Macherey Nagel 91320 QUANTOFIX Phosphate

Macherey Nagel 91320 QUANTOFIX Phosphate

The Macherey Nagel 91320 QUANTOFIX Phosphate Test Strips are semi-quantitative strips designed for rapid determination of orthophosphate (PO₄³⁻) in water samples. Therefore, they are highly suitable for environmental monitoring, water treatment, agriculture, and laboratory applications where accurate phosphate control is essential. Moreover, these strips utilize the phosphomolybdenum blue method, ensuring reliable and consistent detection of phosphate levels.

In addition, the strips provide a clear color change from white to blue-green, allowing easy visual interpretation. As a result, users can quickly estimate phosphate concentration using the provided color scale. Furthermore, the strips are compatible with QUANTOFIX Relax reflectometers, enabling more precise and objective instrumental readings when required.

Key Features

• Fast and Practical Testing
  First, the strips enable rapid phosphate detection without complex preparation. Therefore, they are ideal for routine and on-site applications.
• Clear Colorimetric Results
  Moreover, the color transition from white to blue-green ensures easy and reliable interpretation of results.
• Reflectometer Compatibility
  In addition, the strips can be evaluated using QUANTOFIX Relax reflectometers. As a result, users can obtain accurate and consistent measurements.
• Wide Measurement Range
  Furthermore, the test covers concentrations from 0 to 100 mg/L. Thus, it is suitable for detecting low to high phosphate levels.
• Reliable Phosphomolybdenum Blue Method
  Additionally, the chemical method ensures consistent and dependable detection of orthophosphate.
• Enhanced Accuracy with Reagents
