Abstract
Abstract The steam test pack (10) is comprised of a plastic tube (12) having a sterilization sensitive ink imprinted indicator card (14) and a biological indicator (16) therein. The ends (18) of the plastic tube are capped by plastic caps (22) having an aperature (24) extending therethrough, and having an inner diameter (20) slightly larger than the outer diameter of the tube. This combination creates the inhibiting menas to control the flow or exchange of a gaseous medium into the tube and then to the biological indicator.
