Profile: Corpuscular Inc. provides research and development microspheres & nanospheres, custom micro particles, standard & custom surface chemistries to the world's research communities with speed & flexibility. We offer the largest selection of monodisperse inorganic polymer and magnetic microspheres & nanospheres. The size range of our micro particles is from few nanometers to about one hundred microns. These truly spherical and uniform particles are prepared to satisfy the most demanding applications requiring uniform & monosized micro beads with plain & functionalized surfaces. Our microspheres & nanospheres have plain, amino, carboxyl, avidin, biotin, streptavidin, antibody finished surfaces and are suitable for applications in immunological research, separation of cells, nucleic acids & proteins. Each product is designed and manufactured to meet/exceed the highest quality standards. We specialize in the production of microspheres and nanospheres used predominantly in research & development projects. Our NIST traceable standard microspheres and nanospheres are exceptionally monodisperse particles made of silica. These are provided in an easy-to-dispense format. These are used in biological applications to determine the size of viruses, bacteria and cellular components, ceramics, powders, clays, pigments, abrasives, polishing compounds & soils.
