Experiments Go Microscale--Used with permission of ACCC. Chernushenko, D. Greening Campuses, 1996. Chapter 4. A 1995 survey of American colleges and universities found that more than ten percent have adopted "microscale" laboratory experiments. The microscale concept was first developed and popularized by chemistry professors at Bowdoin College (Brunswick, Maine). The principle was to modify standard class-room chemistry procedures in a way that uses a fraction of the typical quantity of chemicals. The goal was to reduce the cost of chemical purchase and disposal and to minimize the risks that accompany the use, storage and disposal of chemicals. The goal was to reduce the cost of chemical purchase and disposal and to minimize the risks that accompany the use, storage and disposal of chemicals. After publishing articles on the subject of microscale experiments in the mid-1980's, positive response was so great that Bowdoin faculty decided to develop a textbook and a newsletter on microscale chemistry. Since then, many further texts have appeared and specialized equipment developed. Special microscale glassware is smaller and less breakable. Though an initial investment is required when an institution switches to microscale equipment and textbooks, the cost should be offset by purchase and disposal savings. A crucial benefit of "going microscale" is a safer environment for students and instructors, including better air quality. Adapted from U.S. Environmental Protection Agency documents. |
