In laboratory and clinical environments, it is important to keep perishable samples at a consistent temperature well below freezing. Minus 20 degrees Celsius is a commonly accepted baseline temperature at which to store perishable, flammable, or hazardous material, and so the freezers listed below for the most part reach -20 °C. Some freezers have -20 °C as their only setting, while other freezers are capable of different temperature ranges from -13 °C to -40 °C. Operation voltages range from 115 to 230 V, depending on temperature range and sample capacity. A minus 20 freezer can have an under-counter, chest or upright orientation. Various proprietary foam insulation types provide good Energy Star ratings, and manual defrost systems with special thawing tubes help protect against thaws and dehydration.
