10% hydrogen peroxide concentration test strips can be used to assess 35% food grade peroxide (after dilution), only $26.95 for 100 strips.

The lowest level this strip can test for is 1% which is equivalent to 10,000ppm. The upper limit, 10%, is the same as 100,000ppm. At that concentration, the strip turns black immediately. The 0-400ppm hydrogen peroxide test strip is much more useful for hot tubs, pools and spas.

Details

These 1-10% test strips are used with concentrated hydrogen peroxide, aka "food grade". They change to only one color, black with concentration indicated by the speed of the color change. This timed response differs from the other peroxide strips which use color charts. These have a "lag time" before any color change is observed and a completion time where the final color change is observed. See table below.

Note: The bracked numbers in the two columns for 1, 2, 3% are for contact lens solutions & are different due to additives based on CIBA Geigy AOSEPT. These will vary with other similar products.

Concentration Lag Time Reaction Completion
10% (100,000ppm) Immediate Immediate
7% (70,000ppm) 2 seconds 3
5% (50,000ppm) 5 seconds 10
3% (30,000ppm) 10 seconds (20) 15 seconds (30)
2% (20,000ppm) 15 seconds (~40) 30 seconds (~60)
1% (10,000ppm) 30 seconds (~75) 60 seconds (~120)

Is your hydrogen peroxide stock solution 3%, 10%, 30%, 35%? No matter, use our hydrogen peroxide dilution calculator to take the quesswork out of making up a batch of 100, 200, 400 (or other) ppm hydrogen peroxide solution.

Or, use the strips 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 you made a mistake in the dilution). Try other dilutions to zero in on the actual strength, e.g. 1:6 should give you 5%; etc.
Specifications
  • These strips have a guaranteed minimum 2 year shelf life. The vials have a built in desiccant so if properly stoppered, strip shelf life can be 5 years or longer.
  • The number of strips per vial (100) is approximate.
  • Suitable for detection of hydroperoxides and ether peroxides. Polymeric peroxides, which can form in diethylether, are not detected. Organic peroxides, such as di-terc-butyl peroxide, di-cumyl peroxide or terc-butyl perbenzoate, either do not react or react with significantly reduced sensitivity.

Great product and service! Package arrived from North America to NZ within a week during the covid-19 shut down period. Will be ordering more in near future. Thank you!

I am quite happy with my purchase, the test strips do exactly what I need them to do. Price was quite fair and reasonable. Shipping was a bit slow but that is not your fault with the fiasco Covid-19 created. If I ever need a similar product I will most certainly look to Indigo Instruments to supply my need.

Great for a quick check of H2O2 percentage. Have used for years for in-process redundancy testing and shelf life testing of finished goods.
