Multiple labs across UCSC’s campus have already completed the Laboratory Freezer Challenge which runs through April 2020. The challenge utilizes friendly competition to optimize sustainability of freezer management in laboratories. Any type of laboratory is eligible to participate. The Freezer Challenge occurs over a five-month period where individual labs and institutions work at their own pace to implement optimal cold storage management practices. Examples of good freezer management include defrosting and removing dust from intake or coils, cleaning out your freezers, or better sample inventory practices.
