## Description

Litmus pH Test Strips, Universal Application (pH 1-14), 20 Packs of 100 Strips: desertcart.com: Industrial & Scientific

Review: Worked great for CP soap and a great price. - I used the test strips for CP soap. The color change was very quick and I was able to match the color to the chart with no problem. I also tested my pool water to compare the results to my pool test strips. According to my pool test strips the ph is about 6.2 or 6.8. The result of the new litmus test strips was about a 6 (give or take), because in this range there is little or no change in color to the test strip. While these may be too large a range to measure the pool ph, they are perfect for my cp soap. Since I was able to perform a comparison test And receive similar results, I feel my reading for my soap is fairly accurate. Overall, I am very pleased with my purchase. Oh, and I forgot to mention delivery was really fast.
Review: They work. - Convenient package, BUT they should make the front cover a little bit shorter so that it doesn't overlap the staple and can self-close like a matchbook. At least on the books I received, the front cover is the same length as as the back, with a significant overlap of the staple, so unless they're re-creased they won't close flat. However, the strips work adequately. Results reasonably matched expected values for pineapple juice, tap water, white vinegar, 10% sodium bicarbonate solution, and to verify (along with mass comparison) that I'd successfully calcined my sodium bicarbonate into sodium carbonate (again with a 10% solution). Did not have so much success with testing pH of a sourdough starter I was trying to make, but that's pretty thick (so checking with litmus paper may not be very accurate) and the starter didn't work out and was tossed out, so it might've been plenty accurate: the litmus paper showed it to be somewhat acidic but not as acidic as it should be to kill off bad bacteria; as well, after several weeks, it did not seem to get the right bacterial strains to stop smelling nasty from bad bacteria, so it was tossed out. Have not tried again yet.

### ⭐⭐⭐⭐ Good Price for Test Strips with General Values, but not Precise Values
*by E***H on April 1, 2017*

My test strips were delivered on March 11, 2017. This is a good product to obtain a general, but not precise PH value of saliva and urine. I test my PH in the morning and at night before bed. In general, a PH value of 4-6 is acidic; 7 is neutral; and 8 is alkaline. The body is functioning in a healthy range when the PH value is between 6.0 - 6.5 in the morning and between 6.5 and 7 in the evening. My daily PH values are in the range of 6-8. However, I am disappointed that these strips do not have a color variant for 6.5 and 7.5. Also, the golden color for the 6 value is similar to the original color of the test strip. I look at the test strip in different light to compare color changes to the chart. I also use test strips from the Stanaway Roll and the Hydrion type strips. The LabRat strips and the Stanaway Roll strips have similar general PH values. The Hydrion strips have 3 values in the 5 range; 4 in the 6 range; 3 in the 7 range; and 2 in the 8 range. I use the LabRat strips more due to the economical price.
