Description
VitraPOR® sintered glass pellets, Ø 4,0 mm, porosity 2, are porous microcarrier beads for adherently growing cell cultures. Made from pure, binder-free borosilicate glass 3.3, the pellets offer an inert and biocompatible structure suited to demanding cell-culture workflows. Defined pores support cell proliferation by limiting clump formation and promoting even distribution across the carrier surface. This 1 litre pack from manufacturer ROBU - Stereon is intended as carrier material (microcarrier) in research, biotechnology and preparatory work for clinical studies. The combination of controlled porosity grade 2 and a 4,0 mm diameter gives a reproducible geometry for adherent culture systems. Laboratories use VitraPOR® pellets where a chemically stable glass matrix and open pore architecture are required for reliable cell attachment and growth. The material meets professional expectations in industrial and academic settings that rely on consistent microcarrier performance for scale-up and experimental cell-culture applications.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about VitraPOR® Porous Glass Beads, Ø 4.0 mm, Por. 2
What is this article?
VitraPOR® Porous Glass Beads, Ø 4.0 mm, Por. 2 is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
