LabChem LC109721 Ammonium Chloride Salt, ACS, 500 g Weight
- It is both odorless and non-toxic, and possesses an unlimited shelf life..
- It precipitates in heavy, shiny, flake form, making rinsing and decanting much easier and faster, avoiding inadvertent losses of gold during rinsing that are so common when using virtually every other precipitant..
- Quadratic precipitates gold of at least 99.95%+ purity..
- Comes with complete instructions for precipitating pure gold and a link to free and complete instructions for the entire gold refining process..
- Can also be used with sodium metabisulfite. When used in conjunction with smb, it reacts with the tiny smb precipitated gold particles, causing them to clump together forming large heavy gold particles..
