In the realm of sterilization, chemical indicators are a must have, but they are not all made equal. Here's an outline of the different types of chemical indicators.
This is because before than 1940s; scientists believed that there was no single quality assurance technique that will guarantee that an item is definitely sterile and that it only confident that the problems designed for sterilization are actually satisfied.
