Product Overview

Colored Carboxylated Particles  (Red/Blue)

Our colored polystyrene latex particles are made by incorporating organic color dye into our uniform white PS latex particles. These red and blue beads are used in applications when color visualization is important for detection and are widely used in rapid (lateral flow) tests. These are also available with carboxyl functionality. Color intensity can be customized to suit your specific needs. Please contact us for details.

PSB300NM and PSB400NM are widely used in rapid tests.
