QUANTUM Conductive Ultra Bins are permanently conductive and protect sensitive electronic components from electromagnetic interference. Carbon-filled, copolymer polypropylene material is unaffected by humidity and normal cleansers. Guaranteed surface resistivity is less than 10(5) ohms per square as tested under ASTM D257 while the electrostatic decay rate is tested to meet Mil-B-81075B at less than 0.1 seconds. Feature extra thick reinforced walls and wide hopper fronts. Stackable with an anti-slide stop that prevents bins from shifting forward. Order in carton quantities, priced each. Made in USA.
