pH-buffers

pH-buffers zijn essentieel voor de routinematige kalibratie van pH-meters om het nauwkeurige pH-bereik van een zuur of base vast te leggen. Klaar-voor-gebruik oplossingen elimineren de tijd, kosten en besmettingsrisico’s van het mengen van buffers. pH-buffers kunnen worden gebruikt om zwak zuur, geconjugeerde base, sterk zuur, bloed-pH enz. te identificeren. Met gekleurde en kleurloze pH-bufferopties kunnen onderzoekers efficiënt de juiste indicatoroplossing kiezen voor elke test. Poederzakjes en sachets stellen laboratoria in staat geconcentreerde stoffen langer op te slaan zonder dat ze worden aangetast.
