The Xylem PhotoLab Test Kit PO4 offers precise photometric measurement of phosphate (PO4) in various water samples. This reagent-based kit provides 100 tests, requiring an 8 mL sample volume using 10 mm cuvettes. It is compatible with PhotoLab S12, PhotoLab Spectral, spectroFlex, and pHotoFlex photometers, covering phosphate ranges up to 100.0 mg/L PO4-P and 307.0 mg/L PO4. Suitable for wastewater, drinking, surface, and fertilizer water analysis, this kit also supports seawater testing, though it is not applicable for total phosphorus in seawater.
Product Features
- 100 reagent tests for reliable phosphate quantification
- Sample volume of 8 mL with 10 mm cuvettes
- Compatible with PhotoLab S12, PhotoLab Spectral, spectroFlex, and pHotoFlex photometers
- Wide measurement range: 1.0–100.0 mg/L PO4-P; 3.0–307.0 mg/L PO4
- Designed for diverse water types including seawater
- Easy to use with standardized photometric methods
Note: The vanadate-molybdate (VM) method can be affected by humic substances. For total phosphorus determination, models 14848, 00616, 00798, and 14842 require Crack Set 10 or 10-C with empty round cuvettes and heating (100 °C or 120 °C for 1 hour). For P6/25 use CombiCheck 10; for P7/20 use CombiCheck 20 or CombiCheck 80.
