Centrifuge For the Christian camp, see Centrifuge (camps). For spin direction in quantum mechanics, see Spin (physics) § Spin direction. A laboratory tabletop centrifuge. The rotating unit, called the rotor, has fixed holes drilled at an angle (to the vertical), visible inside the smooth silver rim. Sample tubes are placed in these slots and the motor is spun.

Centrifuge A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis, applying a potentially strong force perpendicular to the axis of spin. The centrifuge works using the sedimentation principle, where the centrifugal acceleration causes 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 center. In a laboratory centrifuge that uses sample tubes, the radial acceleration causes de

Why do labs put blood in tubes and spin them around? Best Answer: Those spinning devices are called centrifuges, and they are used to separate the blood into its component parts so that tests can be performed on that component alone. The denser materials (like red blood cells) sink to the bottom, while the lighter ones (like plasma) float to the top.

Comments: Centrifugal Force vs Centripetal Force Centrifugal force (Latin for 'center fleeing') describes the tendency of an object following a curved path to fly outwards, away from the center of the curve. It's not really a force; it results from inertia — the tendency of an object to resist any change in its state of rest or motion. Centripetal force is a real force that counteracts the centrifugal force and prevents the object from flying out, keeping it moving instead with a uniform speed along a circular path.

Impeller (Coin for comparison, diameter 16.25 mm.). An impeller is a rotating component of a centrifugal pump, usually made of iron, steel, bronze, brass, aluminium or plastic, which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation.

centrifugal The definition of centrifugal is something that is moving, or that is prone to move, away from a center. A force that tends to move away from the center is an example of something that would be described as centrifugal. moving or tending to move away from a center. using or acted on by centrifugal force.

Centrifugal pump Warman centrifugal pump in a coal preparation plant application. Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor.

Centrifuges A centrifuge is simply a machine that spins around to make a large and useful force. Small centrifuges are used in scientific laboratories (for example, to separate blood products). You can find much bigger ones in aerospace-labs, where they're used for testing astronauts, pilots, and their equipment to absolute breaking point.

- The Force exerted on a sample in a centrifuge is a function of the rotation speed of the centrifuge (RPM) and the radius of the rotor. If you know the RPM, the equations to calculate G-Force are: In Centimeters: RCF or G-Force = 0.00001118 x Rotor Radius x (RPM)². OR. In Inches: RCF or G-Force = 0.0000284 x Rotor Radius x (RPM)²
