A container for creating a microenvironment is disclosed. The container includes a shell, a door and a plurality of supports having a unique design which are used to securely retain items, such as silicon wafers, in a spaced apart parallel relationship. The supports are removable. An electrical path is provided to ground the supports. Kinematic coupling structures are also provided for positioning the container on a surface so as to, for example, properly align the door with the port of a wafer processing tool.
