Fluorescent Polystyrene Spheres – Bright, Reliable, and Ready for Bioanalytics

At microParticles GmbH, we offer a broad selection of fluorescently labeled polystyrene spheres designed for high-precision applications in bioanalytics, diagnostics, imaging, and instrument calibration. These beads combine exceptional monodispersity (CV < 2%) with stable, high-intensity fluorescence, making them ideal for both research and routine use.

Key Features

High monodispersity for consistent flow and signal response.
Strong, photostable fluorescence for long-term imaging and detection.
Smooth, spherical morphology for predictable behavior in fluidic systems.
Available in a wide range of sizes.
Compatible with aqueous buffers and biological media.

Available Fluorescence Labels

Our fluorescent polystyrene spheres are available with a variety of excitation/emission spectra, including:

Color	Excitation [nm]	Emission [nm]
Color
Blue	UV (360) Laser 405	450(50)
Green	Laser 488 Laser 532	520(50)
Orange	Laser 488 Laser 532	520(50) 560(50)
Red	Laser 632	650(50)
