CoralPor®
SCHOTT offers two high-quality porous glass types, with the right pore size for every purpose. CoralPor® Nano-Porous glass starts from approximately 4 nm pore size, while CoralPor® Macro-Porous glass is available from ~ 1 μm up to any desired value.
CoralPor® Nano-Porous
The interconnected coral-like structure of CoralPor® Nano-Porous glass is created during a special production process in which the borosilicate mother glass is subjected to meticulously controlled thermal and chemical treatment. This creates open porosity that can be tailored to meet even the most demanding customer specifications.
YOUR ADVANTAGES
- Excellent absorption and separation capabilities due to very large internal surface area and narrow pore size distribution
- Enabling stable results and efficiency due to ultra-robust, long-lasting material. Properties include:
- Low coefficient of thermal expansion
- High thermal stability
- High chemical resistance against a large variety of different media - Available as a powder or monoliths in various shapes and sizes
APPLICATIONS
Examples include:
- As a substrate in synthesis processes e.g. for enzymes
- Thin layer chromatography
- Ultra- and microfiltration
CoralPor® Macro-Porous
CoralPor® Macro-Porous glasses have a comparatively coarse pore structure. They are usually manufactured from alkali silicate or borosilicate mother glasses, but are not limited to such compositions. The open porous structure can be tailored over a wide range of size and volume.
YOUR ADVANTAGES
- Excellent thermal stability depending on base glass
- Completely inorganic
- Customized surface treatment upon request
- CoralPor® Macro-Porous Glasses can be produced:
-With an average pore size between 1–500 μm
-A pore volume of up to 80%
-As sintered monoliths in various shapes and sizes
-As porous microspheres / powders
APPLICATIONS
Examples include:
- As a substrate in synthesis prcesses e.g. for bioreactors
- Microfiltration
- Carrier for liquids or active substances, such as evaporation units in e-cigarettes or vaporizers
