Macherey Nagel 91311 QUANTOFIX Nitrite

Macherey Nagel 91311 QUANTOFIX Nitrite

The Macherey Nagel 91311 QUANTOFIX Nitrite designed for rapid determination of nitrite (NO₂⁻) in water samples. Therefore, they are highly suitable for environmental monitoring, water treatment, aquaculture, and laboratory screening where fast and reliable nitrite analysis is required. Moreover, these strips utilize the well-established Griess reaction, ensuring accurate and consistent detection of nitrite levels.

In addition, the strips provide a clear color change from white to red-violet, allowing easy visual interpretation. As a result, users can quickly estimate nitrite 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 Efficient Testing
  First, the strips enable rapid nitrite detection without complex preparation. Therefore, they are ideal for on-site and routine applications.
• Clear Colorimetric Results
  Moreover, the color transition from white to red-violet 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 80 mg/L. Thus, it is suitable for detecting low to high nitrite levels.
• Reliable Griess Reaction Method
  Additionally, the chemical method ensures consistent and dependable detection of nitrite ions.
• No Additional Reagents Required
  Moreover, the strips are ready to use without extra chemicals. Consequently, testing becomes faster and more convenient.
• Compact and Portable Design
  In addition, the lightweight packaging makes it easy to carry for field testing and routine inspections.
• Long Shelf Life
  Finally, the product offers a shelf life of up to 2.5 years when stored properly. Therefore, it is suitable for long-term use.
