Details This listing is for a nickel spot test kit to detect nickel in any metal. I am an industrial formulation chemist by trade and have sourced the highest quality nickel spot testing kit. Unfortunately, there is no current cure for a nickel allergy. Avoidance is the only action, the nickel spot test kit detects nickel so you can avoid it. The kit tests for nickel in any metal. Testing of jewelry, watches, necklaces, rings, buttons, eye glasses, silverware and belt buckles can be done within 30 seconds. One kit is sufficient for 100+ tests. The nickel spot test kit detects nickel down to 10ppm (parts per million). The sensitivity threshold of most nickel allergy's is above 11ppm. Directions for use 1. Take solution A and add a few drops to a cotton bud. 2. Take solution B and add a few drops to the same cotton bud. 3. Rub the cotton bud onto the test item. 4. A positive test for nickel will result in a pink colour appearing on the cotton bud Packaging The nickel spot test kit will be packaged in 2 x 10ml dropper HDPE bottles and sent in a strong jiffy bag. Health and Safety I hold an MSDS (Material Safety Data Sheet) for this material and it is available on request as a pdf file which I will send to you. All my products come with the appropriate labels indicating correct handling and safety. Happy Bidding.
