Centrifuges are lab workhorses that add exceptional functionality and efficiency to your lab. Centrifuge rotors are critical components of these machines that help the device separate particles or substances for various densities in solutions. The rotor creates a centrifugal force through high-speed spinning to separate particles efficiently for biology, pharmaceuticals, clinical research and chemistry to help separate proteins, purify samples or isolate DNA.

Centrifuge rotors are pivotal in processing samples, advancing scientific discoveries and conducting analyses. They are indispensable in research and scientific laboratory work.

Features of Centrifuge Rotors

Rotors are manufactured to suit various applications, enabling scientists and researchers to get accurate sample processing and separation results. View how the choices you make affect how well-suited your centrifuge will be for your laboratory's workflows.

Rotor Types

There are three primary types of centrifuge rotors, each tailored to specific laboratory applications:

  • Fixed-angle: These rotors hold tubes at a fixed angle between 25 and 40 degrees. The high centrifugal forces these rotors facilitate make them ideal for pelleting particles or solids. Fixed-angle rotors are often used in DNA or RNA isolation or to separate cellular components. 

  • Swinging bucket: For low-speed, high-volume separation, swinging bucket rotors are the right choice. They suspend multiple sample tubes in buckets, turning outward as the centrifugal force increases and gently handling samples to isolate softer components or harvest cells without unsettling fragile structures. This rotor type offers longer centrifugation times and is suited for cell and tissue cultures.

  • Vertical tube: These instruments hold tubes in a vertical position, perpendicular to the rotor axis. They have short run times, making them apt for density gradient separations. These rotors are ideal for purifying organelles, separating subcellular components and isolating viruses. 

Material Composition

The best material composition for your centrifuge's rotor depends on your lab's applications. These devices are made from durable materials with high corrosion resistance and can withstand high speeds. Some of the most commonly used materials are:

  • Aluminum: Due to this material's lightweight nature, rotors made from aluminum may have some speed limitations.

  • Carbon fiber: Offering exceptional strength and fatigue resistance and capable of handling high speeds, carbon fiber construction reduces fatigue-related challenges and the risk of rotor failure.

  • Titanium: This material offers superior strength and an increased ability to withstand harsh chemical environments and high speeds, making Titanium rotors ideal for specialized applications that require especially durable equipment.

Capacity and Speed Considerations

Different rotors offer various speeds and capacities to accommodate multiple sample tube volumes. Many rotors also provide maximum rates and relative centrifugal forces (RCF) to allow for precise separations in a range of particle sizes or sample densities. Typical speeds are between 21,999 rpm and 30,000 rpm.

Swinging Bucket Versus Fixed-Angle Rotor

The choice between a swinging bucket and fixed-angle rotor depends on your application. Swinging bucket rotors are best for applications like separating compounds with varying densities or sedimentation rates, which require a gentle separation. The horizontal positioning in this device minimizes the sheer force compounds are exposed to, which also assists in cell harvesting. Fixed-angle rotors work well for pelleting solids or particles at the bottom of a test tube because their angular design supports tight pellet formation in more dense components.

Benefits of Buying Used Centrifuge Rotors

It is important to choose a rotor that suits your budget and application. Buying a used centrifuge rotor has three primary advantages:

  • Cost-effectiveness: Used centrifuge rotors offer a budget-friendly option that does not compromise performance. Buying used laboratory equipment from New Life Scientific provides quality instruments at 30% to 70% off retail prices.

  • Quality and parametric optimization: Pre-tested, certified and calibrated to ensure you get the most out of your used centrifuge rotor.

  • Sustainability aspect: New Life Scientific is committed to sustainability through a circular economy. By extending lab instruments' remaining service life, we keep them from being added to landfills and reduce the materials needed for manufacturing new devices.

What to Look for in Used Centrifuge Rotors

When shopping for a used microcentrifuge with a rotor, it is crucial to assess several characteristics:

  • Durability: The rotor must be able to withstand long-term use. Assess wear and tear, such as corrosion and cracks, and validate the proper functioning of safety features on the device.

  • Speed and weight: Rotors range from 1,500 to 28,000 revolutions per minute (rpm) at top speeds. Check the smoothness of rotor movement, ensuring the rotor is robust enough to withstand these high speeds.

  • Verification: Ensure you receive the rotor's certification and pre-testing information.

  • Application: Verify that the centrifuge rotor you want to buy aligns with the type of centrifuge you use in the lab.
