The possible use of sodium hypochlorite solution buffered to pH 7.6 and containing 100 ppm available chlorine (avCl) for disinfecting fibrescopes was investigated. A flexible fibrescope experimentally contaminated with Pseudomonas putida, Mycobacterium fortuitum, or Bacillus subtilis spores was effectively disinfected within 10 m in repeatedly and without any observable adverse effect on the instrument. The corrosive nature of buffered hypochlorite was investigated by immersing various fibrescope components and metal wires in solutions of different strength for long periods and examining them for damage. Stainless steel, platinum, glass, Teflon, polythene and epoxy resin were apparently unaffected whereas polyurethane, rubber and other metals tested were damaged to different extents. Buffered hypochlorite solutions may have many applications pertaining to the disinfection of items which are either thermolabile or require rapid effective disinfection.
研究了使用pH值缓冲至7.6且含有100 ppm有效氯（avCl）的次氯酸钠溶液对纤维内窥镜进行消毒的可能性。用恶臭假单胞菌、偶然分枝杆菌或枯草芽孢杆菌孢子进行实验污染的柔性纤维内窥镜，在10分钟内可有效消毒，且对仪器无任何明显不良影响，可反复进行。通过将各种纤维内窥镜部件和金属丝长时间浸泡在不同强度的溶液中并检查其损坏情况，研究了缓冲次氯酸盐的腐蚀性。不锈钢、铂、玻璃、聚四氟乙烯、聚乙烯和环氧树脂显然未受影响，而测试的聚氨酯、橡胶和其他金属则有不同程度的损坏。缓冲次氯酸盐溶液可能在对热不稳定或需要快速有效消毒的物品消毒方面有许多应用。
