accordance with DIN 19268, against certified primary reference standards as per DIN 19266.

Application

The buffer solution finds its use in various analytical procedures to calibrate, qualify, and monitor the pH measuring instruments.
