pH Buffer Solution
All of the following Reference Standard Buffer solutions are compared against and certified traceable to National Institute of Standards and Technology (NIST) Standard Reference Materials. Exact reference materials used are shown on the product labels. Accurate to ±0.01 pH of indicated value at 25°C. Standard buffer solution liquid is colour coded for instant identification of pH value in either the bottle or container used for test.
For most routine pH measurements, a two-point standardization of a pH meter should be used:
- pH 4 and 7 buffers can be used for pH measurement of samples of pH 7 or below
- pH 7 and 10 buffers can be used for pH measurement of samples of pH 7 or higher
Other combinations of pH buffers may also be used, depending on the capability of the pH meter being used. For increased accuracy, buffers with pH values closer to that of the sample being measured can be used.

Great for summer pool time
Size: 2.1 Fl Oz (Pack of 1)
Gave it 5 stars because it really does its job. I used this sunscreen on my face during the summer when I was going to the pool a lot. It goes on white at first, but once you rub it in well the white cast pretty much disappears. Doesn’t make my face super greasy and protected my skin really well, no burns, no weird tan lines, nothing, as long as I reapplied it like the instructions say. The smell is light and not annoying. The bottle is small and easy to keep in a bag. Overall, a good product that actually works.
