Centrifuges are essential basic equipment in the research and production processes of modern molecular biology, cytology, clinical medicine, and pharmaceutical industry. With the continuous improvement of scientific research level and the development of the biopharmaceutical industry, the requirements for sample processing in scientific research and production are becoming increasingly strict. It not only requires high speed to ensure separation efficiency, but also requires large capacity and high-precision temperature control to ensure sample quality.
The high-speed floor standing freeze centrifuge (item number: 21M) was born in this context. It integrates multiple advantages such as high speed, low temperature, large capacity, and intelligent control, and is widely used in various fields such as blood product preparation, protein precipitation, virus and subcellular separation, clinical testing, and large-scale experiments in biotechnology. With its outstanding performance and stable quality, this equipment has become an indispensable core equipment in modern laboratories and production workshops.
The separation principle of a centrifuge is to use the strong centrifugal force generated by high-speed rotation to separate substances of different densities and particle sizes in a mixed system. Article number 21M can generate a relative centrifugal force of up to 46140 × g at a maximum speed of 21000 rpm, which is sufficient to achieve effective separation of submicron particles such as viruses, organelles, proteins, and nucleic acids.
At the same time, the equipment is equipped with an efficient fluorine free compressor unit and a dual cycle refrigeration system, which can accurately control the temperature of the centrifugal chamber within the range of -20 ℃ to+40 ℃ during operation, with temperature fluctuations not exceeding ± 1 ℃, ensuring the activity and stability of temperature sensitive samples during centrifugation.
