Desktop high-speed centrifugeIt is a compact laboratory equipment that uses centrifugal force to separate different components in a sample. It is widely used in biomedical, chemical, food science and other fields, suitable for separating small particles such as cells, proteins, nucleic acids, etc. Desktop high-speed centrifuges have become indispensable separation equipment in laboratories due to their small size, high speed, and easy operation. Its working principle is based on the action of centrifugal force. When the centrifuge rotates, the particles in the sample move outward due to centrifugal force, and the centrifugal force they receive is proportional to the mass of the particles, the radius of rotation, and the square of the rotational speed. Due to the different densities and sizes of particles, they also experience different centrifugal forces, thus achieving separation.
Desktop high-speed centrifugeIts application scope is wide, covering multiple fields, as follows:
1、 Biomedical field
