A centrifuge is a device that uses centrifugal force to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids. It works by causing denser substances and particles to move outward in the radial direction. At the same time, objects that are less dense are displaced and move to the centre. In a laboratory centrifuge that uses sample tubes, the radial acceleration causes denser particles to settle to the bottom of the tube, while low-density substances rise to the top. A centrifuge can be a very effective filter that separates contaminants from the main body of fluid. Industrial scale centrifuges are commonly used in manufacturing and waste processing to sediment suspended solids, or to separate immiscible liquids. An example is the cream separator found in dairies. Very high speed centrifuges and ultracentrifuges able to provide very high accelerations can separate fine particles down to the nano-scale, and molecules of different masses. Large centrifuges are used to simulate high gravity or acceleration environments (for example, high-G training for test pilots). Medium-sized centrifuges are used in washing machines and at some swimming pools to draw water out of fabrics. Gas centrifuges are used for isotope separation, such as to enrich nuclear fuel for fissile isotopes.
The floor centrifuge has the advantages of beautiful appearance, large capacity, small volume and complete functions. It has the advantages of stable performance, adjustable speed, automatic balance adjustment, low temperature rise, high efficiency and wide applicability. The product is suitable for qualitative analysis of serum, plasma and urea in pharmaceutical products, blood stations, clinical trials and biochemical laboratories. Its principle is to separate and concentrate particles in suspension with different physical properties (such as mass, buoyancy, sedimentation coefficient, etc.) by using strong centrifugal force. It is brushless maintenance free DC motor or AC variable frequency drive. The refrigeratied centrifuge is cooled and temperature controlled by the compressor. The centrifugal precipitation of cells and biological macromolecules is realized by setting the centrifugal rate, centrifugal force, time and temperature. The floor centrifuge adopts brushless motor, module control and stepless speed regulation, which has the advantages of safety, reliability and durability. It is a fast separation equipment selected for biochemical experiments in medical, health, agriculture, forestry and animal husbandry, food, petroleum and other industries.
A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed. It is mainly used in the field of experimental solid-liquid separation, and can also deal with small batch of non experimental solid-liquid separation operations. It uses the centrifugal force generated by the rotating head to separate the substances with different particle sizes and densities in the emulsion or suspension. Laboratory centrifuges are widely used in pharmaceutical, environmental protection, chemical, food, mining, teaching and other laboratories. Due to the small volume of laboratory centrifuges, compared with other industrial centrifuges, the materials used will be much less, so the cost is relatively low. Generally, large and small factories can produce and manufacture, so laboratory centrifuges have good advantages in cost performance in the place where centrifuge enterprises gather.
The haematocrit, is the volume percentage (vol%) of red blood cells (RBCs) in blood, measured as part of a blood test. The measurement depends on the number and size of red blood cells. It is normally 40.7–50.3% for males and 36.1–44.3% for females. It is a part of a person's complete blood count results, along with hemoglobin concentration, white blood cell count and platelet count. Because the purpose of red blood cells is to transfer oxygen from the lungs to body tissues, a blood sample's hematocrit—the red blood cell volume percentage—can become a point of reference of its capability of delivering oxygen. Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions. An abnormally low hematocrit may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally high hematocrit is called polycythemia. Both are potentially life-threatening disorders. Haematocrit centrifuges are used to measure the volume percentage of red blood cells in whole blood.
Bench Top ;Centrifuge is a machine that uses centrifugal force to separate components in liquid and solid particles or liquid and liquid mixture. The Bench Top ;Centrifuge is mainly used to separate the solid particles in the suspension from the liquid; Or separate two liquids in the emulsion with different densities and immiscible with each other (for example, cream is separated from milk); It can also be used to remove liquids from wet solids, such as drying wet clothes with a washing machine; The special overspeed tubular separator can also separate gas mixtures with different densities; Taking advantage of the different settling velocity of solid particles with different density or particle size in liquid, some settling bench centrifuges can also classify solid particles according to density or particle size. It can be used in medical fields, such as hospitals, centers for Disease Control and prevention, blood centers, animal husbandry and aquatic products, and radioimmunoassay; Research fields such as colleges and universities, research institutes, R & D centers, laboratories (which can be used for the separation of subcellular organelles, proteins, viruses and other samples), etc.
Crude oil centrifuge is designed for the determination of water and sediment in crude oil (centrifugal method) and manufactured according to the requirements of GB / t6533-86 standard. It uses centrifugal separation to determine water and sediment in crude oil. It is an ideal separation equipment for water determination in oil exploitation industry and scientific research institutions. It uses large screen liquid crystal display (LCD) and digital tube display (LED) (purchased by customers), which can display rotor number, speed, time, temperature, centrifugal force, addition and subtraction rate and fault information. The annular heater is adopted, which can heat quickly and evenly, and has the functions of temperature control and constant temperature, so as to meet the requirements of the oil industry for the temperature of the "host". In addition, the strong rectangular frequency conversion motor is adopted, which has stable and fast lifting speed, long service life, no daily maintenance and low noise, which greatly improves the stability of the instrument. The centrifugal tube is made by special process, and the glass centrifugal tube will not break during operation. The centrifugal pipe has been widely used in Daqing Oilfield. It is equipped with fault self diagnosis system, which can automatically detect overspeed, overtemperature, imbalance, door cover self-locking and other faults, and display fault information in the display window to improve the safety performance of the instrument.
