If you choose an ENERGY STAR certified laboratory deep freezer, you can use up to 33% less energy than a regular one. This means you pay less for power. Some freezers have special technology that changes how much energy they use depending on how full they are. Getting a new, energy-saving freezer can cut your energy use in half.
Tip: If you set your freezer from -80°C to -70°C, you can save up to 30% on energy costs and still keep your samples safe.
You need to keep your freezer free of ice so it works well. There are different ways to defrost:
Defrost System | Description | Advantages |
|---|---|---|
Manual Defrost | You empty and turn off the freezer to melt ice. | No need for automatic schedules. Protects sensitive items from temperature changes during moves. |
Auto Defrost | The freezer removes frost by itself on a schedule. | Saves time and keeps temperatures stable, protecting your samples. |
Manual defrost freezers need more work because ice builds up.
Auto-defrost freezers use heat to melt ice, but this can make the temperature go up for a short time.
Frost-free systems are best for sensitive samples because they keep the temperature steady.
The U.S. Centers for Disease Control says you should use a laboratory-grade freezer with a frost-free, automatic defrost cycle. Good airflow is important too. Do not pack your freezer too full. Leave space between boxes and shelves so air can move and keep the temperature even. Some freezers use special insulation to keep the cold in and the heat out.
You need to keep your samples safe from accidents and power problems. Laboratory deep freezers have many safety features. The table below lists common alarm types and what they do:
