Macherey Nagel 91338 QUANTOFIX Nitrite/pH

Macherey Nagel 91338 QUANTOFIX Nitrite/pH

The Macherey Nagel 91338 QUANTOFIX Nitrite/pH designed for simultaneous determination of nitrite (NO₂⁻) and pH in water samples. Therefore, they are highly suitable for applications that require quick dual-parameter analysis, such as water quality monitoring, aquaculture, and environmental testing. Moreover, these strips combine the Griess reaction for nitrite detection with a mixed indicator system for pH measurement, ensuring reliable and consistent results.

In addition, the strips provide two distinct color changes: white to red-violet for nitrite and yellow-orange to violet-red for pH. As a result, users can easily interpret both parameters at the same time using the provided color scales. Furthermore, the strips require no additional reagents, making the testing process simple, fast, and efficient.

Key Features

• Dual-Parameter Measurement
  First, the strips measure both nitrite and pH simultaneously. Therefore, they improve efficiency by reducing the need for separate tests.
• Fast and Easy Testing
  Moreover, the strips enable rapid analysis without complex preparation. Thus, they are ideal for routine and on-site applications.
• Clear Colorimetric Results
  In addition, distinct color changes for each parameter ensure easy and reliable interpretation of results.
• Wide Measurement Range
  Furthermore, the test covers nitrite up to 80 mg/L and pH from 6.0 to 9.6. Therefore, it is suitable for various water quality conditions.
• No Additional Reagents Required
  Additionally, the strips are ready to use directly. As a result, testing becomes faster and more convenient.
• Reliable Detection Methods
  Moreover, the use of the Griess reaction and mixed indicator system ensures consistent and dependable results.
• 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. Consequently, it is suitable for long-term use.
