It is mostly used for separating the solids out of suspensions.
In most suspensions the solid is too fine for filer paper to work correctly.
So it is spin at high speeds, this causes the solid to sink to the bottom of the test tube while the liquid can be decanted off.
A centrifuge is a piece of equipment, generally driven by a motor, that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis. The centrifuge works using the sedimentation principle, where the centripetal acceleration is used to separate substances of greater and lesser density.
A centrifuge is used in a laboratory to separate solids from a suspension. Some precipitates settle very rapidly – such as AgCl. However, some are very slow to settle. The liquid suspension of the precipitate are placed into a centrifuge tube, a special strong glass tube, and this is spun by the centrifuge. The centripital force causes the precipitate to settle at the end of the tube furtherest from the axis of rotation. When the centrfuge is stopped and the tube extracted the precipitae will be found at the bottom of the tube. The clear liquid above the solid can be poured off and the solid recovered.
A centrifuge is often used in industry to concentrate solids from a solution. It is also used in the nucear industry to seperste the various isotopes of uranium

that will ecxplain whate centrifuge is…but i’ve seen it used to settle blood or other suspensions (such as oil and water)
Its not my favourite method of separation…but it does ok
