Description

  • This is a time-sensitive reaction requiring from 0 to 20 seconds
  • Designed for testing food grade hydrogen peroxide (or other oxidizing agents)
  • Very High Level Peroxide Test Strips measure Peroxide solutions from 2% to 10%

The Time Sensitive Peroxide test strip, 2-10%, is a time sensitive strip for testing highly concentrated hydrogen peroxide solutions (“food grade”). The concentration of the solution being tested is determined by the length of time it takes the color to change to black.

Instructions:

  1. Dip the Time Sensitive Peroxide test strip into the solution for 1-2 seconds. Do not swirl.
  2. Remove strip, and hold level. Do not shake off excess water.
  3. Evaluate the color of the test pad beginning at 0 seconds.

Results:

The white test pad will turn purple, then black. After removing the test strip from the solution you must time how long it takes for the strip to become black.

Note: If the solution is for contact lenses, the solution (3%) will remain white for 20 seconds, then turn black.

How to measure the concentration of 35% Food Grade Hydrogen Peroxide: 

The Time Sensitive Peroxide test strip can also 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.

Sample Reactions

The numbers in brackets for 1, 2, 3 percent are for contact lens solutions. The 1 and 2 percent values are based on dilutions of the 3% product, and thus are only estimates. Tests are based on CIBA Geigy AOSEPT and may differ for other similar products.

Frequently Asked Questions (FAQ)

How do peroxide test strips work?

The test pad is treated with a formula consisting of buffers, surfactants, a red-ox indicator, and an enzyme. The enzyme makes the strip very sensitive to peroxide. The presence of peroxide causes the red-ox to develop color. The intensity of the color developed is proportional to the amount of peroxide present.

Does this strip work with Accelerated Hydrogen Peroxide?

The peroxide test strips were developed to work with solutions prepared from concentrated solutions of hydrogen peroxide. Some formulations of hydrogen peroxide contain surfactants to create an “accelerated” peroxide solution. These “accelerated” solutions may work with the test strips but almost always require a custom color chart to be developed.

Do these test strips detect organic peroxides?

Yes, our low level peroxide strips can measure organic peroxides. Two specific examples are Peracetic Acid (PAA) and Peroxyoctanoic Acid (POOA), both of which give positive responses using these strips.

That being said, while the color scheme appears similar, the color chart supplied with this strip has not been calibrated to PAA, POOA, or any other organic peroxide. It is calibrated to hydrogen peroxide. Also keep in mind that organic peroxides (like PAA) are often a mixture that includes hydrogen peroxide.

Can I test 35% food grade peroxide with this strip?

The Time Sensitive Peroxide test strip can also 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.
