Gastec Soluble Ion Tubes

Gastec Soluble Ion tubes enable the measurement of dissolved substances in solution by simply immersing the tube into a solution vertically. Pointing upward, the solution will rise up through the tube due to capillary action and react with the reagent in the tube, giving a reading without the need for laboratory analysis. Applications include soil and water contamination.

Tubes are supplied in packs for 10 tests.
