Great volume for my purposes as it will likely last for hundreds of tests, and the included eyedropper is a must have, so much easier to use than from other manufacturers that don't include an eyedropper. Not really sure what the other reviewer is talking about, since the concentration doesn't seem outrageously strong to me. I use .5mL in a 50mL sample that starts at a pH between 7.2-7.8. Review: Borate Test for Pool - I'm using this to run a borate test for my pool. Much more accurate that using the stupid test strips. Check Trouble Free Pool for more information. ## Features - Widely used as a mid-range pH indicator in the lab, it changes color from yellow in acidic conditions (pH less than 7) to blue in alkaline ones (pH greater than 7), making it useful for monitoring pH changes in titrations and other chemical reactions.
