Centripetal acceleration is the force inwards on an object moving in a circular motion.
A centrifuge uses an acceleration (in terms of g, which is the acceleration due to gravity) that is specified by the user. A centrifuge uses 2 rotors at the same rotational speed but with different diameters to create 2 different accelerations.
Particles of different masses will separate in the centrifuge because they move at different speeds due to acceleration.
A centrifuge works by spinning very fast. The centrifugal forces cause the heavier or denser substances to preferentially settle first. The layers which are the least dense will thus be at the top.
The underlying principle of the centrifuge is the sedimentation principle. Basically, centripetal acceleration causes denser substances to separate to the bottom of the tube.
as it spins, centrifugal force causes the most dense/heavier material to go to the outside (bottom of centrifuge tube).
No you do not centrifuge blood for a CBC. This could cause issues when reading the results.

Balance.
Small cylinders of liquids are placed in a disk, with their length in the plane of the disk. When the disk is spun at high revolutions per minute, a high centripetal force, equivalent to several gravities is generated along the length of the tube, thus settling out any heavier portions of the contents. In practice, the tube is inclined to the spin axis, to aid the sediment to flow down the surface of the tube.
That sounds like density centrifugation...So, a centrifuge?
A centrifuge has holes to insert the centrifuge tubes in, a cap to secure the tubes inside, and a lid to protect both the samples and experimenter in case of malfunction. There is also typically a way to set the centrifuge speed and a power switch to turn the centrifuge on and off.
The tube is not so important . It's the centrifuge that does the work.
Antonin Prandtl, however Gustof de Laval invented the first "Modern" centrifuge. http://en.wikipedia.org/wiki/Centrifuge
centrifuge is a system which is used to separate the water from the diesel.
Using centrifuge: brill idea
A Centrifuge Swing-out Rotor is a part of a centrifuge which attaches to the motor and holds the sample tubes. A swing-out, as opposed to a Fixed Angle rotor, has holders that move from vertical to horizontal as the centrifuge speeds up.
A centrifuge is used for separating components in a liquid that have different weights.
During the centrifuge based on their size/ molecular weight it will be separated.
A good centrifuge, such as the Eppendorf 5702 Series, will cost you upwards of $2,000.
outward, because centrifuge means separating.
No. A machine called a centrifuge is used in separation by density.
