Principles of Super Centrifuge
The super centrifuge, also known as an ultracentrifuge, operates on the principle of generating extremely high centrifugal forces to separate particles based on very small differences in density.
These centrifuges can achieve speeds much higher than conventional centrifuges, enabling the separation of sub-micron particles and molecules.
Construction
Rotor/Bowl: A high-strength rotor that can withstand extremely high speeds.
Drive System: A powerful motor and spindle designed for ultra-high-speed rotation.
Vacuum System: Often includes a vacuum chamber to reduce air resistance and heating due to friction.
Cooling System: Maintains temperature control to prevent overheating during high-speed operation.
Control System: Advanced control panel for precise adjustment of speed, temperature, and other parameters.
Safety Enclosure: A robust housing to contain the rotor and ensure safety during operation
Working
Loading: The sample is loaded into the rotor or sample tubes, which are then placed in the centrifuge.
Acceleration: The centrifuge accelerates to ultra-high speeds, generating enormous centrifugal forces.
Separation: Particles are separated based on density differences, with denser particles moving to the outer edge of the rotor and lighter particles staying closer to the center.
Deceleration: The centrifuge decelerates after the desired separation is achieved, and the separated components are collected.
