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.
Top 5 Questions You Should Ask When Buying a Cold Storage Equipment
- How is the product manufactured? Ask about the quality of the materials used and the product life.
- What is the warranty? What does it include and for how long? Will anything void the warranty?
- How green is the product? Ask the company to provide details on energy efficiency and have them relate it to your return on investment (e.g. in four years will you save enough money in energy costs to pay for your freezer/fridge?).
- How much sample capacity are you getting for your space?
- What are the optimal voltage/wiring conditions for running the fridge/ freezer? If the building is older, will low voltage or voltage fluctuations affect the performance of the freezer/fridge?
