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 ...
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.
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.
Centrifuge: to separate supernatant & pellet Cragie tube: see link: Desiccator: to dry things Durham's tube: used to detect gas production in sugar fermentation media; the tube is placed in an inverted fashion so that gases produced get trapped in it and do not float away to the surface Gas-pak
During a relatively short or slow centrifugation, the particles are separated by size, with larger particles sedimenting farther than smaller ones. Over a long or fast centrifugation, particles travel to locations in the gradient where the density of the medium is the same as that of the particle density; (ρp – ρm) → 0.
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.
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 ...
Rate-zonal centrifugation is a centrifugation technique employed to effectively separate particles of different sizes. [1] The tube is first filled with different concentrations of sucrose or another solute establishing layers with different densities and viscosities , forming a density gradient , within which the particles to be separated are ...
