Identification
Taric code: 3822 00 00
Specifications
pH at 20 °C…………………………………………..8,00
uncertainty ± 0,01
Composition per litre is 3,095 g Boric acid,3,728 g Potassium chloride and approx. 40 ml NaOH 0,1N.
Standard buffer solutions are prepared using gravimetric and volumetric procedures. The batch value is determined by measurement with a combination glass electrode against five-point calibration according to DIN 19268. This pH buffer solution is traceable to Standard Reference Material from NIST
