EMD Millipore t.h.e.® Desiccant
EMD Millipore t.h.e.® Desiccant can be used to dry air, carbon dioxide, natural gas, non-polar hydrocarbons, and organic solvents. This silica gel desiccant has a high adsorptive capacity and can adsorb up to 35.8% of its weight in water. Desiccant packs easily into drying columns and desiccators. Desiccant features a spherical shape which enhances moisture adsorption in drying tubes. t.h.e.® Desiccant maintains physical integrity, even when fully hydrated to eliminate messy slurries. Silica gel desiccant is inert except with water which can introduce impurities. The indicating type silica gel desiccant includes a cobaltous chloride indicator. Indicating silica gel desiccants are blue when dry and pink when hydrated. The indicating types of silica gel desiccant can be regenerated easily by re-heating. Non-indicating form contains silica gel.
To regenerate for re-use t.h.e® Desiccant can be spread on a metal baking sheet. Heat at 120°C (248°F) for one to two hours and the desiccant is ready for re-use.
