Frequently Asked Questions
Approximately how many tests per roll is there?
There is approximately 100 tests per roll depending on the length of paper you tear off each time. For instance, if you used a strip of paper at 25mm or 1 inch, you'll get close to 180 tests!
Can I use my pH Litmus Test Paper 6.5 - 13.0 to measure the pH of urine & saliva?
You can but as the body is designed to be in an alkaline state (pH 7.0) there is a more accurate option to be found in the pH Litmus Test Strip Roll 5.5 - 8.0 or the pH Plastic Strips 5.5 - 8.0. These two measuring products have pH measurement intervals in the 0.2 making them a better option for urine & saliva.
Can I use my pH Litmus Test Paper to measure the pH of water?
No. The reagent used in the pH Litmus Paper is designed for buffered solutions only.
What is a buffered solution?
A buffered solution is a solution with adequate dissolved solids to resist pH changes. For example, urine and saliva are considered buffered in their natural state. However, rain water, tap water etc. are considered to be dilute, weakly buffered solutions.
