NuPrep® and Ten20® – Professional Gels for Ophthalmic Electrophysiological Examinations

In ophthalmic electrophysiological examinations, the quality of the contact between the electrode and the skin directly affects the accuracy of the results. For stable and reproducible signals, our clinic uses professional reference gels: NuPrep® 114 g and Ten20® 228 g, both manufactured in the USA.

These gels are commonly used in procedures performed with the Retimax Advanced Plus, such as:

  • Electroretinography (ERG)
  • Visual Evoked Potentials (VEP)
  • Electrooculography (EOG)

NuPrep® 114 g – Professional Skin-Prep Gel
NuPrep® prepares the skin before electrode application by reducing electrical impedance and improving conductivity.

Benefits:

  • Gently cleans the superficial skin layer
  • Reduces impedance and artifacts
  • Ensures optimal electrode-skin contact
  • Safe and well-tolerated

Uses:

  • Skin preparation for ERG, VEP, and EOG
  • Other neurological investigations with surface electrodes (EEG, EMG)
  • Medical research and neurophysiological monitoring

Ten20® 228 g – Professional Conductive Paste
Ten20®
fixes the electrodes on the skin, maintaining constant conductivity and stable signal throughout the examination.

Benefits:

  • Secure electrode fixation
  • Excellent and uniform conductivity
  • Reduces interference and signal loss
  • Easy to clean after the procedure

Uses:

  • Electrode fixation for VEP, ERG, and EOG
  • Surface EEG and EMG
  • Intraoperative neurophysiological monitoring
  • Transcutaneous electrical stimulation procedures (TENS) with compatible electrodes

Why we use NuPrep® and Ten20® in our clinic:

  • Accurate and reproducible results
  • Clear, interference-free signals
  • Maximum patient comfort
  • Perfect compatibility with electrodes and modern equipment
  • Certified products manufactured in the USA, internationally recognized

These gels ensure that every ophthalmic electrophysiological examination in our clinic provides precise and reliable data, contributing to the accurate diagnosis of retinal and visual disorders.
