Chemtronics 38540ESD, Coventry ESD Static Control Swabs, Case of 2,500 - 500 Swabs/Bag, 5 Bags/Case=Case of 2,500 Knit poly - 2.7 inch (6.9 cm) handle, 0.12 inch (3.1 mm) head Engineered to eliminate damage from static electricity. The handles of these swabs will dissipate 99% of a 5,000 volt (5 KV) charge in less than 2.0 seconds. The static dissipative plastic alloy used to make the handles is inherently static dissipative. It contains no additives, coatings or surfactants so it functions at any level of humidity and it is very resistant to solvents — even acetone. FEATURES & BENEFITS Excellent solvent resistance Surface resistivity of 1010 ohms/sq. Low ionic, nonvolatile residue, and particulate contamination No humidity dependency No Amines, no silicones, no static dissipative coatings No Tribo-charge generated Handles will dissipate 99% of (5 kV) charge in 0.5 seconds APPLICATIONS Use in any static sensitive application Technical Data Sheet
