Buffertar och standarder

Vätejonbuffertar innefattande en blandning av en svag syra och dess konjugatbas eller vice versa och som används för att stabilisera pH; även spädningsmedel, tvättlösningar och standardlösningar som används för ett brett spektrum av vetenskapliga kalibreringsändamål.

Buffertarna som används för att kalibrera pH-mätare kan vara certifierade och/eller spårbara till National Institute of Standards and Technology (NIST). Dessa buffertar kan också vara färgkodade för enkel identifiering:

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