Si 00857 silicate/silicic acid reagent test is a photometric kit for determining silicate and silicic acid concentrations in the measuring range of 0,5 - 500 mg/l Si. It uses the silicomolybdenum blue method and corresponds to DIN 38405 D21 as well as US 4500-Si D/E. The package provides reagents for 100 tests and works with sample volumes of 4 ml or 0,5 ml in 20 mm cuvettes. Designed for PhotoLab® and pHotoFlex® photometers, the test supports efficient routine analysis of water samples. This complete 1 pkg kit from manufacturer WTW - a Xylem brand includes a batch certificate to document quality. Laboratories apply the reagent test for silicate monitoring in environmental water, process streams and quality-control workflows where reliable Si quantification is required. The ready-to-use reagents simplify preparation and measurement steps while maintaining consistency across multiple determinations on the compatible instruments.
