Description
Equivalent to VWR # EM1.09540.0001
The strips feature covalently bound indicator dyes so that they will not bleed even in strong alkaline solutions. Strips can be immersed in samples for extended periods so that even weakly buffered solutions can be accurately tested without contaminating the sample. The universal strip tests the full 0–14 pH range with a sensitivity of 1 pH unit. Intermediate-range indicators provide a sensitivity of 0.3–0.5 pH units and narrow range strips provide a sensitivity of 0.2–0.3 pH units.
