Staticide 7250 Microfiber Foam Swabs are exceptional quality swabs for the critical cleaning of ESD static-sensitive surfaces. Constructed of medical-grade foam wrapped in microfiber knit, this swab is highly effective in removing and holding liquid or dry contaminants in volume. The rigid ESD handle has a dissipative resistance and will not generate a charge. The inner foam pad adds increased liquid holding capacity and cushion while microfiber enhances pick-up and can withstand abrasion. These characteristics make it ideal to use with solvents such as acetone, ethanol, isopropyl, and methanol and for applying or removing lubricants in hard-to-reach areas.
