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.

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.
