Rated 5 out of 5 by from Excellent for education, convenient, easy to use. I have been using these, pH 2, 4, 6, 7, 8, 10 and 12, for over 30 years. (I supplement them with 0.1 M HCl [pH 1] and 0.1 M NaOH [pH 14]) I use them for teaching acids, bases, and pH to students, classes, and outreach activities. Depending on the size of the group, I only use about 10 mL of the buffer solutions for up to 100 participants. I can safely take them anywhere in the world, keeping them in labeled, sealed containers. It takes about 24 hours for the capsules to dissolve in distilled or deionized water. The buffer solutions are stable for years if properly stored.
