Pufry pH

Pufry pH jsou nezbytné pro rutinní kalibraci pH metrů, aby zachytily přesný rozsah pH kyselin nebo zásad. Připravené roztoky připravené k použití eliminují čas, náklady a riziko kontaminace spojené s mícháním pufrů. Pufry pH lze použít k identifikaci slabých kyselin, konjugovaných zásad, silných kyselin, pH krve atd. Díky barevným a bezbarvým možnostem pH pufrů mohou výzkumníci efektivně vybrat správný indikační roztok pro jakýkoli test. Práškové polštářky a sáčky umožňují laboratořím uchovávat koncentrované látky po delší dobu, aniž by byly ovlivněny.
