pH buffere
pH-bufferopløsninger er essentielle til rutinemæssig kalibrering af pH-metre for at opnå nøjagtige pH-områder af syre eller base. Færdiglavede opløsninger eliminerer tid, omkostninger og kontamineringsrisici ved at blande buffere. pH-buffere kan bruges til at identificere svag syre, konjugeret base, stærk syre, blodets pH osv. Med både farvede og farveløse pH-bufferoptioner kan forskere effektivt vælge den korrekte indikatoropløsning til enhver test. Pulverposer og pakker giver laboratorier mulighed for at opbevare de koncentrerede stoffer i længere tid uden at blive påvirket.
