1kg - 1000g Activated Aluminum oxide - beads 3.2mm

We use this material to achieve a hydrocarbon-free vacuum and in our glovebox to remove H2O. It can be regenerated at temperatures from 150 - 200 deg. C.

highly porous, spherical shaped Aluminum oxide with a high specific surface und high mechanical stability; it does not decompose in water.


In comparison with Silicagel, Activated Aluminum oxid has a higher adsorption capacity for water at higher temperatures.

Typical uses:
- cleaning of gases and liquids, incl. organic liquids (removal of traces of metals)
- Claus-Catalyst in sub- dewpoint Applications
- Bed support in air drying applications (PSA, TSA)
