Types of Benchtop Centrifuges:

Fixed-angle centrifuge: Ideal for pelleting or separating dense particles, with a fixed rotor angle of approximately 45 degrees.

Swing-out centrifuge: Features a rotor that swings outward during operation, suitable for separating components with varying densities or collecting samples from tube bottoms.

Microcentrifuge: Compact units designed for small volume samples in microcentrifuge tubes, commonly used in molecular biology and biochemistry.

Refrigerated benchtop centrifuge: Equipped with cooling systems to maintain low temperatures during operation, crucial for temperature-sensitive samples.

High-speed benchtop centrifuge: Designed to achieve very high rotational speeds, above 10,000 rpm, for efficient separation and pelleting.

Principle of Benchtop Centrifuges:

Benchtop centrifuges utilize centrifugal force generated by high-speed rotation to separate and sediment particles in a sample. Heavier particles migrate outward, while lighter components remain closer to the center, enabling isolation and analysis.

Parts of Benchtop Centrifuges:

Rotor: Holds sample tubes or containers and rotates at high speeds.

Motor: Drives rotor rotation and controls speed and duration.

Control Panel: Allows setting and adjustment of parameters like speed, time, and temperature.

Lid and Safety Features: Ensures safe operation with lid-locking mechanisms and rotor imbalance detection.

Display: Provides real-time information on centrifuge parameters.

Centrifuge Tubes or Carriers: Hold samples during centrifugation.

Cooling System (in refrigerated centrifuges): Maintains low temperatures for sensitive samples.
