Virkon
Virkon® is unique in its composition. Its activity is based on a buffered synergized acid peroxygen system containing a high percentage of surfactant. Virkon® is of low toxicity, non-tainting, and non-irritant. Because of its high detergency and mode of action, Virkon® can be used in an exceptional variety of situations for effective cleaning and virucidal disinfection in a single operation. Virkon® can be applied manually or through all types of cleaning and spraying equipment. The readily soluble effervescent tablet fully dissolve in lukewarm water in 3 to 4 minutes giving a clear pink solution. Virkon® consists mainly of inorganic salts. DETERGENT SANITIZER: Virkon® passes the AOAC germicidal and detergent sanitizer test at a concentration of 0.5% (1:200). DIRECTIONS FOR GENERAL USE: CAUTION: animals must be removed from the immediate area during disinfection. For cleaning and disinfection of surfaces, equipments and non-critical medical devices: Remove heavy soil deposits then thoroughly wet surfaces to be disinfected with a 1% W/V solution of Virkon®, using a mop, sponge or cloth, as well as by spraying. A minimum contact time of 10 minutes is required. For laboratory equipment and bowls, scrub heavily soiled instruments or utensils and soak in a 1% W/V solution of Virkon® for a minimum of 10 minutes (do not exceed 30 minutes for metal objects). For delicate medical devices (i.e. stethoscope, etc.), remove all organic material by cleaning and then thoroughly spray the device with a 1% W/V solution of Virkon® and allow 10 minutes of contact time before wiping. Rinse with potable water equipment to be in contact with food. Do not re-use a solution in which contaminated material has been soaked. The solution is stable for 7 days at room temperature. IMPORTANT NOTE: In animal premises where there has been a disease outbreak and/or the mortality/morbidity rates are higher than normal and the causative agent has been determined by a pathology laboratory to be one of those listed in Table 1, the contact time/dilution rate indicated should be used. For a complete listing of microorganisms against which Virkon® is effective, refer to the Efficacy Charts 2, 3, and 4.
