Porter Instrument has been manufacturing nitrous oxide and oxygen delivery systems for over 50 years. Nitronox Plus® is the only demand flow system that offers 0-70% adjustable nitrous oxide which allows the clinician to dial in to each patient’s specific needs vs. fixed 50/50 devices. Nitronox Plus is simple to use and helps manage your patient’s pain and anxiety during minimally invasive in-office OBGYN procedures including hysteroscopy, IUD insertion and medical aesthetic procedures.
