Stanford research technician Darren Morrow checks the temperatures on a new high-efficiency freezer containing DNA samples at the Herrin Labs.
Stanford's Department of Sustainability and Energy Management is urging researchers to go green and get rid of their old ultra-low-temperature freezers. Labs get cash to buy new energy-efficient freezers or use new technology to store biological samples at room temperature. Labs at Stanford have the chance to go a little greener this year, thanks to the Ultra-Low-Temperature Freezer Retirement Program. The initiative, led by the Department of Sustainability and Energy Management, aims to decrease the number of laboratory freezers on campus. For researchers who can't live without a freezer, the program also offers incentives to upgrade to a more energy-efficient model. Laboratory freezers store tissue, blood and DNA samples at temperatures as low as minus 80 degrees Celsius, depending on what material is being stored and for how long. They can protect frozen samples from damage for decades.
