Microspheres, Spheres, Nanospheres - Worldwide
Paramagnetic microspheres have the ability to increase in magnetization with an applied magnetic field and loose their magnetism when the field is removed. No residual magnetization is observed and that provides the end use very practical advantages, including ease of separation and suitability for automation.
Cospheric's highly spherical paramagnetic black polyethylene microspheres offer the flow of standard microspheres, with the ability to be separated from other materials for reuse and cleanup. These highly opaque microspheres are homogeneous polyethylene and are often used in microscopy for high contrast cross sections.
