Microspheres & Particles
Polysciences, Inc. is a world leader in the development of particle-based solutions for diagnostics, bioprocessing and instrument standardization. Our capabilities in life sciences, coupled with our expertise in specialty chemicals and electronics, allow us to address the unique requirements of advanced applications in medical devices, biosensors and nanotechnology.
Polysciences offers the most comprehensive range of particle solutions in the industry. We are your source for organic, inorganic, biodegradable, magnetic, fluorescent, dyed and specific antibody and general protein coated particles in diameters spanning the range of 40nm to 10mm.
Our line of BioMag® products include superparamagnetic particles and kits that offer superior performance in the isolation and purification of nucleic acids, antibodies and other proteins. Specific cell populations may be enriched or depleted using our range of BioMag® anti-CD marker particles.
Polysciences manufactures a comprehensive range of standards for analytical instruments such as cell analyzers, particle sizers and fluorescence microscopes. Our NIST Traceable Particle Size Standards feature low coefficients of variation, which make these particles suitable for use in a wide range of applications including instrument calibration, particulate testing, filter challenge and clean room testing. Our catalog also includes SureCount™ Particle Count Standards, ViaCheck™ Viability and Concentration Controls, and a broad range of fluorescent and antibody capture beads for flow cytometric and imaging applications.
