Droplet Centrifuge Machine Microcentrifuges Blue Color With Material Copper have been used for numerous scientific applications in laboratories around the world. Centrifuges are often used to separate substances based on their density, a process called density gradient separation. This is done because substances such as proteins will move from an area of high concentration to an area of low concentration, a process known as osmosis.This is very important in many scientific fields such as medicine and genetics, where samples may need to be separated based on their density.
