-80 Freezer Storage and Maintenance

Freezer Storage

Every lab member is assigned a section of 10x10 freezer boxes on shelves 1 and 4. In addition, every member has an assigned overflow box for all samples on shelves 2 or 3. All samples and the sample container should be labeled with the owner’s initials, date, and sample contents. Be cautious and quick when opening the freezer door, best practice for retrieving samples is to keep the freezer door open less then 2 min at a time. This helps to keep a consistent temperature in the freezer and keep the frost levels to a minimum.
