CUTTING-EDGE PRACTICES

Want to go above-and-beyond standard cold storage best practices? Incorporate some of these ideas into your lab's daily routine and watch the points add up... and the time you spend rooting around for samples go down.

Sharing
Sharing equipment is an oft-overlooked but extremely effective way of reducing the operating costs of a lab.  If you are sharing space in a refrigerator or freezer with another lab you've likely not only saved some money, but you're also going to earn some points in this challenge.

Barcodes
Barcodes are an excellent way to keep track of samples. Any refrigeration units that contain barcoded samples should be accounted for in this section on the scoresheet.

Trying Room Temperature Sample Storage (RTSS)
RTSS is becoming more common for DNA, RNA and plasmids.  It is particularly useful for shipping (eliminating the need for dry ice), or in field collection (eliminating the need for refrigeration).

Credit will be given for trying RTSS per well plate or set of 25 tubes. 

Trying Room Temperature Sample Storage (RTSS) for Reagents
Not only is RTSS becoming popular for samples, it's also being used for reagents and diagnostic kits.

Credit will be given for storing reagents or diagnostic kits at room temperature that were previously stored at colder temps.

Adopting Room Temperature Sample Storage (RTSS)
If your lab has fully adopted RTSS for your samples, congratulations!  Let everyone know how much space you've saved in your freezers by filling in the score sheet.

Credit will be given per well plate, set of 25 tubes, or number of 2" boxes.
The Freezer Challenge is a program coordinated by the non-profit organizations
​My Green Lab and the International Institute for Sustainable Laboratories, and sponsored by various companies with an interest in promoting the most energy efficient cold storage options.
