Typical Specifications

Rotor type

Swing bucket rotor, commonly used for separating samples into distinct layers.

Typical capacity

For this class of rotor, it typically accommodates 4 buckets, each holding multiple tubes (e.g., 50ml, 15ml, or microcentrifuge tubes with adapters).

Maximum RCF (Relative Centrifugal Force)

Units of this type commonly achieve RCFs suitable for general laboratory separations, often in the range of 3,000 to 5,000 x g, depending on the centrifuge model.

Maximum RPM (Revolutions Per Minute)

Typically designed for speeds up to 4,000-5,000 RPM when paired with a compatible centrifuge.

Material construction

Commonly constructed from high-grade aluminium or composite materials for durability and chemical resistance.

Compatibility

This specific rotor is designed for use with compatible Eppendorf centrifuges.

Frequently Asked Questions

• What is a swing bucket rotor used for?

  A swing bucket rotor is used for separating samples into distinct layers or pellets. The buckets swing out horizontally during centrifugation, allowing for flat pellet formation, which is beneficial for density gradient separations and cell harvesting.
