Hanna HI38061-100 Phosphate ascorbic acid method

Hanna HI38061-100 Phosphate Reagents – Ascorbic Acid Method (100 Tests)

The Hanna HI38061-100 Phosphate ascorbic acid method is a replacement reagent set formulated for precise phosphate (PO₄³⁻) measurement across a wide concentration range. Designed for use with the HI38061 Chemical Test Kit, this set allows users to conduct up to 100 tests using the ascorbic acid colorimetric method. Whether testing environmental water, drinking water, or agricultural runoff, this kit supports reliable, easy-to-interpret results.

Key Features

• Covers a Wide Detection Range: This reagent set enables phosphate measurement across three concentration ranges: 0.00–1.00 mg/L, 0.0–5.0 mg/L, and 0–50 mg/L.

• Proven Ascorbic Acid Method: In this method, phosphate reacts with ammonium molybdate and potassium antimonyl tartrate to form a phosphomolybdate complex, which is then reduced by ascorbic acid. The result is a blue-colored complex whose intensity correlates with the phosphate concentration.

• Checker Disc for Visual Accuracy: Users compare the color development with a reference disc for accurate, side-by-side readings—no digital instrumentation required.

• Pre-Measured for Convenience: Hanna prepares each reagent in exact quantities, ensuring quick setup and eliminating measurement errors.

• High-Purity Chemicals: The reagents contain only laboratory-grade compounds to ensure consistent and reproducible results.

• Traceability Built In: Every packet includes a lot number and expiration date, supporting good laboratory practice and documentation standards.
