Non-Human centrifuge. At the European Space Agency (ESA) technology center ESTEC (in Noordwijk, the Netherlands), an 8-metre (26 ft) diameter centrifuge is used to expose samples in fields of life sciences as well as physical sciences. This Large Diameter Centrifuge (LDC) [20] began operation in 2007. Samples can be exposed to a maximum of 20 ...
The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
ISS Centrifuge Demo: a 2011 NASA proposal for a demonstration project preparatory to the final design of the larger torus centrifuge space habitat for the Multi-Mission Space Exploration Vehicle. The structure would have an outside diameter of 30 feet (9.1 m) with a ring interior cross-section diameter of 30 inches (760 mm).
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]
Centrifuges are used in science and industry to separate substances. In the reference frame spinning with the centrifuge, the centrifugal force induces a hydrostatic pressure gradient in fluid-filled tubes oriented perpendicular to the axis of rotation, giving rise to large buoyant forces which push low-density particles inward. Elements or ...
Hypergravity is defined as the condition where the force of gravity (real or perceived) exceeds that on the surface of the Earth. [1] This is expressed as being greater than 1 g . Hypergravity conditions are created on Earth for research on human physiology in aerial combat and space flight, as well as testing of materials and equipment for ...
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.
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 ...
