¶¶ Centrifuge ¶¶
Definition of Centrifuge
A centrifuge is a device by which suspension of solid material in liquid phase is rotated at high speed .
This excellent read the sedimentation process by using of centrifugal force as a result the solid phase separate out and from the sediment at the bottom and the the liquid form the suspentant at the top.
Centrifuge are two types
(1)Hand centrifuge
(2)electric centrifuge
(1)Hand centrifuge
The hand centrifugal are handed drive centrifuge which can reached up to 2000 to 2,500 rotation per minute RPM.
The hand centrifugal can only two to 4 centrifuge tubes which are of 15 ml capacity and usually made of aluminium.
(2)Electric centrifuge
the electric centrifugal are the motor drive centrifuge operated through meins electric supply. these can reach up to 3,500 RPM and they are usually provided with multistage speed regulator to obtain desire Speed the common laboratory centrifuge is used for suspension of serum participate and sediments of variant body fluids urine sediment for microscope examination.
the tube in the centrifugal must be balance exactly otherwise that you will break due to vibration increase or decrease the speed of centrifugal granular the tube must of the same size and weight.
