SPECIFICATIONS
pH at 20 ºC: 1,00
uncertainty ± 0,01 Composition per litre is 0,2 g Glycine, 0,1 g Sodium chloride and about 13,1 g Hydrochloric acid concentrated.

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.
