In modern life sciences, medical research, and the pharmaceutical industry, sample separation and preparation are key steps in experimental and production processes. With the continuous improvement of scientific research level and the increasing demand of industry, traditional small capacity, single function centrifugal equipment is gradually unable to meet the needs of large-scale, long-term, high-precision separation. Therefore, floor standing cryogenic centrifuges with high-speed performance, large capacity processing capabilities, and stable temperature control systems have gradually become indispensable core equipment for research institutes, hospital laboratories, and biopharmaceutical companies.
The high-speed and large capacity cryogenic centrifuge (item number: 7M) was born in this context. It not only reaches the international advanced level in terms of speed, capacity, temperature control accuracy, but also balances safety and intelligence, suitable for various scenarios such as blood product production, protein precipitation, cell separation, vaccine preparation, etc.
The basic principle of a centrifuge is to use the centrifugal force generated by high-speed rotation to separate components of different densities. Item number 7M adopts a brushless variable frequency motor direct drive rotor, which can generate a centrifugal force of over 14000 × g when rotating at high speed, allowing samples such as blood, proteins, and cells to quickly separate or precipitate in a short period of time.
In addition, the device is equipped with a refrigeration system that can control the temperature of the centrifuge chamber within the range of -20 ℃ to+40 ℃ during operation, ensuring the activity and stability of temperature sensitive biological samples. Combined with the pre cooling function, the chamber can be cooled down to the required experimental environment in a short period of time.
