Study Notes
Centrifuge Basics
- A centrifuge is a device that uses centrifugal force to subject a specimen to a specified constant force.
- Separates various components of a fluid by spinning it at high speed within a container.
Separation Process
- Separates fluids of different densities (e.g. cream from milk) or liquids from solids.
- Denser substances and particles move outward in the radial direction.
- Less dense objects are displaced and moved to the centre.
Laboratory Centrifuge
- Uses sample tubes to separate particles and substances.
- Radial acceleration causes denser particles to settle to the bottom of the tube.
- Low-density substances rise to the top.
Industrial Applications
- Commonly used in manufacturing and waste processing to sediment suspended solids.
- Separates immiscible liquids.
- Example: cream separator in dairies.
Additional Benefits
- Can be a very effective filter, separating contaminants from the main body of fluid.
