ELECTRODES
In selecting the application site for any style of electrode, care should be taken that:
1)
Electrode site is dry and free of excessive hair.
2)
Electrode is not placed over scar tissue or on an area of established erythema or with a lesion of any kind.
3)
Skin is properly prepared. (Prepare the skin at the electrode site. Use the ELPAD to lightly abrade the skin
surface. Use a brisk dry rub to prepare the application site. Avoid excessive abrasion of the skin surface.)
EL450 SERIES NEEDLE ELECTRODES
Use for stimulation or recording in animal subjects and tissue preparations. The 28-gauge stainless steel needles
are Teflon-coated, with flexible cable terminating in 1.5 mm Touchproof connectors. 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.
Needle electrodes are shipped non-sterile, so pre-sterilization is required.
