As a substrate
When used in solid-phase biotechnological synthesis processes, the interconnecting microstructure and functionalization possibilities of Controlled Pore Glass (CPG) powder enables the reversible binding of enzymes and oligonucleotides, for example. While conventional polymer solutions cannot fulfill increasing requirements regarding porosity, CPG can be produced with tightly controlled pore sizes and pore size distribution, enabling increasingly complex synthesis processes.
As a carrier for liquids
The high surface area of porous glass powder enables the bonding of large amounts of liquids or other active substances that can be released on demand. Application examples include e-cigarettes or vaporizers, as well as many other applications that require a porous microstructure.
As a desiccant
A high specific surface area and silica content of 90% or more enables the binding of large amounts of residual moisture. Application areas for high-performance desiccants made from porous glass include sensitive optical devices used in harsh environments and safety-critical applications that rely on and benefit from highly efficient, miniaturized, and reusable desiccants. For example, the protection of moisture-sensitive electronics in medical devices or defense night vision goggles from the damaging effects of residual moisture/condensation.Learn more
As a filter, separator, or membrane
Because of its small pore size distribution, high reliability, and the ability to form porous glasses as monoliths and platelets, (micro-) filtration, material separation and membrane technology are further use cases. Specific application examples include thin layer and gas chromatography, hyper filtration of water, ultra filtration in downstream processes, and usage as membrane reactors.
