Strip pH test paper pH: 4.0-10.0 100 sheets JT10631 1 box (100 sheets)

Unlike typical filter paper test strips, they consist of four or three cellulose discs, each impregnated with a different indicator, individually pressed onto a polypropylene strip. Each of the four or three different color indicators changes color depending on the pH value of the sample solution, so by comparing/collating with the included color scale (color change table), you can make a more accurate judgment than with conventional pH test paper. Unlike filter paper test strips, capillary action prevents your fingertips from coming into contact with harmful sample solutions. 100 test papers, 5mm wide x 83mm long (in a plastic case).
