My Project

Performing gel electrophoresis allows the students to have a hands on experience with DNA and gives them the opportunity to physically view the DNA samples. Currently, in order for us to power the gel electrophoresis chambers, we have to use 5 9V batteries per group. That's 25 batteries per class currently and the price of these batteries adds up. These batteries also can't be reused afterwards.

These power supplies are able to power two gels simultaneously and are able to be reused, so would be a great investment for this lab.
