Hanna HI3833-050 Phosphate ascorbic acid method

Hanna HI3833-050 Phosphate Reagent Kit – Ascorbic Acid Method (50 Tests)

The Hanna HI3833-050 Phosphate ascorbic acid method reagent kit enables precise and reliable measurement of phosphate (PO₄³⁻) levels in water samples using the ascorbic acid colorimetric method. Designed for use with compatible Hanna test kits, this refill pack is ideal for monitoring phosphate in environmental studies, aquaculture, agriculture, and wastewater treatment.

Features

• Pre-Measured, High-Quality Reagents
  Each reagent in the HI3833-050 kit is pre-measured to ensure consistency and eliminate guesswork. As a result, users can quickly obtain accurate results without complex preparation steps.

• Based on the Ascorbic Acid Method
  This method follows a well-established chemical reaction: ammonium molybdate and potassium antimonyl tartrate react with orthophosphate in an acidic medium to form a phosphomolybdate complex. Subsequently, ascorbic acid reduces the complex, producing a blue-colored solution.

• Visual Color Comparison for Fast Interpretation
  The intensity of the blue color correlates directly with phosphate concentration—the deeper the blue, the higher the level. The kit includes a color comparator cube for quick, side-by-side visual analysis.

• Optimized for Low to Moderate Phosphate Levels
  With a measurable range of 0 to 5.0 mg/L (ppm) of PO₄³⁻, this kit is well-suited for routine monitoring in natural waters, aquariums, and controlled environments.

• Convenient for Field or Laboratory Use
  The compact and portable format allows for easy integration into both lab benches and field testing kits. Furthermore, the reagents are suitable for users of all experience levels.

Applications

• Aquaculture and Aquariums
  Monitoring phosphate levels helps prevent algae overgrowth and maintain a healthy aquatic environment. Therefore, this kit is a key tool for fish farms and aquarium professionals.

• Environmental Water Monitoring
  Researchers and field technicians use the kit to assess nutrient pollution in rivers, lakes, and coastal waters. Consequently, it supports efforts to control eutrophication and preserve water quality.

• Agricultural Runoff Analysis
  In agricultural zones, excess phosphate from fertilizers can contaminate water systems. This kit assists in identifying and managing runoff impacts.

• Wastewater Treatment
  Operators regularly monitor phosphate levels to ensure proper treatment and regulatory compliance. In addition, it helps optimize chemical dosing during the treatment process.
