Dr. David Weiss uses the 66-Omni90 in Undergraduate Research at the University of Colorado at Colorado Springs

The University of Colorado at Colorado Springs (UCCS) is primarily an undergraduate institution. As such, incoming faculty often start off with much less start-up money than faculty at research institutions. One important factor for me in acquiring an 66-Omni90 was that it was less expensive than computer controlled instrumentation. It is also an analog instrument and can be used with analog X/Y recorders that are typically found in undergraduate laboratories.

In addition, since UCCS serves mainly undergraduates, students start in my laboratory as early as their freshman year of chemistry. That way I can train them early and hopefully they will continue on in the lab after some experience. Having instruments that are user-friendly is important in getting students adjusted to the laboratory. There are some students who shy away from laboratory research because they are afraid of instrumentation. However, my students find the 66-Omni90 easy to operate and they feel completely comfortable using it.

The 66-Omni90 can also be used in conjunction with commercial analog-to-digital (A/D) converters to collect data with a computer if needed. In fact, in addition to an analog X/Y recorder we have used a Powerlab A/D converter and a computer to collect data. Students also like this format and it makes them feel that they are working in a modern high tech laboratory. This format is still cheaper than buying a computer controlled potentiostat and allows you to collect data in the analog or digital mode. Overall, the 66-Omni90 is a sturdy, reliable instrument that students feel at ease with and will allow you to perform the quality research that you expect.

Background on Dr. Weiss:

David Weiss received his Ph.D. in Chemistry from the University of Kansas (KU) in 1997 performing his graduate work under the direction of Ted Kuwana. After graduation, he did postdoctoral research at KU with Craig Lunte on an NCI Training grant developing new methods of analysis for biomarkers and drugs in physiological solutions using capillary electrophoresis. After teaching at Bucknell University as a Visiting Professor he is now an Assistant Professor of Chemistry at the University of Colorado at Colorado Springs. His research using the 66-Omni90 focuses on development of new biosensors for screening and monitoring diseases.
