Technical Analysis of Freeze Centrifuges in Market Applications

　　As an important laboratory instrument, the refrigerated centrifuge combines centrifugal force with a low-temperature environment to achieve efficient separation and purification of samples in fields such as biology, medicine, chemistry, and food science.

　　Working Principle and Technical Features

　　The basic operating principle of a refrigerated centrifuge is to use an electric motor to drive a compressor, which draws in a low-temperature, low-pressure working fluid gas (such as ammonia or a refrigerant) into the centrifuge. After compression, this gas is released into a separation chamber. In the separation chamber, under the influence of centrifugal force, the liquid components in the gas are separated from the gas itself, thereby achieving sample separation and purification. At the same time, the refrigerated centrifuge is equipped with a low-temperature protection system that maintains a low-temperature environment throughout the centrifugation process, effectively preventing sample denaturation and degradation.

　　 High-speed rotation A refrigerated centrifuge can rotate at high speeds ranging from tens of thousands to hundreds of thousands of revolutions per minute, generating powerful centrifugal forces that rapidly sediment molecules or particles in the sample to the bottom of the tube, thereby achieving efficient separation and enrichment.

　　 Low-temperature protection A refrigerated centrifuge equipped with a low-temperature protection system can maintain the sample at a low temperature throughout the centrifugation process, effectively preserving the sample’s integrity and activity. It is particularly well-suited for experiments that require maintaining the integrity of biological samples.

　　 High precision and high stability The rotating components of the refrigerated centrifuge are meticulously designed and balanced, with precisely controllable rotation speeds that enable high-precision separation and enrichment. At the same time, their exceptional stability ensures reliable performance during prolonged, continuous operation.

　　 Versatility Freeze centrifuges typically offer a variety of centrifugation modes and multiple rotor options, allowing them to be adjusted and adapted to meet diverse experimental needs.
