NECi - Model PTK-TTSR-100 - Test Tube Format Phosphate Test Kit: Standard Range, 100 Samples
This kit is supplied complete with all necessary reagents except for HPLC water. Use this kit for quantitative phosphate analysis of essentially any aqueous sample, from wastewater to soil and plant extracts. Simply extract solid samples using HPLC water before analysis. This test tube format kit is to be used with your UV capable spectrophotometer capable of reading absorbance at 360nm.
Standard Range Assay (5 ppm - 20 ppm Phosphate)
Analyze 100 Samples With This Kit
When reaction is complete, the purine product yields an increase in absorbance at 360 nm in equal molar ratio to the inorganic phosphate in the reaction mixture. Using the equation of the linear regression line fitted to the set of phosphate standards, the phosphate concentration a sample can easily be determined.
In addition to this kit, you will need a graduated cylinder, variable pipetters, a test tube vortex-type mixer, spectrophotometer capable of measuring 340 nm with UV compatible cuvettes, clean and phosphate-free 13 x 100mm test tubes, a timer, HPLC water, and ice.
