Abstract
A vacuum-sealable hatch that is vacuum sealed to a surface of a passthrough light sterilization device, and related methods of use, consists of a hatch body having at least a portion adapted to fit within an opening of the treatment chamber and a flexible piece attached to the hatch body. The flexible piece extends peripherally from the hatch body and includes a seating portion which is adapted to be vacuum sealed to a seating region of an interior surface of the treatment chamber. The hatch body and the flexible piece seal the treatment chamber from the outside environment, thereby preventing the free flow of microorganisms to and from the treatment chamber and the outside environment. In some variations, at least the seating portion of the flexible piece is transmissive to the light treatment such that surfaces underneath the seating region are treated by the light treatment.
