Agglutination Test Slide


Welcome to Magsphere Inc.

Magsphere Inc. is pleased to offer high-quality in house manufacturing of monodispersed polystyrene latex particles, also known as uniform latex particles, latex nanoparticles, and monosized latex particles(microparticles) to the medical and scientific communities.

For nearly 3 decades, our products have been used in both research and commercial diagnostic applications. By working directly with our customers, we are proud to provide high quality monosized latex nanospheres and microspheres and the technical support necessary for the development of successful particle-based products. Our products can be used as NIST traceable particle size standards, FACS (Fluorescence-activated cell sorting) standards, as well as in slide agglutination tests (latex agglutination tests such as CRP and HCG), lateral-flow rapid tests and particle enhanced turbidimetric and nephelometric immunoassays. Our precision microbeads are also used as LCD spacers to control cell gap.

We can conduct a custom synthesis in 50 to 100mL batches of special latex particle, latex microspheres, magnetic particles, fluorescent microspheres, or any polymer particles that are not listed as standard products. To meet your full-scale production, we manufacture reproducible latex in 5 liters to 150 liter resin reactors. We can collaborate with your research team to scale up your custom batch size of microspheres or nanospheres according to your needs.
