I guess you're better off calling it 'lab exchange' or something then. There's no 'science' being exchanged, just some elbow-grease work (I don't know anything about the field you're in, so I may be oversimplifying, but I know some lab techs in the life sciences and it seems you don't need to be particularly bright to do that kind of work - just have, admittedly quite thorough, skills training).
