Copper, Free & Total, Single Parameter Test Kit, Model: CU-6, Color-disc/Bicinchoninate, Hydrosulfite reduction. Copper may exist in natural waters and effluents as a soluble salt or as suspended solids. A small amount is essential for plants and animals, and concentrations exceeding 0.1 mg/L are useful for controlling algae and plankton growth. Quantities ranging from 0.02 to 0.1 mg/L are toxic for some fish, so its used for treating fish disease requires careful monitoring. Our Long-path Cube Kit (P/N 2193800), sensitive to 0.05 mg/L free copper, is ideal for this use. USEPA-accepted for waste water and potable water. Approved by some states for potable water under specific conditions. Check with your regulatory agency.
