Evolution of (EtO) Gas Diffusion Sterilization since 1958

Dr. Harold W. Andersen, a surgeon from New York, invented -and subsequently patented-- a unique gas diffusion sterilization method of sterilizing using ethylene oxide. This method remains the best ethylene oxide sterilization method for low to moderate volumes of delicate items.

Andersen Products was founded by Dr. Andersen who is also the company's current Chairman. While working as a surgeon at Bellevue Hospital in New York City Dr. Andersen invented a better apparatus for gastric drainage. His colleagues began asking for the new device, which led to the formation of Andersen Products, or Anpro®.
