MACHEREY-NAGEL Test strips fort he dairy industry
Reliability made in Germany
Trust the test paper experts with over 50 years' experience — competent and dedicated! Because quality and availability are important to us, we continue to rely on our German production facilitiy – from paper manufacturing to finished test strips. This makes us the perfect partner for the dairy industry in the following areas:
Safety in seconds – Precise nitrate monitoring
High levels of nitrate in animal feed can cause it to accumulate in milk, where it is converted into nitrite. Nitrite is particularly toxic to infants. To ensure food and baby food are safe, nitrate and nitrite levels must be strictly monitored. Our QUANTOFIX test strips make monitoring fast, easy and reliable. Find all the necessary information on analysing dairy products in our applications section.
Excellent precision: QUANTOFIX Nitrate 250
Thanks to their extra-large test area, our QUANTOFIX Nitrate 250 test strips deliver highly accurate results, as our comparative study shows. The measurement inaccuracy is less than 5%!
Interested in testing for nitrite as well? QUANTOFIX Nitrite 25 is the perfect complement.
For details on the precision of QUANTOFIX Nitrate 250, please refer to the comparative study. See for yourself!
The 2-in-1 solution: QUANTOFIX Nitrate 100
With two test fields, you can measure both nitrate and nitrite simultaneously using just one QUANTOFIX Nitrate 100 test strip. This saves you both time and money!
Objective and convenient – Our QUANTOFIX Relax
Automation eliminates subjective color perception and provides a quantitative analysis of the test strips with digital documentation. Take your analytics to the next level!
Super easy to clean
The device is designed to prevent direct contact between the sample and the measurement optics. A contaminated test strip holder is easy to clean—even in the dishwasher!
Maximum flexibility
All of our test strips can be evaluated using the printed color scale on each label - for a maximum of flexibility!
No chance for germs – Reliable disinfection monitoring
Hydrogen peroxide, peracetic acid, or chlorine
Disinfection is essential for producing delicious and long-lasting dairy products. Our QUANTOFIX product line offers a wide range of test strips for various disinfectants. Find the right strip for your application!
Reliable residue control
Disinfectants are not beneficial to human health. Check the safety of your dairy products with QUANTOFIX test strips—even in very low concentration ranges.
Focus on quality – pH, pasteurization, minerals
Our classic: pH-Fix
The pH is an important indicator of milk freshness. pH-Fix 6.0 – 7.7 optimally covers the relevant range. pH-Fix technology prevents dyes from leaching into the dairy sample.
Is it hot enough?
Use Phosphatesmo MI and Peroxtemo MI to determine the levels of alkaline phosphatase and lactoperoxidase for precise monitoring of the heating process.
Essential minerals
Determine the mineral content of dairy products quickly and easily with QUANTOFIX Calcium and QUANTOFIX Potassium!
Butter quality
Test the water-butter separation in accordance with DIN 10311 using our perfectly sized WATOR water test papers.
Applications for the analysis of dairy products
Dairy products are usually thick and opaque, which often causes photometric methods to fail. That's why test strips are a better option!
With a slight adjustment to the procedure, samples can be analysed despite their high fat and protein content. Read more about each application in the relevant section.
