An ultra-low temperature freezer is a laboratory device used to store samples, usually at temperatures below -80°C. When choosing an ultra-low temperature refrigerator, you need to pay attention to the following points and precautions.

Selection points
Temperature range: ULT freezers typically have a temperature range between -80°C and -150°C. It is necessary to select a temperature range that suits your experimental needs.
Capacity: Choose the capacity that suits your experimental needs. The capacity of ultra-low temperature refrigerators is usually between tens of liters and hundreds of liters.
Control method: Choose the control method that suits your experimental needs. Some ULT freezers can be controlled from a touchscreen or computer, while other models may only have simple mechanical controls.
Stability: The stability of an ultra-low temperature refrigerator is an important indicator, which means that the equipment can maintain a constant temperature to avoid affecting the experimental results. It is necessary to choose a model with good stability.
Energy consumption: The energy consumption of ultra-low temperature refrigerators is usually higher than that of conventional refrigerators, and energy-saving models need to be selected to reduce the cost of experiments.
Precautions:
Maintenance: ULT freezers require regular maintenance and cleaning to keep the unit functioning properly. When cleaning equipment, use appropriate cleaning agents and follow the equipment manufacturer's instructions.
Calibration: Periodic calibration is required to ensure the temperature control accuracy of the ULT freezer. Calibration can be performed by the device manufacturer or by a third-party laboratory.
Environment: When choosing an ultra-low temperature refrigerator, you need to consider the environment in which the equipment will be located. If the equipment is placed in a humid or easily polluted environment, corresponding measures need to be taken to avoid damage to the equipment or affect the experimental results.
Instructions for use: When using ultra-low temperature refrigerators, you need to follow the instructions of the equipment manufacturer, especially pay attention to safety matters during operation.
Quality Assurance: Choose an ULT freezer with a good quality assurance, which will ensure the performance and reliability of the unit, as well as better after-sales service and support.
