Ionisos Medical Device Sterilisation

The French company Ionisos is one of the first companies in the world to have put ionising rays to good use for the sterilisation of medical devices. Originally known as Conservatome (from 1958 to 1993), Ionisos came into being in 1993 following a merger between Conservatome and Amphytrion. Ionisos now offers cold sterilisation for a range of applications, including:

  • Disposable medical supplies
  • Items of packaging: bottles, capsules, stoppers
  • Pharmaceutical industry raw materials or finished products

After different acquisitions, in 2004 further progress in their expansion policy allowed Ionisos to take over COFRAR, a leader company in engineering and realisation of e-beam sterilisation.

In 2007 Ionisos was also integrated with Ionmed, a well established e-beam treatment supplier located near Madrid (Spain).

Today, with five plants using rays (four plants in France, one plant in Spain) and one plant using EO, Ionisos is indisputably a major partner in sterilisation in Europe:

  • Three plants in gamma rays: Dagneux (near Lyon), Sablé (near Le Mans), Pouzauges (near Nantes)
  • Two plants in beta rays 10MeV: Chaumesnil, 10Mev – 20kW (near Troyes), and Ionisos Iberica in Tarancon, 10Mev – 80kW (near Madrid)
  • One plant using EO: Sterylene in Gien (near Orleans)

The Cobalt 60 gamma ray

The gamma ray from Cobalt 60 is safe, reproducible and immediately useable with a high penetrating power treatment.

The beta ray from an e-beam generator

The beta ray produced via an e-beam generator provides the same features, except the penetrating power, less important than in gamma rays. The beta ray, however, is more adaptable within the changing process.

EO sterilisation

Ionisos also offers EO sterilisation using EO gas. The EO sterilisation method allows a more flexible, reliable and efficient process.

Quality sterilisation services

Years of experience and geographic implantation allow Ionisos to work with all major companies involved in medical and pharmaceutical devices. Ionisos customers are present in a vast range of businesses requiring medical sterilisation: medical devices, laboratory material, aseptic production and packaging.

Ionisos is developing a partnership with its customers based on a quality assurance contract enabling it to meet the stringent requirements of this business sector.

All Ionisos plants are ISO 9001, ISO 13485, ISO 11137, ISO 14001 approved. Ionisos is steadily audited by the GMed as it continues to work with many international companies.

More than ever, Ionisos is offering reliable, high-quality solutions to sterilisation projects for all kind of products, with all countries.
