Introduction to Program Freezer

Procedure Freezer An instrument used to freeze and protect procedure samples. It is mainly used in laboratories in biomedical research, biochemistry, molecular biology and other fields.

The working principle of the programmed freezer is to quickly freeze the sample by placing it in a low-temperature environment, thereby slowing down or stopping the chemical reactions and biological activities in the sample. It typically uses liquid nitrogen or refrigerant to provide a cryogenic environment. The program freezer is also equipped with a temperature control system that can accurately control the freezing temperature to adapt to different types of samples.

Key features of program freezers include:
1. Efficient freezing speed: The program freezer can quickly freeze samples to the required temperature, thereby reducing losses and changes during the freezing process.
2. Precise temperature control: The programmed freezer can accurately control the freezing temperature and stably maintain the set temperature to ensure the stability and accuracy of the sample.
3. Versatility: Programmed freezers can be applied to different types of samples, including cells, DNA, RNA, proteins, etc. It can also be used to cryopreserve samples or perform operations such as cryopreservation.
4. Safety: The program freezer is reasonably designed, safe and reliable. It is usually equipped with safety protection devices, such as overheating protection and overload protection, to ensure safety during use.

In short, the program freezer is an essential instrument in the laboratory, which can provide rapid freezing and sample protection functions to help biomedical research and experiments.
