Maintaining samples at an optimal temperature while in storage is vital for many lab professionals and this makes choosing the right freezer or refrigerator a crucial task. While the average kitchen freezer operates at about -20°C, laboratory variants have a much wider range of options depending on the storage conditions needed. For example, lowtemperature laboratory freezers will achieve temperatures of -40°C to -85°C, much lower than their kitchen-based counterparts. When selecting a freezer or refrigerator for your lab, it is important to know what specific storage requirements you’ll need, such as the temperature range or space available.
