Precious Metal Test Kit
This two-solution test kit includes everything you need for testing when refining gold. The Precious Metal Test Solution will detect even infinitesimal amounts of dissolved precious metals (gold, silver and platinum group) in solution (sensitive down to 4 parts of precious metal for every million parts of solution). The Ammonia Test Solution will test for dissolved impurities clinging to your refined gold mud (also sensitive to 4 parts per million). This kit includes: test solutions, spot plate and sampling pipette. Everything is integrated into a machined PVC base. Both bottles contain enough solution for hundreds of tests.
