The practical application of centrifuges, what is the centrifuge for

The purpose of the centrifuge is as follows:

1. Separate the solid particles in suspension from the liquid.

2. Separate two liquids with different densities and immiscible liquids in the emulsion (e.g. separating cream from milk).

3. To remove the liquid in the wet solid, the special ultra-speed tube separator can also separate gas mixtures of different densities.

4. Taking advantage of the different sedimentation rates of solid particles of different densities or particle sizes in liquids, some sedimentation centrifuges can also classify solid particles according to density or particle size.

Centrifuge

A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. The centrifugal force is determined by the speed of rotation, the radius of rotation and the melting mass of the substance. Centrifuges are widely used in chemical engineering, petroleum, food processing, pharmaceutical, mineral processing engineering, carbon, water treatment, nuclear energy industry and shipbuilding.

The main principle of the filter centrifuge is to accelerate the liquid phase in the solid-liquid mixture out of the bowl through the centrifugal force generated by the centrifugal drum running at high speed (with appropriate filter media), and leave the solid phase in the bowl to achieve the effect of separating solid and liquid, or commonly known as the effect of dehydration.

The main principle of the sedimentation centrifuge is to accelerate the sedimentation rate of different specific gravity components (solid phase or liquid phase) in the mixture through the strong centrifugal force generated by the high-speed rotation of the rotor, and to separate the substances with different sedimentation coefficients and buoyancy densities in the sample.

When using various centrifuges, the centrifuge tube and its contents must be precisely balanced on the balance in advance, the difference in weight during the balance shall not exceed the range specified in the instructions of each centrifuge, the different rotors of each centrifuge have the allowable difference of each row of hands, the rotor must not be loaded with a singular number of tubes, when the rotor is only partially loaded, the tubes must be placed symmetrically in the rotor so that the load is evenly distributed around the rotor. <

1. When using various centrifuges, the centrifuge tube and its contents must be accurately balanced on the balance in advance, and the difference in weight during the balance shall not exceed the range specified in the instructions of each centrifuge, and the different rotors of each centrifuge have their own allowable differences, and the rotor must not be loaded with a singular number of tubes, when the rotor is only partially loaded, the tubes must be placed symmetrically in the rotor in order to evenly distribute the load around the rotor.

2. If you want to centrifuge at a temperature lower than room temperature. The rotor should be pre-cooled in the refrigerator or in the rotor chamber of a centrifuge before use.

3. Do not leave at will during the centrifugation process, observe whether the instrument on the centrifuge is working normally at any time, and stop the machine immediately for inspection if there is any abnormal sound, and eliminate the fault in time.

4. Each rotor has its own maximum allowable speed and cumulative time limit, and the manual should be consulted when using the rotor, and it should not be used at excessive speed. Each rotor must have a usage file to record the accumulated use time, if the maximum use time limit of the rotor is exceeded, it must be used at a reduced speed according to the regulations.

5. When loading the solution, it should be carried out according to the specific operation instructions of various centrifuges, and the appropriate centrifuge tube should be selected according to the nature and volume of the liquid to be centrifuged.

Summary. Dear, glad to answer for you. At present, the commonly used centrifuges in hospitals are more used in hospitals, and the centrifuge products include blood centrifuges, blood group card centrifuges, urine sediment centrifuges, biopharmaceutical centrifuges, gel bubble treatment centrifuges, etc., with a wide variety and different functions.

The specific application of the centrifuge is the use and function of the medical centrifuge: 1) It is used to separate the particles suspended in the solution 1) to separate the formed components in the blood, concentrate the cells or other formed components in the body fluid, and use them for analysis and determination; 2) Isolate ligands and free ligands that bind to proteins or antibodies. 3) Isolate the proteins that have precipitated in the specimen.

2. Separation of two immiscible liquids with different densities: 1) For example, the use of organic solvents to extract certain components of body fluids. 2) Separation of lipid components in blood, such as separation of chylomicroparticles and various lipoproteins in plasma.

Dear, glad to answer for you. Commonly used centrifuges are currently used in hospitals, and the centrifuge products are blood centrifuges, blood group card centrifuges, urine sediment centrifuges, biopharmaceutical centrifuges, gel bubble treatment centrifuges, etc., which are of a wide variety and have the same functions. The specific application of the Bi leak centrifuge is the use and function of the medical centrifuge:

1) For the separation of particles suspended in solution 1) Separation of formed components in blood, concentrated cells or other formed components in body fluids for analysis and determination; 2) Isolate ligands and free ligands that bind to proteins or antibodies. 3) Isolate the proteins that have precipitated in the specimen. 2. Separation of two immiscible liquids with different densities: 1) For example, the use of organic solvents to extract certain components of body fluids.

2) Separation of lipid components in blood, such as separation of chylomicroparticles and various lipoproteins in plasma.

1. Medical institutions: dear, centrifuges are widely used. 1. Hospital:

Centrifuges are mainly used in the separation of liquid specimens such as blood, urine, and liver ascites. In particular, the centrifuge is a necessary instrument for the laboratory department, and the number of blood specimens in the laboratory department is very large in the tertiary hospital, so the current medical automatic cap centrifuge is very popular with doctors and friends, because the automatic cap removal function of this kind of centrifuge not only saves the trouble of manual hat pulling, but also saves working time and improves work efficiency, and is the first choice for doctors to choose centrifuges. 2. Blood bank of blood bank:

Most of the centrifuges used in blood banks are large-capacity centrifuges, which separate the components of blood in blood bags, separate various components in the blood, and apply the delivery of related components that are delayed by different diseases. Generally, ultra-large capacity refrigerated centrifuges are used. 3. Center for Disease Control and Prevention, Inspection and Quarantine Institutions:

Centrifuges used by disease control and inspection and quarantine institutions are mainly used for testing and separating blood samples, extracting relevant components, and detecting related diseases.
