1 Cleaning of container and utensil

1.1; soak the vials with clean water for an hour, and then clean them with 500 Ultrasound for 10 minutes. Next, clean the vials three times with pure water (you can also use injecting water or bacteriostatics water on the condition of sterility and none heat source, similarly hereinafter). Then, place the vials upside down on the tray and cap them and put them under the condition of 180 for two hours. At last, store and cool them in the sterilized cabinet, opening the ultraviolet lamp

1,1;西林瓶用清水浸泡1hr,超声500W清洗10min,用纯水(无菌无热源,可以用注射水或抑菌水代替,下同)冲洗3次,倒置于托盘,加盖,T180℃2hr干烤灭菌灭热源,在无菌柜中开紫外灯存放冷却备用。

1.2; soak Butyl Rubber Stoppers with 95%Alc for 12 hours and then clean them three times with pure water, 15minutes with 500 Ultrasound. Next, wrap them loosely with for layers of gauze which have been clean with pure water. Then use 115vapor to sterilize them for 30 minutes. At last, store and cool them in the sterilized cabinet, opening the ultraviolet lamp

1,2;丁基胶塞用95%Alc浸泡12hr,用纯水洗三遍,超声500W清洗15min,用纯水冲洗3遍。用纯水洗净的四层纱布很松地包裹丁基胶塞,115℃蒸汽灭菌半hr,在无菌柜中开紫外灯存放冷却备用。,

1.3Use pure water to clean the filling head three times, then clean with 500 Ultrasound for 15 minutes, and again clean three times with pure water. Then put it in the clean tip box. Next, use 115vapor to sterilize them for 30 minutes. At last, store and cool them in the sterilized cabinet, opening the ultraviolet lamp

1,3;灌装枪头纯水洗三遍,超声500W清洗15min,用纯水冲洗3遍。放到洁净的枪头盒中,115℃蒸汽灭菌半hr,在无菌柜中开紫外灯存放冷却备用。

1.4; store the transfer liquid gun in the sterilized cabinet, opening the ultraviolet lamp

1,4;移液枪在无菌柜中开紫外灯存放备用

1.5; install ultrafilter. First, clean it with 0.5mol NaOH for 10minutes and then clean it until it reach pH7 with pure water. At last, store it in the sterilized cabinet, opening the ultraviolet lamp

1,5;超滤器安装,用0.5mol清洗10min,用纯水冲洗到pH7,无菌柜中开紫外灯存放备用
