pH buffertar
pH-buffertlösningar är oumbärliga för rutinmässig kalibrering av pH-mätare för att fånga det exakta pH-intervallet för syra eller bas. Färdigberedda lösningar eliminerar tiden, kostnaderna och kontamineringsriskerna med att blanda buffertar. pH-buffertar kan användas för att identifiera svag syra, konjugerad bas, stark syra, blodets pH etc. Med färgade och färglösa alternativ av pH-buffert kan forskare effektivt välja rätt indikatorlösning för varje test. Pulverpåsar och satser gör det möjligt för laboratorier att lagra koncentrerade ämnen under längre tid utan att påverkas.
