Hach Bromthymol Blue Indicator Solution is a 100 mL precision reagent that visually signals pH changes between 5.5 and 8.5 by shifting colors from yellow (acidic) to blue (alkaline), with a distinctive green at neutral pH 7. Packaged in a marked dropping bottle, it supports diverse applications including water treatment, aquaculture, and industrial quality control, making it an indispensable tool for accurate and efficient pH monitoring.

Great pH indicator and includes eyedropper.
Using as a pH indicator for a Borates test for a pool. 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.

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.

Not for School!
I ordered this for my science class...This is a much stronger chemical than what should be used in schools.
