Litmus Paper Test Strips

Buy red or blue litmus paper for foolproof acid or base testing experiments: red litmus turns blue for alkaline; blue litmus turns red tests for acid. Litmus paper is the easiest and most foolproof way of determing whether something is acid or base. Either the strip changes color or it doesn't. It's that simple.

Buy litmus paper in 25 strip pads or 100 strip vials for fast, foolproof acid/base tests: red litmus tests for alkaline; blue litmus tests for acid.
  • fast response time-just seconds
  • easy to use for acid: blue strips turn red
  • easy to use for base: red strips turn blue
  • 100 strips/vial; minimum 2 year shelf life
  • 25 strips/pad; store in a sealed jar for longer life
