The churning of butter from cream is the best example to illustrate centrifugation. A simple device called centrifuge is used to rapidly churn cream which emulsifies over a period of time (depending on its volume) to form butter. The earliest centrifuge was simply a wooden spindle with an extended handle. Centrifuges have, over the years, evolved into more than simple spindled instruments and find application in laboratories, medicine and industries today.
A laboratory centrifuge is adopted to separate suspended particles from a medium. An ultra-sensitive lab centrifuge can be employed in case of organic suspensions, particularly those that contain living matter like bio-molecules. Industrial centrifuge application ranges from simple chemical isolation to sorting molecules of isotopes, the technology backing which is of utmost importance in designing anti-nuclear shields. A home centrifuge could involve simple application in the kitchen and surprisingly enough, a dryer employed to dry wet clothes is also a centrifuge.
Centrifuges are essential in every manufacturing and research unit to obtain pure samples of a substance. The process of procuring test samples would otherwise have to employ complex processes which are uneconomical as they require immense financial investment. It is therefore a great idea for all manufacturing sectors to invest on a centrifuge after through scanning of its application to help cut cost while maintaining a competitive test process.
