Protect your electronic components from typical electromagnetic interference (EMI), electrostatic or induced fields with these molded, carbonfilled, copolymer polypropylene bins. Surface resistivity is less than 105 Ohms-per square. Easy access to stored items with hopper front bin and label holder provides fast identification. The conductive material provides a barrier which these fields cannot penetrate and prevents the build up of electrostatic charge. Bins are permanently conductive and are unaffected by washing with normal cleaners. Be sure all units are properly grounded according to your use. Color is Black.
