355-425µm

Our crosslinked Polystyrene Beads are larger than Polybeads®, yet smaller than Polyballs. We offer a full size range of polystyrene beads and can offer particles of intermediate sizes on a custom basis.

500-600µm

Highly uniform 1/4" polystyrene spheres with an etched surface. The surface roughness of 100-120µm promotes better adherence of proteins, etc. for biological applications.

Density = ~1.05 g/cc
