Walkthrough

 * Exit the elevator and proceed through the door on your right.
 * Place a portal on the other side of the Laser Field, and the other on the side you are on. Go through the portal.
 * Walk over to the plasma wall and shoot the last portal on the other side.
 * Go through the other portal. Take the cube that came out of the dropper and place it on one of the buttons in the first area.
 * Go back to the room with the cube dropper, and place a portal under the dropper. Place the other portal on the ceiling near the plasma wall.
 * Jump into the portal under the dropper, and as you come out of the other move your ceiling portal to the floor where you're about to land.
 * As you launch up into the dropper, shoot another portal through the hole off to the side. Go through the other portal to get in this area.
 * Go through the door to the right and shoot a portal on the wall near the ceiling. Go through your other portal.
 * Proceed through the door and jump into the broken vacuum tube. (There are invisible clips to help you get in, you do not need to jump on an object.)
 * Once in the tube, go left and into the downward tube. You will land on some cubes, which fall out of the dropper.
 * Shoot a portal on the other side of the plasma wall and the other on the floor where you are.
 * Bring a cube through the portal and place it on the other button.
 * Proceed to the Chamberlock.
