Stiff-Line surgical instrument cleaning brushes have been designed with more rigid medical grade nylon bristles that allow for aggressive cleaning. Also incorporated in the design are thicker, twisted stainless steel shafts that resist bending. The brushes feature Spectrum’s Antimicrobial bristles, which resist bacterial growth, last longer and offer superior infection control properties. Spectrum’s blue Stiff-Line™ brushes are easily identifiable and available in 5-mm, 10-mm, and 15-mm diameters. The brushes come three per package.
