Description

For determination of high range silica by the silicomolybdate method (Hach method 8185), and low range silica by the heteropoly blue method (Hach method 8186).
Pack of 100 Powder Pillows.

Hach Citric Acid Reagent Powder Pillows are precision-engineered reagents designed for accurate silica analysis across multiple measurement ranges. This comprehensive pack of 100 powder pillows supports both high-range silica determination via the silicomolybdate method (Hach method 8185) and low-range silica quantification through the heteropoly blue method (Hach method 8186). Each 10 mL pillow delivers consistent, pre-measured citric acid reagent formulation, eliminating manual preparation steps and reducing measurement variability. Ideal for water quality laboratories, industrial process monitoring, and environmental testing applications, these reagents ensure reliable results in silica concentration analysis. The convenient pillow format provides extended shelf stability, simplified storage, and rapid deployment in high
