#91311 QUANTOFIX® Nitrite |
$30.45/Tube of 100 strips |
||
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. QUANTOFIX® nitrite test strips are the ideal choice to check nitrite levels quickly and easily. |

#91322 QUANTOFIX® Nitrite 3000 |
$30.65/Tube of 100 strips |
||
This test strip is for the rapid and reliable determination of Nitrate and Nitrite in solutions. The easy dip-and-read-procedure provides a reliable result within 1 minute. Nitrite is an undesired byproduct in cooling lubricants. It allows the formation of carcinogenic compounds. Cooling lubricants are therefore regularly tested for Nitrite. 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. |
