Buffere og standarder

Hydrogenionbuffere omfattende en blanding af en svag syre og dens konjugatbase eller omvendt og anvendt til at stabilisere pH; også fortyndingsmidler, vaskeopløsninger og standardværdiopløsninger, der anvendes til en bred vifte af videnskabelige kalibreringsformål.

De buffere, der bruges til at kalibrere pH-målere, kan være certificeret og/eller sporbare til National Institute of Standards and Technology (NIST). Disse buffere kan også være farvekodede for nem identifikation:

  • Rød: pH 4,0 Gul:
  • pH 7,0 Blå:
  • pH 10,0
