    Measure Bioavailable Phosphate On-Site

    These kits require the use of NECi’s Handheld Photometer, results are not colorimetric

    Quick and Reliable Results, Easy to Use, Environmentally Benign

    This reagent refill test kit will measure 0 ppm - 20 ppm Phosphate in soil and sediment samples to be analyzed with our handheld photometer.  If you do not yet have a handheld photometer, please view our introductory photometer package complete with a test kit for 10 samples. This method is based on the Methods X article published in April 2015, Determination of phosphate in soil extracts in the field: A green chemistry enzymatic method.  This method features small sample volumes, an enzymatic reaction, and green analytical chemistry.  


    Phosphate Measurement in 5 Easy Steps:

    1. Collect Soil Samples, add to extraction tube and mix
    2. Add drop of extraction mix to enzymatic reaction cuvette
    3. Enzymes react with phosphate in sample
    4. Read measurement at 360 nm using NECi's handheld photometer
    5. View, track, store, and share results using any Android mobile device!
