Ingredients: 1,1' dimethyl 4,4' dichlorodipyridine. Decomposes at about 300 ° C; vapor pressure is negligible at room temperature, soluble in water; slightly soluble in lower alcohols; insoluble in hydrocarbons, TC purity >95%, salts are stable in neutral and acidic media, but Oxidation under alkaline conditions, clay and organic matter can quickly and strongly absorb the drug; absorption capacity changes greatly, 20-300Drmg / kg, mainly depends on the content of clay / organic matter, absorption requires 12N (H / 2), (no/4) After several hours of digestion, the paraquat drug is corrosive to ordinary metals; when diluted, it has no obvious harm to the spray device, and this product cannot be mixed with anionic surfactant.
Centrifuge tubes are used in laboratory centrifuges, machines that spin samples in order to separate solids out of liquid chemical solutions. The centrifuge tubes can be made of glass or plastic, and resemble miniature test tubes with tapered tips. They are mainly used in series test like the centrifuge of nucleic acid
