pH buffer solutions made by Scharlau.

- Density: ~ 1,00 g/cm3 - Solub. in water: (20 ºC): miscible - Tariff number: 3822 00 00 00 - Applications: in buffer solutions. SPECIFICATIONS pH at 20 �ºC: 4,00 specification range: 3,99 - 4,01 uncertainty : ± 0,01 Composition per litre is 10,2 g Potassium hydrogen phthalate. Contains preservative. 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. 0: 4,01 5: 4,00 10: 4,00 15: 4,00 20: 4,00 25: 4,01 30: 4,02 35: 4,03 40: 4,04 45: 4,05 50: 4,06
