Hydrogen Peroxide Test Strips
What are Hydrogen Peroxide Test Strips?
Hydrogen peroxide test strips are an indicator to measure the residual concentration of hydrogen peroxide in a solution. They are stored in a plastic packaging container or vial to protect them from exposure to sunlight and moisture retaining shelf life, usually in a quantity of 100 strips.
The test strips consist of a stiff strip of plastic which is white to provide for good colour and contrast comparison. At the end of the strip is an indicator pad which reacts with hydrogen peroxide changing colour to signify an indication of detected peroxide concentration.
Provided with the test strip (usually on the container) is a colour chart which displays the indicative hydrogen peroxide concentration range the test strips detect and is used to compare to strips directly side by side.
Test strips give a quick and easy evaluation and are inexpensive when compared with electronic measuring equipment which also needs regular calibration.
How do hydrogen peroxide test strips work?
Hydrogen peroxide reacts with peroxidase (POD) and the organic redox indicator pad on the test strip which forms an oxidation compound that is blue coloured.
Depending on the concentration of the peroxide being exposed to the test strip indicator pad will change colour to display a result for comparison with the provided colour chart.
What ranges of test strip are available?
EndoSan test strips are available in 3 ranges which are suitable for detecting different peroxide ranges and lend themselves to different use cases. The ranges available are:
Can be used to detect hydrogen peroxide concentrations from 0ppm to a maximum 100ppm. The colour comparison scale displays colour differences indicating peroxide concentrations of 1ppm, 3ppm, 10ppm, 50ppm and 100ppm.
Can be used to detect hydrogen peroxide concentration from 0ppm to a maximum of 1000ppm. The colour comparison scale displays colour differences indicating peroxide concentrations of 100ppm, 200ppm, 400ppm, 600ppm, 800ppm and 1000ppm.
Can be used to detect hydrogen peroxide concentration from 0ppm to a maximum of 5000ppm. The colour comparison scale displays colour differences indicating peroxide concentrations of 500ppm, 1000ppm, 2500ppm and 5000ppm.
How do you use hydrogen peroxide test strips?
Test strips provide a quick and easy visual indicator of the levels of peroxide in any solution.
Test Strip Instructions for use:
- Take a fresh test strip from the container, without touching the indicator pad, and hold directly into the solution sample you with to test for two seconds.
- Remove the test strip from the solution shaking off any excess in the process.
- Allow the test strip indicator at least 30 seconds to develop a reading.
- Compared the test strip indicator pad with the colour range provided which should indicate a concentration level in the solution the test strip has detected.
- Always refer to any supplier provided instructions for your specific application to determine the peroxide level expected/required.
Please contact a member of the team for any instructions specific to your application and to ensure correct use of the appropriate range of test strips (low, high or extra high range).
The instructions above will cover most use cases where a residual peroxide level needs to be detected in a solution, however test strips can also be very useful in other applications.
How should test strips be stored?
To maximise test strip lifespan avoid exposing them to sunlight and moisture. Where possible refrigerate unopened containers. Once opened store containers in a cool (not refrigerated), dark, dry place. When removing test strips take only as many strips as are required and close the container immediately. Use all test strips before the expiration date marked on the container, strips can be disposed of as normal waste.
