2021 Penn Labs Freezer Challenge

The Penn Labs Freezer Challenge is designed to promote best practices in cold storage management. The Freezer Challenge covers all forms of cold storage, including refrigerators, freezers, and cold rooms. Labs participating in the challenge will be asked to submit an online scorecard, encouraging them to take actions toward freezer efficiency including regular defrosting, cleaning out old samples, temperature tuning, and sharing cold storage spaces. Sign-ups are accepted on a rolling basis. The challenge officially starts January 1, 2021, and the deadline to complete the challenge is April 15, 2021. First, second, and third place winners will be awarded swag basket prizes containing reusable items like Nalgene water bottles, canvas bags, metal reusable straws, and more!

We also encourage you to enter the International Freezer Challenge. Awards for the international challenge includes financial incentives, a stipend to attend the I2SL conference ( and recognition in the journal Nature.
