Litmus PH Test Strips 160 Strips, Professional Universal pH.1-14 Test Paper with Test Pipette Droppers, for Teaching, Student, Chemistry Experiment, Saliva Urine Water Soil & Diet pH Monitoring

I was about to leave a bad review and ask for my money back when I read another review that made me think about testing other things. I bought these strips to test the PH for my Orchid fertilizer to make sure it was in the right range. The test for that in my tap water both came out yellow looking pretty much like the original paper but after I tested orange juice, Windex , rice vinegar, and a few other things the papers actually worked. If your paper turns yellow rest assured that it’s in the range indicated by the color indication strips.

So I first used this on my tap water which is pretty neutral (dark yellowish color on ph strip) It looked as if nothing changed but when i looked closer the color of the paper is fairly close to that of a neutral ph level then under the light I noticed a slight green tinge. I didnt know if these worked properly but after testing with different solutions of baking soda and vinegar I can confirm it works great. Hard to tell just how accurate your solution is, obviously with the colors being subject to interpretation i.e. how one actually sees colors or the type of light that its under. But for general purposes this is cost effective and works great. Thanks

purchased these for making apple cider vinegar. I found them easy to use and read.

The test strips arrived as represented and promptly. I especially appreciated the pipettes. I would purchase these again. All around, an A+ experience.

Purchased when we realized the science teachers forgot and they students had a lab the next day. Received them same day and saved the day!

I tested this on water, saliva, and Kombucha just to make sure it changed colors since some reviews said it didn't. In each instance the color did change, but after letting is sit for a minute, the colors were close to the same or changed as it ran through the paper. The color scale that comes with the paper has some colors so close, it was hard to tell which color was correct. I will not repurchase. I got it at a cheap price so I will not complain much. The pipettes were nice to add but they are so small, I thought they had shipped without them. I found them in the plastic with the paper. Now I have no idea where they went.

The Litmus PH Test Strips set of 320 strips seemed like a good deal, but unfortunately, the results have been quite inconsistent. The strips frequently provided varying readings for the same solution, making it challenging to trust the accuracy of the pH measurements. This inconsistency poses a significant issue, especially for professional or precise use. Additionally, the color indicators are not always easy to distinguish between certain pH levels, leading to confusion. While the quantity is ample, the unreliability and lack of clear, consistent results make these strips fall short in terms of accuracy and dependability." Paper not thick at all and the quality is the worst that I've seen

Has everything you need to test liquids including a plastic dropper.
