Question

what is the principal of centrifugation . thanks for reading.​

Answer 1

Answer:

A centrifuge works by using the principle of sedimentation: Under the influence of gravitational force (g-force), substances separate according to their density. Different types of separation are known, including isopycnic, ultrafiltration, density gradient, phase separation, and pelleting.

$\large{\underline{\underline{\purple{\bf{Cèntrifugation:}}}}}$

• Particles of còlloid can pàss through filter paper, therefore a còlloidal cannot be separated by filtration. However, they get separated by a special technique called Cèntrifugation.
• Cèntrifugation is used to separate cólloidal particles from solution.

$\large{\underline{\underline{\purple{\bf{Centrifuge:}}}}}$

• Cèntrifuge is a device used to separate liquids from solids by spinning.
• Cèntrifugal machine's are cómmonly used for this method.
• The machine can be rótated either by hand, i.e. mànually or elèctrically.

$\large{\underline{\underline{\purple{\bf{Principle:}}}}}$

• This method is basèd on the principle that, the dènser pàrticles are fórced to the bóttom and the lighter pàrticles stay at the top when rótated rapîdly.

$\large{\underline{\underline{\purple{\bf{Applications:}}}}}$

Cèntrifugation technique is used in :

• Diagnóstic labòratories for bloód and urinè tests.
• Washiñg màchines to squèèze out water from wèt clothès.
• Dairies and homes to sèparate butter from cream.
