The simplicity of application, and smooth, clean surfaces of the static-free PELCO Tabs, Carbon Conductive Tabs are a significant improvement compared to many of the other common adhesives that have been used in microscopy mounting. Both tab sides have a thick conductive adhesive (conductive inner film is 35µm and the adhesive is 45µm on each side for a total of 125µm [5 mils]) with a liner on both sides, a transparent liner and white liner respectively. They are ready for immediate use. On the other hand, the top liner does not have to be removed until the sample is ready to be mounted. This reduces possible contamination. Outgassing is negligible
