Dyed Microparticles

A number of dyed microparticles based on polystrene are also available. Dyes include dark blue and dark red. Other properties are the same as for the non-dyed particles:

  • Density: 1.05 g/cm3
  • Refractive Index: 1.59
  • High monodispersity and uniform spherical shape
  • Hydrophobic surface
  • Non-specific adsorption of proteins
  • Low temperature resistance up to 100°C
  • Soluble in organic solvents (dependent on the degree of cross-linking)
  • Swellable in organic solvents
  • Coefficient of Variation (C.V. value) of <3 % for research grade particles and for particle size standards available
