Product details
Nitrite is a highly toxic substance that can oxidize ferrous ions in hemoglobin into ferric ions, causing it to lose its ability to bind oxygen and hinder the transport of oxygen in the body, leading to acute poisoning in the human body. It can also combine with organic amines to generate carcinogenic nitrosamines, which pose a threat to human health.
To eliminate the tedious operation of preparing reagents and testing processes for users, and improve detection efficiency, based on the diazo coupling method (GB/T8538-2008), a
Low range nitrite prefabricated tube reagentIt is easy and fast to operate, with low testing costs, and can meet the requirements of batch, rapid, and accurate determination of various water quality.
Low range nitrite prefabricated tube reagentBased on diazo coupling spectrophotometry (GB/T8538-2008): Nitrite in water is diazotized with p-aminobenzamide, and then coupled with N - (1-naphthyl) - ethylenediamine to generate a purple red azo dye. The color depth is proportional to the nitrite content in water.
Product Features
1. Pre made reagents can be measured directly without the need for users to redistribute them;
2. Imported glass tubing with good reproducibility to ensure testing accuracy;
3. Improve the prefabricated pipe cover, tightly match with the pipe thread, eliminate the phenomenon of crooked head, and improve the sealing performance;
4. Can be directly applied to mainstream brand machines without the need to reconstruct curves;
5. The testing process is simple and convenient, reducing time costs and improving work efficiency;
6. Reduce the opportunity to come into contact with hazardous chemicals and ensure the personal safety of operators;
7. The reagent usage is small, resulting in less waste liquid.
