Colored polymer particles is a new product line of microParticles GmbH. The intensely dyed monodisperse particles have been developed for use in applications like filter testing, flow tracing, medical diagnostics, and biotechnology. The particles, based on polystyrene and polystyrene copolymers, are produced with microParticles' own technology platform and come in a wide variety of sizes, dyes, and functionalities. Using specifically designed dyeing processes, intensely colored particles with complete dye retention are obtained. The new particles come as 5 wt.-% aqueous dispersions. With larger beads, also dry powders are available. The main product characteristics include:
  • Size range from 500 nm to 1000 µm.
  • Currently dark blue and dark red colors available
  • Narrow size distribution (CV < 3%).
  • High lot-to-lot reproducibility.
  • Spherical particles with smooth surface.
  • Surface functionalities (carboxyl, amino, and epoxy groups) available on request.
