In 2001 we began a program to provide computerized data stations for our introductory chemistry laboratories. Prior to that time we were limited to 3-4 standard PC's on carts; these generally remained in our general chemistry lab but were available for use in other instructional labs.

This Web site is being expanded (August 2004) and will provide detailed description of apparatus, software and experimental modules.
