Moist-heat sterilization of blood bags


The most suitable type of autoclaves for sterilizing blood bag systems are autoclaves in which sterilizing medium is a mixture of steam and air. This method, one of the counter pressure types of sterilization, is also called ‘air-over-steam’. It allows controlling the sterilization pressure independently of the temperature: this independence is impossible with conventional pure-steam autoclaves, as the temperature and pressure of pure saturated steam are linked by a one-to-one relation.

An article of interest: “This article provides basic information on the sterilization of blood bags systems by moist-heat. Problems of pressure compensation and steam penetration into the system parts without water inside, and the process choice between single and double autoclaving are discussed.”
