NuPrep Skin Prep Gel

NuPrep skin prep gel is the standard many technicians reach for before applying electrodes for EEG, EKG/ECG, EMG, or evoked potential recordings. Made by Weaver and Company, this mildly abrasive gel removes the dead skin cells, oils, and light debris that raise impedance and introduce noise into a tracing. Clean electrode sites mean cleaner signals — and fewer redos.

The reason NuPrep works so well comes down to what it is: a gentle exfoliating gel with a fine pumice content that lightly buffs the outer layer of skin without the harshness that irritates sensitive patients. You apply a small amount at each site, rub it in with gauze or a cotton swab, wipe away the residue, and place your electrode. Lower skin impedance translates directly into better electrode adhesion and more reliable readings across a monitoring session.

We carry NuPrep in the 4 oz. tube, the size most clinics and neurodiagnostic labs prefer because it covers a high volume of preps without the waste of single-use packets. It's a workhorse in sleep labs, cardiology departments, neurology practices, and EMS settings — anywhere consistent electrode contact matters.

A common question: how is NuPrep different from a conductive paste or transmission gel that stays on the skin? NuPrep is a prep gel — it's meant to be applied and then removed before electrode placement, priming the site rather than serving as the conductive medium itself. Many technicians pair it with a separate conductive paste or gel for the electrodes. It's safe for use across the body, though care should be taken near the eyes and on broken skin.
