The centrifuge has now become an indispensable equipment in many fields. The washing machine used in our lives is actually a kind of centrifuge. So, do you know the origin of the centrifuge? The following Centrifuge Suppliers will share with you the development history of centrifuges
The predecessor of the Centrifuge originated in the 18th century when British military engineers invented a rotating arm device for determining resistance.
In 1836, Germany invented the first three-foot centrifuge. In 1878, Gustaf de Laval of Sweden invented the first milk fat separator that can separate butter from milk, with a speed of 3000r/min. Later, the rotation speed of the centrifuge gradually developed from low speed to high speed, and the manufacturing technology was also advancing with each passing day, and it was widely used.
In 1924, Swedish chemists manufactured the world's first oil turbine ultra-high-speed centrifuge with an optical system speed of 45,000 rpm. Later, Theodor Svedberg improved the ultracentrifuge so that the maximum speed could reach 75000 r/min. Using this ultracentrifuge, hemoglobin was separated from blood for the first time, opening a new chapter in biochemical research. Svedberg won the Nobel Prize in Chemistry in 1926 for inventing the ultracentrifuge and using it for the research of highly dispersed colloidal substances.
In 1950, EWiedeman of Switzerland produced a centrifuge directly driven by a variable-frequency motor to further simplify its structure; in the late 1970s, Beckman of the United States introduced a variable-frequency motor directly driven ultracentrifuge.
my country began to develop laboratory centrifuges in 1958. In 1975, the Chinese Academy of Sciences first successfully developed a domestically-made ultracentrifuge. Through the unremitting efforts of several generations of scientists, my country has achieved innovative results comparable to the international first-class level in the field of laboratory centrifuges and ultra-high-speed centrifuges, breaking foreign monopolies.
Developed to the present, many types of centrifuges have been designed according to different separation requirements and structures in practical applications, such as:
Settling centrifuges are mainly used to purify suspensions. Common types are: pendulum centrifuge, separator centrifuge, tube centrifuge.
Filter centrifuges, common ones are: screen/rolling centrifuges, push centrifuges, reverse filter centrifuges, pendulum centrifuges.
Gas centrifuge for isotopic separation.
Others: such as large centrifuges, used to simulate high gravity or acceleration environments. Medium-sized centrifuges are used in washing machines and some swimming pools, to wring out water in fabrics, etc.
