Overview
- Notes
- G9 Trace Metals solution for J Medium (UTEX). Provides essential micronutrients for freshwater algae culture. Preparation: Add components in the listed order to approximately 900 mL deionized water while stirring. Make up to a final volume of 1 L. Storage: Refrigerator temperature; no exact temperature is established by this source. The source also prints a Final Concentration column and a stock-solution footnote. Those annotations are retained as a source interpretation issue, not asserted here as independently verified stock molarities. The structured values use the explicit g/L Amount column. No receiving-medium dose or replacement molarity is inferred.
