OK器械消毒液为含2％戊二醛的复方消毒剂。对枯草杆菌黑色变种芽胞作用3h，杀灭率为100％，作用10min可将HBsAg抗原性破坏。杀菌效果随温度升高而增强，随pH下降、悬液中含有机物、复方中去除亚硝酸钠而减弱。所试金属，除对铝有轻度腐蚀外均基本无腐蚀。存放于54～57℃14d．戊二醛浓度下降2．97％。
OK Instrument disinfectant with 2% glutaraldehyde compound disinfectant. Bacillus subtilis black mutant spores 3h, the killing rate was 100%, the role of 10min HBsAg antigen can be destroyed. Bactericidal effect increases with temperature, with the pH decreased, the suspension containing organic compounds, the compound to remove sodium nitrite and weakened. The metal tested, except for mild corrosion of aluminum are basically non-corrosive. Store at 54 ~ 57 ℃ for 14 days. Glutaraldehyde concentration decreased by 2.97%.
