Our freeze-drying technique reduces the aggregation usually associated with dried beads. Dry material allows for the buffer of choice to be easily added.

Polybead® Microspheres are monodisperse polystyrene microspheres available in sizes from 50nm to 90μm. Our experienced chemists control the synthesis to provide precise monodisperse particle size distributions. These particles contain a slight anionic charge from sulfate ester.

Additional sizes can be ordered on a custom basis. Request Quote
