Measure free fluoride ions in aqueous solutions quickly, simply, accurately, and economically with Thermo Scientific™ Orion™ Fluoride Electrodes.
9609BNWP is a combination electrode with  a Sure-Flow™ junction that allows easy cleaning. When conventional electrode junctions clog, the Sure-Flow junction can be opened and flushed clean simply by pressing the cap. 9409SC requires a separate electrode cable with a screw cap connector.
Fluoride Half-Cell Electrode 9409BN and 9409SC are to be used with the Orion 900100 sure flow single Junction reference electrode. 

The measurement of fluoride in drinking water using an ion selective electrode is an approved ASTM method: ASTM D 1179 A separate reference electrode is unnecessary with the combination fluoride electrode, making it convenient to use with small sample volumes.

  • Free-flowing Sure-Flow junction assures stable, drift-free potentials.
  • When conventional electrode junctions clog, the Sure-Flow junction can be opened and flushed clean simply by pressing the cap.
  • Fluoride Half-Cell Electrode used in conjunction with the Orion 900100 Single Junction Reference electrode offers the benefits of the Sure-Flow junction design:
    • Calibration standards catalog number: 940906 — 0.1 M NaF; 940907 — 100ppm F-; 040906 — 1ppm F- with TISAB II; 040907 — 2ppm F- with TISAB II; 940908 — 10 ppm F- with TISAB II
    • Required ISA catalog number: 940909 — TISAB II; 940911 — TISAB III
