This paper discusses the implementation of several laboratory systems that are used for remote experimentation via the Intemet. The paper discusses the equipment and software developments for four systems that are used in teaching and research in controls systems and unit operations laboratories: -- a three-tank level control system (UNM) -- a twelve-tray distillation column (UTC) -- a shell-and-robe heat exchanger (UTC) -- a gas-fired water heater (UTC) Each lab equipment system is connected to a dedicated control computer that allows real-time operation and control manipulation of that equipment via the Internet. The interaction is with web browsers with a LabVIEW plug-in. The computers collect all the data from the experiment. The systems are available 24/7 for student use. The experiment control panel can be viewed remotely (by any number of students) as they proceed via the Web and the (data files and graphs) are available on the web as the experiment proceeds and after the experiment is finished. The paper discusses how the remote experiments are used for teaching and research. We will present the pattern of student use of the equipment and the experiences of the students in developing and using the systems.
