North Lab I and II

In order to access North Labs I or II in the Commonwealth Building, you must travel to the third floor, either using the lift or the stairs. Both of these labs are located at opposite ends of the same corridor and they are well sign-posted once you have made it to the third floor. There are lockers in the corridor to store your personal items, and you should remember that no eating or drinking is allowed in the labs at any time. You may therefore wish to arrive a little early to lab classes to have something before you go in.
