Micro Essential Lab 9800 Plastic pH Test Strips, 0.0 - 14.0 pH 1 Vial of 100 strips

These are very accurate compared to a cheaper vial of 100 from a diffferent brand. Too bad it only is really use once, toss. Usually i used to extend them by ripping one into many pieces (which i can do with the other 100-pack vial i got. These are more accurate and clear, glad I bought it :).

These do not work. I put a different strip in multiple substances all of which I knew to be varied in ph, and the color did not change for any of them. If there is something missing, there were no instructions as to what else was required. Either poor quality, or poor communication by the company.

I bought these a few years ago to test for ketosis while following a low-carb diet and they worked.I saw a commercial today that said that reverse osmosis makes water acidic. I recently switched to reverse osmosis water thinking I was helping my health, but now I see I'm making my body more acidic. :(After see the commercial I dug out these strips to test my reverse osmosis water against my tap water. And they worked.My tap water tested at around 7pH and my reverse osmosis water tested around 5 pH. :(After testing the water I decided I would order a new container since the ones I have expired at the end of last month.That's when I read the comments about people having trouble with them working in water.After reading those comments I did another test and I added baking soda to tap water, which as someone else said should have made the water very alkaline. And it did. The tap water with baking soda came out around 9 pH.So, I'm happy with these strips and am ordering again.To people who said the strip didn't change color, my take is that whatever you were testing was at a 5 or 6 pH, which is the base color of these strips. Also, be sure you are putting the yellowish end in whatever it is you are testing.I think the color chart is good for generalizing your results (very acid, acid, neutral, alkaline, very alkaline). But yes, it can be difficult to distinguish between, say, an 8 pH and a 9pH. But at that point you can easily tell that the solution is alkaline, versus acid, neutral or very alkaline. But if you need an extremely accurate reading, you should probably have the work done at a lab.

Hard to read.

I was hoping for more. These just did not work as well as I had hoped. Everything just looked like it was in the same pH range even when I used controls.

They work fast and are easy to read. I got them for work

The media could not be loaded. I check my pee's pH several times a day few times a month to find out how my diet changes the pH of my pee. Here is a picture shows a pH 8 after I had 16 ounce of Almond milk with spinach, hemp & flax oil. I see the colors changing on the strips it depends what I eat & drink. Seems accurate. I also love that that the wide range from 0.0-14.0 compare to other strips that shows 5.0-8.0I recommend this Hydrion Plastic pH Indicator strips.

They work perfectly. Easy breezy! I use for checking the pH of homemades and the these work like a charm. The price is reasonable. And I will purchase again if price stays reasonable.
