The Excelta 213C-N 4.75" Long, Medium Clean Room Safe Brush has a 0.312" diameter handle with 0.375" long and 0.375" wide bristles. Made with stainless steel handles and new Statigo9 fiber bristles. Made in USA.
Statigo9 is a static-dissipative acetal (ESD safe with a surface resistivity of 106) that is as durable as nylon, thick enough to perform mechanical work, does not shed or slough, and is clean room compatible. The bristles are mechanically clamped into the handle for maximum fiber retention without the use of adhesives that could contaminate the work area.
