Centrifuge is a widely used equipment in many fields, and there are many interesting facts behind it. This article tells some interesting facts about centrifuge:
Interesting story of development history
Origin and early development:
The predecessor of the centrifuge originated from the rotating arm device of British military engineers in the 18th century, which was used to determine resistance. With the advancement of technology, the centrifuge gradually developed from low speed to high speed, and its functions and application range continued to expand. A major breakthrough in technology, the development of the centrifuge has paved the way for enhanced efficiency and accuracy in testing methods. With speeds increasing dramatically from its early origins, this tool has found a place in various industries, and has become essential for obtaining precise measurements and data analysis.
Milestone:
In 1878, Gustaf de Laval of Sweden invented the first cream separator that could separate cream from milk, with a speed of 3,000 r/min. This invention marked the initial application of centrifuges in the food industry.

In 1924, Swedish chemists Svedberg and Rinde created the first oil-turbine ultra-high-speed centrifuge with an optical system and a rotation speed of 45,000 rpm. This innovation revolutionized biochemical research and earned Svedberg the Nobel Prize in Chemistry.
The secret of the working principle
The role of centrifugal force:
The centrifuge separates the different components in the mixture through the centrifugal force generated by rotation. This force causes particles or molecules of different densities or sizes to move to different positions under the action of centrifugal force, thereby achieving separation. With the powerful force of centrifugation, this efficient machine separates various components of mixtures by utilizing rotational energy. This breakthrough technology allows particles and molecules of varying densities or sizes to be sorted into distinct layers, enabling unparalleled separation capabilities.
Precise control:
Precise control: The separation effect of the centrifuge is affected by many factors, such as speed, time, sample volume, and centrifuge tube design. By precisely controlling these factors, the separation efficiency and purity can be improved. Optimize your centrifuge separation with precision. By controlling factors like speed, time, sample volume, and tube design, maximum efficiency and purity is achievable.
Widely used fields

Centrifuges play an important role in biomedical research and are often used to separate biological macromolecules such as DNA, RNA, and proteins, as well as organelles, cell fragments, etc. In biological sample separation experiments such as DNA extraction, the performance technical indicators and correct use of the centrifuge are crucial, especially temperature control plays a key role in maintaining the integrity of DNA molecules. A crucial tool in biomedical research, centrifuges are capable of efficiently extracting DNA, RNA, proteins, and other biological molecules from samples. Temperature control is imperative to maintain the integrity of DNA molecules, making correct usage and performance technical indicators key for successful experiments.
Industrial production:
Centrifuges are also widely used in the pharmaceutical, chemical, and food industries. For example, in the pharmaceutical industry, centrifuges are used to separate drug components and purify them; in the petrochemical industry, centrifuges can be used for oil-water separation and catalyst recovery.
Environmental Protection and Wastewater Treatment:
Centrifuges are important equipment in the field of environmental protection and wastewater treatment. They separate sediments and impurities, liquids and solids in water through high-speed rotation, thereby removing pollutants from water.
Innovation and Development
Technological innovation:
With the continuous advancement of science and technology, the design and manufacturing technology of centrifuges are also constantly innovating. For example, modern centrifuges may be equipped with precise temperature control systems, sample temperature compensation functions, etc. to meet the strict requirements for temperature control during the separation process.
Market demand:
With the increase in market demand, the application scenarios of centrifuges will continue to expand and optimize. For example, in beauty and dental hospitals, centrifuges are often used for separation of PRP (platelet-rich plasma), PRE (platelet-rich fibrin), CGF (concentrated growth factor), etc.
