The company manufactures and sells chemical indicators, biological indicators, sterilization packaging, cleaning verification products, laryngoscope products, microscope slides, and other medical consumables. Its portfolio is centered on supporting sterile processing departments and regulated manufacturing environments rather than developing therapeutic drugs.

The business appears to be a long-standing, commercially operating healthcare manufacturer rather than a clinical-stage biotech company.
