So if I wanted to test an old bottle of 35% I could dilute with 3+ parts water and then test right?

That is a great question. Our Time Sensitive Peroxide test strip can be used to confirm the strength of 35% food grade peroxide by mixing 1 part 35% peroxide solution with 2.5 parts water to yield a concentration of 10%. If the color change is not immediate, then the initial concentration was not 35% (or a mistake was made in the dilution). Try other dilutions to zero in on the actual strength, e.g. 1:6 should give you 5%; etc. Please let us know if you have any further questions! -Scott

Are these clibrations based on H2O2 % by volume or weight?

on portion/percentage of H2O2 in the liquid which is H2O2 + H2O; for instance, a 3 % H2O2 makes the stick turns purple in a longer time than say a 12% portion; each stick has a tip of 3mili-meter by 3 mili-meter which will turn eventually purple after a dip

These expire two years after the date of manufacture, therefore, if you order from "Bartovation" you will be able to use them for ATLEAST 18-24 months after the date of purchase. I can not give a specific exp date as it varies from batch to batch.

What is the exp date, the bottle shows 2014?

That is an example of what the bottle will look like, and is not a picture of the bottle you will be receiving. This specific P/N expires two years after the date of manufacture, therefore, if you order from "Bartovation" you will be able to use them for ATLEAST 18-24 months after the date of purchase. I can not give a specific exp date as it varies from batch to batch.
