Quantity :

To test for residues simply wet the strip's testing pad with water (deionized or distilled if available) & press against the surfaces of fruits, vegetables, cutting boards & utensils, etc. for at least 10 seconds & then compare against the color chart.

Note (1): Levels less than "10" ppm are impossible to determine but current rules for organic certification call for "0" ppm. This is next to impossible & unrealistic since water alone causes a reading of 10ppm. Read more in our blog on what 10ppm really means when measured on a knife or other surface.

Note (2): If vial is properly stoppered, strips have a minimum 2 year shelf life. If you promptly stopper the vial after removing a strip, you should expect at least another 1 year if not longer.

Note (3): The number of strips per pack or vial is approximate.
