  • NECi - Model NTK-TTLR & NTK-TTSR - Test Tube Format Nitrate Test Kits

    NECi - Model NTK-TTLR & NTK-TTSR - Test Tube Format Nitrate Test Kits

    Use this kit for quantitative nitrate analysis of essentially any aqueous sample, from wastewater to soil and plant extracts. This test tube format kit is to be used with your colorimeter or spectrophotometer capable of reading at 540nm± 20nm. NECi's recombinant Nitrate Reductase drives all Nitrate to Nitrite using NADH, which reacts with color reagents under acidic conditions to produce a visible color.

  • NECi - Model NTK-MPLR & NTK-MPSR - Microplate Format Nitrate Test Kits

    NECi - Model NTK-MPLR & NTK-MPSR - Microplate Format Nitrate Test Kits

    Use this kit for quantification of nitrate in essentially any aqueous sample.  Reactions occur on a 96-well microplate provided with the kit.  This test kit is based on the enzyme Nitrate Reductase (NaR), catalyzing the reduction of nitrate to nitrite using the natural electron donor NADH.  The nitrite reacts with color reagents under acidic conditions to produce a visible color. The concentration of nitrate in the original sample is...
