Spherotech

Spherotech is a privately held life science tools company that manufactures and supplies uniform polymer microspheres, latex microbeads, and related micro- and nanoparticles for biomedical, diagnostic, and research applications. Its product portfolio includes fluorescent, magnetic, coated, functionalized, silica, and calibration particles used in flow cytometry, cell isolation, immunoassays, molecular diagnostics, and instrument quality control. The company appears to operate primarily as a commercial products and enabling-tools business rather than a therapeutic drug developer. Spherotech also offers custom particle development and surface-functionalization capabilities for assay development and other laboratory workflows. The company is based in Lake Forest, Illinois and serves a global customer base.
