• Disposable PTFE coated stainless steel needle electrodes have a super-flexible PVC insulated leadwire ending with a standard touch proof connector.
• Teflon coated needle electrodes are fully insulated, with a clear Teflon overcoat, except for the conductive needle tip. The coating prevents the needle from making contact with the subject except at the very tip of the needle, which is exposed.
• For applications that require better contact between the electrode and the subject to record a good signal, abrade the needle to remove the Teflon coating.
