Centrifuge
A centrifuge is a device for rotating the liquid specimen at high speed to separate them into two phases. With the rotation, the liquid specimen with the heavier mass will collect at the bottom, also known as the pellet section. Other parts with lighter mass will be on top, also known as supernatant. To get good tool accuracy and to maintain the Centrifuge quality used in laboratories or industries, it is necessary to calibrate periodically by measuring the speed per minute and time.
