Silica Gel Orange Indicator

High-efficiency adsorption bead silica gel impregnated with an organic indicator. Developed as a safe-rated alternative to highly toxic blue cobalt impregnated gels. Beads turn from orange-yellow to green as they adsorb moisture. Regenerate beads to their original dry state once they’ve become saturated heating to 100-120ºC. Free of foreign impurities such as chlorides, sulphates and other organic matter. Most economically supplied in 25 kg air tight containers or may be broken down into smaller bagged volumes.
