Product Details

Pre-weighed amounts of buffer powders at three pH values-pH 4.0, 7.0 and 10.0. A correctly calibrated pH meter will check at all three points. These buffer powders are stable and have an excellent shelf life. Dissolve the powder in distilled or deionized water and use. The buffer preservative provided acts as a mold inhibitor and also colors each solution as follows: pH 4.0-red-orange; pH 7.0-green; pH 10.0-blue. Each capsule makes 100 mL of solution. Each vial contains ten capsules or enough to make, in total, one liter of buffer solution for each of three pH ranges.
