Tamponi pH

I tamponi tampone pH sono essenziali per la calibrazione di routine dei pH-metri al fine di catturare un intervallo accurato di pH di acidi o basi. Le soluzioni pronte all’uso eliminano il tempo, le spese e i rischi di contaminazione della miscelazione dei tamponi. I tamponi pH possono essere utilizzati per identificare acidi deboli, basi coniugate, acidi forti, pH del sangue ecc. Con le opzioni di tamponi pH colorati e incolori disponibili, i ricercatori possono selezionare in modo efficiente la soluzione indicatrice corretta per qualsiasi test. I cuscinetti e le bustine in polvere consentono ai laboratori di conservare le sostanze concentrate per periodi più lunghi senza essere compromessi.
