Lead Check Swabs
Detect Lead on any surface....Instantly!
Only $7.75 each plus GST and postage.
Description LeadCheck® Swabs are non-hazardous and provide a rapid, sensitive and specific test for leachable lead on any surface. When lead is detected, LeadCheck® Swabs and/or the surface being tested turns pink or red on contact, depending on the concentration of lead present. In the vast majority of test situations results are obtained in less than 30 seconds. When detecting low levels of lead, or lead chromate containing pigments, results may take longer to develop. Each kit contains test confirmation cards to verify individual test results. Available in single units or in bulk packs of 12 - 48 per pack.
Since their introduction in 1992, LeadCheck® Swabs have been used to detect lead under a wide variety of field test conditions. Recognized by industry professionals for superior accuracy and sensitivity, LeadCheck Swabs have outperformed other screening methods in every USA government evaluation conducted over the past 15 years.

Each LeadCheck® Swab contains a lead reactive dye and a buffer solution containing ingredients designed to maximize the sensitivity and specificity of the reaction. None of the materials used in LeadCheck® Swabs are hazardous. The chemistry is based on known principles. Under the conditions of the reaction in LeadCheck® Swabs, the reactive dye is highly specific for lead forming a pink or red colored ion association compound. The color of the complex increases almost linearly with increasing metal ion concentration when the reactive reagent concentration is kept constant as it is in LeadCheck® Swabs. In the presence of certain chemicals additional test precautions are required.
- Sulfates: Most commonly found in plaster, Sulfates can block the colour development on the test surface and LeadCheck® Swab tip. Cleaning the surface to remove plaster dust is usually all that is required. PB-08 Plaster, Stucco
- Tin: Most commonly encountered when testing solder, high levels of tin can turn the Swab Tip purple. When lead is present the LeadCheck® Swabs tip will turn pink before turning purple. For a full discussion click the following link: PB-01 Solder.
- Red Paint: Red paint pigments can come off of test surfaces - coating the Swab. PB-12 Red Paint, PB-07 Red Lead.
- Delayed colour reaction: Occurs when very low levels of lead are present PB-22 Low Level Testing (0.06%), or when lead does not easily leach from the surface PB-05 Chromate Paint. If pink is seen anywhere on the LeadCheck® Swab tip or where the tip contacted the surface the test is positive for lead
