Ascorbic Acid Vitamin C Food Test Strips, 0.01 to 0.1% [Vial of 50 Strips]

Did what it should do and lets you know the Ascorbic Acid level after treating your pool for heavy staining. This is important because Ascorbic Acid Kills Chlorine so no use in using chlorine if Ascorbic Acid is present but you still need to use Algicide to keep algae from forming until you can use chlorine again.

It worked great for testing Vitamin C levels for my son's school STEM project. Please note that citric acid levels affect the coloring of the test strip. You will need to use the chart shown in the product photos if you are testing anything with citric acid.

This was used for a science fair project and was easy to use.

My son used used it for school and said it was easy to use and seemed to work well. He did say that he had to go to the website for additional color charting. He would recommend purchasing it.

This was used for my daughter’s science project it really didn’t work well on what we tested.

Good tool for experiment but need more detailed information in reading and analyzing results

We bought this one was for the kids’ project. They need the ph test strip for different fruits. It is very good and packed very well, but a little bit expensive. I’m not sure how long we can keep these strips.
