 New! Aerogel Nanogel Granules (Frozen Smoke)  Art. Nr. 005061  
New! Aerogel Nanogel Granules (Frozen Smoke)
magnify Click to zoom!

Aerogel Nanogel NEW!

You get one vial with about 10ml Aerogel granules

It is the lightest and lowest-density solid known to exist, and holds 15 entries in the Guinness Book of World  Records, including best insulator and lowest density solid.
Aerogel is composed of 99.8% air and is chemically similar to ordinary glass.

It is nicknamed frozen smoke, solid smoke or blue smoke due to its semi-transparent nature and the way light scatters in the material; however, it feels like expanded polystyrene (Styrofoam) to the touch.

Silica aerogel strongly absorbs infrared radiation. It allows the construction of materials that let light into buildings but trap heat for solar heating. It has extremely low thermal conductivity (0.03 W·m/m2·K down to 0.004 W·m/m2·K, which gives it remarkable insulative properties. Its melting point is 1,473 K (1,200 °C or 2,192 °F). Silica aerogel can protect the human hand from the heat of a blowtorch at point blank range.

Activated Aluminum Oxide - spherical  3.2mm
magnify Click to zoom!

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)
