pH ACCURACY
Now you can establish the accuracy of your pH meter or other potentiometric apparatus with three new products . . . B U F F A R solutions made by Mallinckrodt. Standardized against National Bureau of Standards reference samples, B U F F A R solutions are accurate within ±0.01 pH units (at 25° C) of the values appearing on the labels. A handy conversion table right on the label allows you to interpolate for other temperatures. B U F F A R pH 7.00 is also available as a concentrated solution—for additional economy. A companion product—Potassium Chloride Saturated Solution AR®—is available for replenishment of calomel reference electrodes.
