Macherey Nagel 91306 QUANTOFIX Sulfite

Macherey Nagel 91306 QUANTOFIX Sulfite

The Macherey Nagel 91306 QUANTOFIX Sulfite Test Strips are semi-quantitative strips designed for rapid determination of sulfite (SO₃²⁻) in water and process solutions. Therefore, they are highly suitable for food processing, beverage production, water treatment, and industrial applications where sulfite levels must be monitored accurately. Moreover, these strips utilize the Nitroprusside/Zn-hexacyanoferrate method, ensuring reliable and consistent detection of sulfite ions.

In addition, the strips provide a clear color change from white to salmon, allowing easy visual interpretation. As a result, users can quickly estimate sulfite 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
  Moreover, the strips enable rapid detection without complex procedures. Thus, they are ideal for routine and on-site applications.
• Clear Colorimetric Results
  In addition, the color transition from white to salmon ensures easy and reliable interpretation of results.
• Reflectometer Compatibility
  Furthermore, the strips can be evaluated using QUANTOFIX Relax reflectometers. As a result, users can obtain accurate and consistent measurements.
• Reliable Detection Method
  Additionally, the Nitroprusside/Zn-hexacyanoferrate method ensures dependable and repeatable results.
• 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.
