What Is A Low-speed Centrifuge?

Mar. 13, 2024



Low-speed centrifuge is a commonly used clinical testing equipment, used to separate and precipitate solid particles or cells in liquids. It separates the sample into different layers by rotating centrifugal force, thereby facilitating subsequent experimental operations. Low-speed centrifuges are characterized by lower rotational speeds, usually between 1000-5000 rpm, which can avoid sample damage and loss. At the same time, it has the advantages of small size, low noise, and easy operation, and is suitable for daily work in clinical laboratories and scientific research units.


The low-speed centrifuge consists of a host machine, a rotor and a control system. The host is the core component of the centrifuge, responsible for providing power and controlling the speed. The rotor is the rotating part of a centrifuge that holds sample tubes or centrifuge tubes. The control system can adjust the speed and time of the centrifuge to meet the needs of different experiments.


Low-speed centrifuges can be divided into various types according to different application requirements. Common types include desktop centrifuges, desktop refrigerated centrifuges, desktop high-speed centrifuges, etc. The desktop centrifuge is suitable for conventional centrifugal separation operations; the desktop refrigerated centrifuge can perform centrifugation operations at low temperatures and is suitable for experiments that require higher sample temperature; the desktop high-speed centrifuge can reach higher speeds and is suitable for centrifugation speed More demanding experiments.



1.Separate blood components: A low-speed centrifuge can separate blood samples into plasma and red blood cells. By rotating the centrifuge rotor, the centrifuge can generate high-speed centrifugal force, causing red blood cells to settle at the bottom of the centrifuge tube and plasma to float to the top of the centrifuge tube.


2.Separate urine components: A low-speed centrifuge can separate urine samples into supernatant and sediment. Solid components in urine, such as cells, bacteria, crystals, etc., will precipitate to the bottom of the centrifuge tube during the centrifugation process, while the supernatant will float to the top of the centrifuge tube.


3.Separation of cells and organelles: Low-speed centrifuge can be used to separate cells and organelles. By adjusting the speed of the centrifuge and the angle of the centrifuge tube, cells and organelles can be separated. This is very important for cytological studies and cell analysis.


4. Separation of bacteria and viruses: Low-speed centrifuge can be used to separate bacteria and viruses. Through the centrifugation process, bacteria and viruses can be separated from the sample to facilitate subsequent research and analysis.


5.Separation of other solid components: Low-speed centrifuges can also be used to separate other solid components, such as cell debris, protein precipitation, etc. This is very important for biochemical research and analysis.



Clinical application


Low-speed centrifuge is a common clinical testing instrument and is widely used in laboratories of medical institutions. It uses the principle of centrifugation to separate solid components from liquids in liquid samples, thereby helping doctors conduct various clinical tests. Low-speed centrifuges have a variety of uses in clinical applications.


First, it can be used for blood separation. In clinical examinations, doctors need to conduct various tests on blood samples, such as blood cell count, blood type identification, etc. A low-speed centrifuge can separate blood samples into plasma and red blood cells, making it easier for doctors to conduct subsequent testing. Secondly, low-speed centrifuges can also be used for urinalysis. Urine contains various metabolites and waste products. Through centrifugal separation, the urine supernatant can be obtained, which can be used to detect various components in urine, such as protein, sugar, etc. In addition, low-speed centrifuges can also be used for body fluid analysis. Body fluids include ascites, pleural effusion, etc. Through centrifugation, the supernatant can be obtained, which can be used to detect the cells, proteins and other components in it to help doctors determine the type and severity of the disease.





1.Before using the low-speed centrifuge, you must carefully read and understand the instruction manual and operate it correctly in accordance with the instructions.


2.When operating a low-speed centrifuge, appropriate personal protective equipment, such as gloves, goggles, etc., should be worn to prevent accidental injury.


3.Before using the low-speed centrifuge, you should check whether the appearance of the centrifuge is intact and whether there are any damaged or loose parts. If there are any problems, they should be repaired or replaced in time.


4.When operating a low-speed centrifuge, ensure that the base of the centrifuge is stable to prevent vibration or tipping.


5.When placing sample tubes or centrifuge tubes, make sure the tube caps are tight to prevent sample leakage during centrifugation.


6.When using a low-speed centrifuge, the appropriate centrifugation speed and time should be selected according to the characteristics and requirements of the sample.


7.During the centrifugation process, the surrounding environment of the centrifuge should be kept clean to prevent dust or impurities from entering the inside of the centrifuge.


8.After centrifugation, stop the centrifuge and wait for the centrifuge to stop completely before opening the centrifuge cover and taking out the sample.


9.Maintenance of the centrifuge should be carried out regularly, including cleaning the inside and outside of the centrifuge, and checking whether the power cord and plug are normal to ensure the normal operation of the centrifuge.
