UV sterilizing technology

UV-C is the most energetic portion of ultraviolet radiation; it can cause electronic excitation leading to the breaking of chemical bonds and the formation of unpaired electron species, known as radicals, that are highly reactive and can damage DNA and cell replication deactivating all kinds of microorganisms from viruses to fungi. The technology to generate UV-C is based on a bulb that contains gaseous mercury which, when subjected to electricity, emits an ultraviolet radiation, 95% of which is at 253.7 nanometers. This wavelength is in the region of maximum germicidal effectiveness and is highly lethal to virus, bacteria and mold spores.
Quality Control
Regular implementation of the cleaning procedure of cryotanks using NTERILIZER (as described in the page STORAGE on this website, can reduce or eliminate altogether the sanitization procedure.
However, frequency of decontamination and servicing of LN dewars depends on their volume, the presence of infectious samples, the number of stored embryos (straws, vials), the frequency of LN refilling and moving germplasm in and out. It should be kept in mind that non-sterile LN, common air pollutants, and microorganisms attached to the outside of embryo containers will contribute to the accumulation of contaminants in a dewar over time. Therefore, the IVF practitioners must take into account the above factors to determine appropriate intervals between periodic decontaminations of LN dewars.
NTERILIZER now offers a quick and reliable service to check periodically the sterility status of the cryotanks. To enquire about the availability of the service in your country, please contact us.
