Chamberlock



The Chamberlock is the room at the end of each Test Chamber that contains an elevator leading to the next one. The Chamberlock is the most common fixed-end goal of any test chamber, and its entrance is always covered by a Material Emancipation Grill to vaporize any objects that pass through and remove any previously-placed portals. Chamberlocks appear in most levels of both Portal and Portal 2.
