High-quality, color-fixed pH test strips feature a long handle that prevents fingers from coming into contact with the sample, allowing for optimal workplace safety. To prevent bleeding, the pH indicator is chemically bound to the cellulose fiber, protecting the sample against contamination and enabling measurements even in weakly buffered or strongly alkaline solutions. Four different color blocks for each pH value (0-14) ensure highly precise pH determination and make the application rapid and reliable. Flat box contains 100 test strips, 6 x 85 mm.
