Hydrogen Peroxide Concentration
Household peroxide is sold in brown bottles in drugstores and supermarkets. It contains 3 percent hydrogen peroxide. Hair bleach is about 6 to 10% hydrogen peroxide. "Food grade" hydrogen peroxide is 35%.
The most common concentration of hydrogen peroxide used around the home is 3%. It is sold in pharmacies & other retail outlets in brown bottles to protect it from rapid degradation caused by sunlight. It is typically used as is for a wound disinfectant, hair bleaching or diluted further for general sanitizing. Food grade, at 35%, is more concentrated and used to maintain the cleanliness of larger volumes of water such as hot tubs and pools. On a larger scale it is also used in water treatment.
These applications have different concentration requirements & test strips are used to confirm that the hydrogen peroxide is has been diluted correctly.
Our 4 ranges of
hydrogen peroxide test strips are:
All come with:
- easy to read color charts
- white backing for good contrast comparison
- stiff plastic; good for dipping into tubes

It will tell you how much undiluted peroxide to mix with water.
How to Test Hydrogen Peroxide
Hydrogen peroxide measurements are easy. Simply dip the indicator pad at the end of the strip into the water you want to test and compare to the color chart after

Note: This applies only to the 100, 400 & 5000ppm strips. The
10% hydrogen peroxide strip uses a timed reaction which corresponds to the different concentrations.
