Ascorbic Acid (Vitamin C) Test Strips, 50-Strip Pack

These ascorbic acid test strips measure Vitamin C concentration in water-based solutions and water extracts using a redox indicator that shifts from blue toward colorless as ascorbic acid reacts with the strip. The measurement range spans 0-0.1% (1000 ppm), with a detection limit of 0.005% (50 ppm) and color chart reference points at 0, 0.01, 0.02, 0.05, and 0.1%. To use a strip, dip it into the prepared sample and compare the resulting test pad response with the provided color chart. Each vial contains 50 strips, suited to comparing ascorbic acid levels across water-based solutions and prepared water extracts in educational and laboratory investigations.
