* During work in cleanrooms, contamination by dust is a major concern. That is why the Cleanroom edding 8011 marker contains no metal parts or labels. * This edding marker is water-resistant and resistant to dry wipe, with markings that can be erased on smooth surfaces with isopropanol, making it THE solution for people working in dust-free environments such as laboratories, the medical sector, or the nanotechnology industry. * The cleanroom marker ink is water and abrasion-resistant and can be erased from almost all films with isopropyl alcohol. * Free from added xylene and toluene. * The practical clip prevents the marker from rolling and can be attached to clothes or objects. * For permanent writing on special cleanroom paper or laminated paper in dust-free environments.
