OVPR congratulates the winners of the 1st annual Penn Labs Freezer Challenge

The Penn Labs Freezer Challenge, run by Penn Sustainability, promotes best practices in cold storage management, including refrigerators, freezers, and cold rooms. Labs submitted an online scorecard, encouraging freezer efficiency including regular defrosting, cleaning out old samples, temperature tuning, and sharing cold storage spaces. Penn’s challenge is based on the International Freezer Challenge.
Penn’s first annual Penn Labs Freezer Challenge started January 1, 2021 with a  total of 14 labs registered.

We congratulate the three winning laboratory groups:

1st Place: Cremins Lab in Epigenetics, Perelman School of Medicine & School of Engineering and Applied Science
