SOLAS™ Porous Silica Particles

SOLAS is a proprietary process for the world’s first monodense, monodisperse fully porous silica particle for applications in chromatography, drug delivery, diagnostics, energy etc. These particles represent the cutting edge in silica technology and are unique in that they combine particle monodispersivity, and monodensity along with and a wide range of pore sizes through Glantreo’s Controlled & Stable Porosity (CSP) process. These innovative particles offer seamless bonding and functionalisation capabilities. Additionally, the SOLAS  particles represent a media that is easier to pack with a reduced failure rate in packing.

Monodense SOLAS porous silica particle

End applications include:

❖Supports for metal and enzyme catalysts


❖Drug Delivery and controlled drug release


❖Water and air filtration


❖Sensing Devices due to high customisability


❖Insulation Materials due to low thermal conductivity
