The moorVMS-ION iontophoresis controller is intended to provide the driving force for a range of clinical research applications that require drugs to be delivered by iontophoresis in order to monitor any associated changes in tissue perfusion.

The moorVMS-ION iontophoresis controller is intended to be used in conjunction with a range of Moor Instruments products, including:

  • Monitors: moorVMS-LDF, moorVMS-OXY
  • Imagers: moorFLPI-2, moorLDI2, moorLDLS2
  • Software: moorVMS-PC

Iontophoresis is a method of delivering ionic drugs into the skin. Normally non-lipophilic drugs, e.g. acetylcholine chloride, would remain on the skin surface and very little would diffuse into the skin. Iontophoresis is performed using an electrically conductive chamber filled with the non-lipophilic drug solution and a conductive pad, placed in contact with the patient’s skin. A small current flows between the chamber and conductive pad, causing the ions of the drug to convey the electrical current as they pass into the skin.

Please note: the moorVMS-ION iontophoresis controller it is not intended to deliver drugs for the treatment of illness or disease.

The following products are AVAILABLE TO BUY ONLINE and work with the moorVMS-ION
