Introducing STERI-7 XTRA

Reactive Barrier Technology is a specialised micro emulsion which provides an optional sustained release system – this means that the reactive barrier can be turned on or off depending on the situation. It’s simple, if you rinse STERI-7 XTRA after application you remove the reactive barrier, if you leave STERI-7 XTRA to dry you enable the Reactive Barrier Technology giving you added Biosecurity and protection between cleans.

Take a desk, dining table, or even a kitchen worktop, they are all vulnerable to contamination. Spray STERI-7 XTRA on the surface and leave to dry. Seconds later and STERI-7 XTRA has killed the bacteria, viruses, fungi, spores and moulds up to 99.9999% on that surface. STERI-7 XTRA doesn’t stop there. When STERI-7 XTRA has dried, a barrier is created which re-activates in the presence of any moisture.

For bacteria, viruses, fungi, spores and moulds to reproduce, they must contain moisture. However the moisture they need, although it's microscopic, is enough to activate STERI-7 XTRA's Reactive Barrier which effectively wipes them out. Effectively the germs kill themselves, pathogen suicide no less.

We wanted to prove STERI-7 XTRA's Reactive Barrier Technology could be used to promote Biosecurity, so we asked an Industry recognised independent analytical laboratory to put STERI-7 XTRA and the Reactive Barrier Technology to the test.

Using an adapted version of surface test protocol EN 13697 under ‘Dirty’ test conditions, STERI-7 XTRA was diluted with hard water, as hard water weakens a disinfectant’s efficacy. Spores, fungi and bacteria were chosen because these are some of the toughest pathogens to damage, never mind kill. If they could be killed under these conditions we knew STERI-7 XTRA could deal with almost anything.

The lab set their parameters. STERI-7 XTRA was sprayed onto stainless steel slides and left to dry. Once dried they were inoculated with selected bacteria, spores and fungi. After 1 minute contact time, the slides were swabbed with a dry sterile swab and analysed. STERI-7 XTRA killed the lot.

5 minutes later the same stainless steel slides were inoculated again, left for 1 minute contact time and swabbed with a new dry sterile swab. STERI-7 XTRA again killed the lot.

This was repeated at 30 minutes, 60 minutes, and even 72 hours later.
Guess what? Yes. STERI-7 XTRA again killed the re-inoculated pathogens.

Testing was carried out to assess the efficacy of STERI-7 XTRA alone, no mechanical agitation was employed.

What does this mean for you?

As has been proven, STERI-7 XTRA’s unrivalled Reactive Barrier Technology continues to be effective between cleans. And although it is extremely harmful to pathogens, when used at manufacturers recommended dilutions it is not harmful to anything or anyone. All of STERI-7 XTRA’s ingredients have worldwide approval.

Product Data Sheets

STERI-7 is a multi-purpose biocidal cleaner that also works as a high level disinfectant. It cleans practically any surface or material, eradicating bacteria, spores, fungi, yeasts and viruses.

What makes STERI-7 your ideal cleaning solution is that it keeps treated areas contamination free between cleaning cycles. This is because it goes on working once dried, something no other disinfectant is proven to do.

The result is round the clock Biosecurity, with no window of opportunity for germs to re-establish themselves.
