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
