  • How Can You Ensure that Your Device Is Sterile?

    Sterility assurance is necessary for guaranteeing microbe-free medical devices. But to achieve it, how many devices do you really need to test?By Bob MichaelsTo determine the probability that a sterilization process will sterilize a device successfully, the medical device industry relies on a statistic known as the sterility assurance level (SAL). The standard recommended SAL is 10–6—meaning that there is a one in a million probability that a single microorganism will survive on a medical...
