Functions and Application Areas of Low-speed Centrifuges

Low-speed centrifuge refers to a centrifuge with a rotation speed of less than 10,000 rpm. It is widely used in clinical medicine, biochemistry, immunology, blood bank and other fields. It is a conventional instrument for centrifugal sedimentation in laboratories. Then, let's learn about the functions and application fields of low-speed centrifuges and precautions for use!


The low-speed centrifuge separation technology is a new technology developed on the basis of the particle state in the practical centrifugal field. Particles of different densities, sizes, or shapes settle in the centrifugal field at different speeds, so that a roughly spherical inhomogeneous mixture can be separated by centrifugation.


Tabletop low-speed centrifuges are designed to further study biochemistry and separate large quantities of substances. For example, they can be used to harvest cells, isolate plasma, separate DNA and protein molecules from these prepurified preparations, separate viruses as well as large-scale Escherichia coli, stringent cellular components, nucleoprotein particles, etc.


Cence tabletop low-speed centrifuges, which are with low noise, convenient operation, safety and reliability, are widely used in experiments and scientific research in the fields of biology, chemistry, medicine, agriculture and forestry, food safety, blood bank, clinical trials, etc., and qualitative analysis of serum, plasma, urine, etc.


Clinical benchtop centrifuge is widely used in the medical field. The separation and research of cells and DNA molecules at the microscopic level requires high-speed medical centrifuges. The rotational speed of this high-speed centrifuge is usually above 5,000 rpm and below 60,000 rpm, which can provide centrifugal force 10,000 times the acceleration of gravity to separate small molecules.


Blood separation generally uses a 3000rpm low-speed centrifuge, which can be produced by most manufacturers at present, and has achieved good results in practical use. The centrifuge used in the refining process such as drug refining is a general low-speed centrifuge, the speed is below 3000 rpm, and the processing capacity is large. In order to meet the GMP standards and requirements in drug production, it is generally made of stainless steel.


The function of the low-speed centrifuge: the intelligent electric centrifuge rotates at a certain speed to generate centrifugal force, and the liquid test material in the centrifuge tube is separated and precipitated according to the size of the particles and the mass under the action of the centrifugal force, and the test is carried out. Electric centrifuges are commonly used for bacterial sedimentation, serum separation, red blood cell washing, and other materials with different specific gravity.
