Anti-static Materials for Labs
Various studies around the world reveal similar shocking facts, such as 60-90 per cent of devices are damaged due to electrostatic discharge (ESD), and 70 per cent of these failures are due to ungrounded people. So it becomes important that you take ESD control systems seriously. Otherwise, losses can be astonishingly high. You can follow simple ESD control systems using anti-static materials and achieve the highest reliability in the output
