Product Specs

Formulated to provide precise pH determinations, these buffer solutions which are standardized against N.I.S.T.-certified reference samples, are ideal for calibrating electrodes and pH meters. The buffers are color-coded to avoid error and accurate to within ±0.01 pH at 25°C (77°F). Each buffer contains a preservative/mold inhibitor and a shrink-sealed cap to prevent contamination and leakage. Temperature compensation charts are included with each buffer solution. The shelf life of the buffer solutions are 1 Year.

Rated 4 out of 5 by from pH buffers I bought pH buffers in 1 gallon jugs. Good value. Will buy again.

Rated 4 out of 5 by from Great Product DOESN'T COME IN BOTTLES Ph solution worked as advertised but was disappointed that the solution came in UN-resealable bags. I was under the impression they were in bottles.

Rated 5 out of 5 by from Solid Performance for the life of the bottle I use about 1 gallon over a nine-month period, and the expiration date on the bottle assures me that it's still accurate. This is a great price for a great product, which is why I will keep coming back to Omega.

If buffers are susceptible to contamination, how long are they good for after opening the container?

Asked by: Brent O
pH buffer solutions have 1 year shelf life. You should follow the expiration date on the bottle.
