A sterilization tray is disclosed herein that may be used to facilitate preparation of an endoscope for sterilization and increase the likelihood that the endoscope will be properly sterilized. The sterilization tray may be fabricated from a flexible and vapor-permeable sheet. Cutouts may be disposed through the sheet to define standoffs that are foldable away from the sheet. A first standoff may include a first contoured portion disposed therein. The tray may also include a second standoff that has a second contoured portion and a third contoured portion disposed therein. The third standoff may include a locking tab disposed on a free end of the third standoff. A positioning tab may also be disposed on the third standoff. The sterilization tray may also include a dry booster to which an endoscope may be connected.
