Glass detector tubes are filled with an inert reagent carrier material (silica gel, aluminum oxide, or aluminum silicate) impregnated with an indicating reagent. Reagent produces a colorimetric indication in the presence of a particular gas, vapor, or aerosol. Concentrations can be read directly from the color change on the tube's printed scale. Tubes are hermetically sealed. Most have a two-year shelf life (when stored at room temperature). Available in packs of ten.
Extension of measuring range listed is possible for some detector tubes. Call Fisher Scientific™ at 1-800-772-6733 for more information.
