QUANTOFIX® Nitrite test strips: Quick and easy determination of nitrite. Features: • These test strips are for the rapid and reliable determination of Nitrite in solutions. • The easy dip-and-read-procedure provides a reliable result within 1 minute. • Nitrite is a contamination indicator and therefore an important parameter that is tested regularly in a wide variety of settings. • To determine the nitrite concentration, very often nitrite test strips are used. • Nitrite is an undesired byproduct in cooling lubricants. • It allows the formation of carcinogenic compounds. • Cooling lubricants are therefore regularly tested with nitrite test strips. • Additionally, nitrite is an important parameter for aquacultures and fish farming. • Nitrite is formed in the decomposition of organic material. • High levels can lead to the disruption of filtration units. • Moreover, long-term exposure can be harmful to fish. • In natural and drinking water Nitrite can lead to infant mortality and dead aquatic life. • The EPA primary drinking water standard is 1 mg/l. Nitrite test strips are ideal to use for water control due to the quick and easy procedure. • Nitrite test strips are also important in quality controls of food, e.g. meats and spinach. • Excessive amounts of nitrite can potentially be harmful to consumers, especially to infants. • QUANTOFIX® nitrite test strips are the ideal choice to check nitrite levels quickly and easily. Specifictions: • Presentation: Tube of 100 test strips. • Color reaction: white → red-violet. • Gradation: 0 · 1 · 5 · 10 · 20 · 40 · 80 mg/l NO2– (Nitrite).
