Column packing

These small pellets are made of pure, binderless sintered glass, and represent a completely new substrate for use in bioreactors. The open-pored structure of approx. 40...100 µm permits microorganisms to accumulate in the cavities between the sintered glass particles. This ensures that even deeply-embedded cells are supplied with the surrounding medium. Moreover, the material's high purity and its smooth surface provide optimum conditions for high cell growth. Application areas Trickle bed reactors in sewage treatment Substrate for microorganisms and cells in bioreactors Special features Pure sintered borosilicate glass 3.3 Pore size about 40...100 µm Pellet diameter 4 mm Large surface area Optimum flow characteristics High surface charge (Zeta potential) Top-class biocompatibility Enhanced cell growth, because there is no cell agglomeration due to confinement in microcapsules. This REM image shows the open structure and the smooth surface as a result of the sintering process....
