Yes, the tester will work on clay soil .
While holding the capsule above the sample tube, squeeze or roll the thinner half gently to break the "seal" or friction bond holding the two halves together. Then start twisting the two halves in different directions while gently pulling them apart.

Was not sold in store where I live. I ordered online and had it within 5 days at store for pick up.
Hello Alex. I believe the pH kit will work in lawns. I read drill out 3 " of soil using one inch auger (cut whole in a flat board,or plastic sheet (tb top), to catch the dirt), then take next 1 inch of soil in multiple places for samples to check pH (the 3-4" section) . dry partially and crush in plastic bag,discarding organic matter . Make Sure crushing is fine, as sample is very small to be tested, and you want a good representative sample of all the yard spots you tested added together. My soil test took a bit to settle to check water color against the provided color scale next to it .
