LeadCheck Kit

The LeadCheck Surface Sample Kit includes easy to use, self-contained sampling swabs with all materials required for the rapid screening of lead on surfaces and liquids.

1. Squeeze the swab to crush the front glass vial inside.

2. Squeeze the swab to crush the rear glass vial inside.

3. Shake the swab to mix the reagents.

4. While squeezing the swab, rub the surface to be tested for approximately 30 seconds. Within one minute, the swab will turn color if the contaminant is present.
