The Cleanroom Revolution

Over 15 years of research on different disinfection and decontamination processes form the basis of our know- how.

For example, the gaseous hydrogen peroxide decontamination (H2O2) developed by Ortner is considered a true milestone in the microbiological field of cleanroom technology- and a major contribution to a turning point in medical and pharmaceutical decontamination technology.

H2O2 decontamination is the disinfection by means of vaporized hydrogen peroxide. This system is both safer and more environmentally friendly than previous methods such as those using formaldehyde.

The advantages are clear: easier applicability for users and an important contribution to environmental protection.

The H2O2 decontamination technology can be used almost everywhere and is effective even where other methods cannot be used or are very difficult to use. Preferably it is used
in the pharmaceutical industry, medical technology, animal breeding, in hospitals, in biochemical testing facilities and in the food industry.

Safe & Environmentally Friendly

As an excellent oxidizing agent, hydrogen peroxide has the ability to kill or inactivate bacteria, viruses, fungi and spores without leaving any residue.

The H2O2 decontamination technology is environmentally friendly and safe because the splitting into water (H2O) and oxygen (O2) does not produce any visible or toxic residues and the discharge into the open air is permitted.

Arguments for H2O2 decontamination

  • Safe & effective
  • Fast & validatable
  • Wide range of applications

Working Principle

The biocidal effect of hydrogen peroxide results from its high oxidizing capacity and leads to rapid effectiveness against most microorganisms due to the formation of free radicals.

The attack of the H2O2 takes place in different ways, such as on the bacterial cell, the cell wall or the cytoplasm, as well as the DNA/ RNA. In the process, coat proteins of the microorganism are altered and thus denatured.

Denaturation leads to inhibited metabolism and ultimately to the death of the microorganism.

Today, the issue of effective and rapid decontamination of surfaces is even more important than ever before.

The statement of a renowned bio- laboratory partner from Germany on the efficacy of H2O2 procedures against coronavirus is promising:

"H2O2 technology has a good mode of action against coronavirus:

Due to the same virus structure of MVA (Modified vaccinia virus Ankara) and coronavirus, the two are comparable. And here we have had very good experience with H2O2: depletion of MVA by gaseous H2O2 decontamination has been shown to work well."
