These packs are designed for users ordering nitrate reductase enzyme reagent packs greater than 1 unit of enzyme/vial to bring final concentration to 1 unit/ml.
This optimized nitrate reductase storage buffer is always recommended for reconstituting NECi's nitrate reductase for usage and storage purposes. These diluent bulbs may be stored at room temperture, but we recommend storing at 4°C.
When ordering nitrate reductase in 2, 3, or 5 units per vial, use 1 enzyme diluent bulb per unit to acheive 1 unit enzyme per ml of solution. This is the recommended concentration for most nitrate assays.
One- to two-minutes of spinning soil samples gives more accurate results and can save hours of waiting for samples to settle before testing. This may be necessary for certain soil types, especially clay and silt.
NECi has developed a smartphone app for Apple and Android devices to make nitrate determination easier, greener, and more accurate, all in the palm of your hands. There's no need for guessing the color of your sample according to the 4 color panel included in our instructions. Simply go to Google Play and search "nitrate color slider" to find the free app for your smartphone.
