Density gradients for purifying cells are also run in these centrifuges. Swinging-bucket rotors tend to be used very widely because of the huge flexibility of sample size through the use of adaptors. [9] These machines have maximum rotor speeds of less than 10 000 rpm and vary from small, bench-top to large, floor-standing centrifuges. [11]
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.
A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed. There are various types of centrifuges, depending on the size and the sample capacity.
[1] Peeler centrifuge operates on the principle of centrifugal force to separate solids from liquids by density difference. And high rotation speed provides high centrifugal force that allows the suspended solid in feed to settle on the inner surface of drum, also washing and washing processes at the same rotational speed and in same centrifuge vessel.
During the separation, the cell only needs to be suspended in a buffer solution and enter a centrifuge, the whole processes does not involve any chemical (e.g. staining) and physical (e.g. attachment of antibody, lyses of cell membrane) effect on the cells, so the cell will remain unchanged before and after the separation. Because of this, the ...
The Oxford Textbook of Medicine [1] is an international textbook of medicine.First published in 1983, it is now in its sixth edition. [2] It is primarily aimed at mature physicians looking for information outside their area of particular expertise, but widely used as a reference source by medical students and doctors in training, and by others seeking authoritative accounts of the science and ...
A cytocentrifuge, sometimes referred to as a cytospin, [1] is a specialized centrifuge used to concentrate cells in fluid specimens onto a microscope slide so that they can be stained and examined. [2] Cytocentrifuges are used in various areas of the clinical laboratory, such as cytopathology, hematology and microbiology, as well as in ...
An ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1 000 000 g (approx. 9 800 km/s²). [1] There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge.
