Aerial Disinfection Uses Cases
Vibrating membrane nebulization of H2O2: a proven technology for biosafety in pharmaceutical and medical environments
Certain environments and specific sectors of activity are particularly sensitive to the risk of surface colonization by micro-organisms, which can lead to the contamination of patients or operators. The risk of surface infection is particularly high in areas where micro-organisms are handled, such as biological research, biotechnology, anatomy, autopsies, and medical and veterinary laboratories. In order to eliminate this risk, it is necessary to carry out daily cleaning procedures for floors, benches and equipment.
This can be achieved by having some of the staff regularly clean the surfaces and equipment. However, this can be complicated in certain environments or when faced with stringent safety and bio-decontamination standards. It is in this context that the maintenance, cleaning and hygiene management of all or part of the surfaces can be complemented by aerial disinfection mechanisms (ADS). These are called “biocleaning” requirements, where the hygiene requirements go beyond the notion of cleanliness alone and tend towards the total or partial disinfection of spaces.
Against the backdrop of this need for ADS, TEKCELEO H2O2 nebulizers can achieve very good results. It is useful to specify that our products are useful for the method of disinfection called “non-directed dispersants”, i.e. without human presence and with the help of particular automatic devices. Our vibrating membrane nozzles can be used for two types of treatment:
- “Dry fog”, in which the product is sprayed in micro-droplets of about 4 to 12 microns (depending on the nozzle used); this type of treatment works very well with hydrogen peroxide. This treatment does not produce a wetting effect on the treated surfaces, but can limit the spectrum of liquids and disinfectants used.
- Cold atomization, in which the product is sprayed in micro-droplets larger than 12 microns, which has a wetting effect around the diffuser. This treatment is less precise than the dry fog method, but allows the vast majority of disinfecting liquids to be used.
Our piezoelectric atomization technology with a microperforated vibrating membrane achieves very good performance for the treatment of surfaces by airborne disinfection using “non-directed dispersants”. The ability to disinfect inaccessible areas is an essential quality of our atomization technology, especially in very high-biosafety settings such as cleanrooms. Our technology is suitable for every environment, miniature and affordable, which is one of its main advantages against other technology, such as vaporized hydrogen peroxide (autoclave, dry heat…).
Achievements and examples with our nebulizer
- TEKCELEO vibrating membrane nozzles have been incorporated into a portable medical and pharmaceutical disinfection robot. Our nebulization technology is used in a hand-held ASD device for remote disinfection of variable surfaces. The device can operate any kind of disinfecting liquid.
- Our product P&S-360 has been used for disinfection of biological safety cabinets (BSC) with hydrogen peroxide. As part of our collaboration with some laboratories and universities, TEKCELEO provides “turnkey” kits that can be quickly used to be tested in ASD use.
