Project Description

Our dyed polystyrene microspheres have vivid colors. The organic color dye is incorporated into the interior of polystyrene latex microspheres, which makes the beads less prone to color bleaching.

EPRUI guarantees stable batches and has a variety of specifications to choose from. Colored microspheres are commonly used in lateral chromatographic experiments and latex agglutination tests.These red colorful beads are also used in applications when color visualization is important for detection and are widely used in rapid (lateral flow) tests.

Our dyed polystyrene microspheres are filled with the best oil soluble dyes with high contrast ratio. The colors in our palette represent our color standards. These are also available with carboxyl functionality. Non-functionalized and carboxylated microspheres support physical adsorption and covalent binding or other different methods.
