Which one should you choose?
A Porous load refers to the items being sterilized (dry items). Only after adequate air removal has occurred from within or around these items can there be adequate steam penetration and successful sterilization. These items may be glassware, surgical instruments, syringes, tubing, fabrics etc.
The sterilization of liquids is very different from a porous load as air removal is not critical. Sterilization is dependent upon steam contacting the container which houses the liquid product, therefore relying on the water inside of the product to create a steam environment within the container where the BI should be placed.
