Among the grades of products that we offer are colored microspheres.

The microspheres, extremely uniform, are dyed internally (their surface properties are unchanged), insuring maximum color brilliance and preventing dye leaching in water or aqueous buffers. 

The main applications for Estapor® Dyed Microspheres are the following :  

• Membrane-based technologies
• Latex Agglutination tests "LAT"
• Latex Hemagglutination tests "LHT"
• Immuno-chromatographic Assays
• BioSensors and BioChips

We offer more than 100 dyed microspheres (red, blue, green, black, yellow…). This well known effect is called Rainbow Effect.

The possibility to incorporate colored dye into our uniform microspheres greatly enhances their interest and usability in some tests and opens up new frontiers for applications in the diagnostics, life sciences, biotechnology, electronics or environment fields.
