Hydrogen Peroxide H2O2 Test Strips, 2-10%, High Level, 50-Pack

I purchase 7.0% for well water. Turned out the seller had sold me a bad batch. Seller is now replacing $400 worth of Hydrogen Peroxide thanks to these strips.

During the pandemic, hydrogen peroxide prices jumped, but when I got the 3% solution on my skin, my skin would turn white. If I poured it into the sink, fats would bubble. Now I get bottles for a buck that don't seem nearly as strong. These strips tell the story. See the video on the manufacturer's site to interpret the test patch. You stop your timer when the patch is solid black. I bought hydrogen peroxide with an NDC number so I can look up its composition. One label said 3%, but the NDC listing reads HYDROGEN PEROXIDE 2.65 mL/100mL. It also degrades over time. The strips work fine and the company tech support was very responsive.

Tested on new 15% solution and older one sitting around for a year. Worked to perfection. Easy to use.

I tested this in a new bottle of 3% food grade hydrogen peroxide and it was accurate. I will do some more testing before relying on it completely to dilute FG 35%.

Needed some peroxide for Covid 19 stuff at work. Had a titration test kit and compared to these and they worked fine. Tried at the lower end of the concentration not the higher end so don't know about 10% and higher.

Very quick shipping. Great price. Product works well. Just what I needed for work.

We have a peroxide system to remove sulfur from our well water, and these strips do a perfect job of testing the strength for consistency. The folks in customer service are exceptionally helpful and thorough. Thanks for a great experience!

Seems to work fine. The strips exhibited reasonable accuracy and precision when testing with a 7.5% peroxide solution.
