Additional Technical Information

Merck-US:/Lab/red_bullet.jpg With the indicating form, the desiccant color change begins at about 13% adsorption.
Merck-US:/Lab/red_bullet.jpg t.h.e. Desiccant adsorbs 5% of its weight in 16 hours
Merck-US:/Lab/red_bullet.jpg Indicating drying agents turn pink in color when hydrated (moist). In its dry (anhydrous) state the cobaltous chloride indicator is blue in color. Upon regeneration, the gel changes from pink back to blue and can be used again.
Merck-US:/Lab/red_bullet.jpg Regenerate by heating at 120°C for 1-2 hours
