Low-temperature ozone sterilizer based on reactor with electrolytic cell

Low-temperature ozone sterilizer based on reactor with electrolytic cell for processing small-sized surgical and dental instruments has been developed. The maximal ozone concentration in water comprised 7.5 mg/l during 10 min of operation. It was revealed that the highest ozone concentration was achieved in 400 ml water volume. When increasing the volume to 600 ml, the ozone concentration in water was minimal. The method of neutralizing of alkaline solution from the surface of medical instruments was investigated. Samples for elimination of alkaline solution were processed in 1 % alcohol solution of phenolphthalein. It has been monitored that the time required to remove alkaline solution from the surface of medical instruments is not less than 20 min. The carried out experiments on removal of organic residues (blood) from medical instruments showed that the traces of blood were not presented on the surface after 10-min treatment (the ''Delatest'' test system was used to determine the number of blood traces).
