Glutaric dialdehyde is a efficient disinfectant, broad-spectrum, high efficiency, low toxicity, low corrosion to metal and small affected by organic matter, good stability, etc. Suitable for medical devices and resistant to moisture cream hot precision instrument disinfection and sterilization. Its sterilization concentration is 2%, commercially available glutaraldehyde are: 2% alkaline glutaraldehyde and 2% strengthening acid glutaraldehyde two kinds. Alkaline glutaraldehyde is often used in the sterilization of medical equipment, sodium bicarbonate, before the use should be added after the shake, let stand for 1 hour, the determination of pH. PH at 7.5 to 8.5, the strongest antiseptic effect of glutaraldehyde. Glutaraldehyde sterilization is a function of the monomer, when solution pH reaches 6, has the tendency of polymerization, the monomer as pH increases the polymerization is extremely rapid, can appear the precipitation in the solution, the formation of polymer after sterilization effect will be lost. Therefore alkaline glutaraldehyde disinfectant is a kind of relatively unstable, strengthen acid 2% glutaraldehyde with polyoxyethylene fatty alcohol ether as an enhancer, enhance the effect of glutaraldehyde sterilizing. Its pH lower than 5, effect of killing bacteria spore is relatively weak alkaline glutaraldehyde, but the virus inactivated effect is relatively strong alkaline glutaraldehyde, stability is good alkaline glutaraldehyde, May 28 consecutive days.
