Collection: Ultracentrifuges
Ultracentrifuges for Sale - New and Refurbished | mLab Supply
Ultracentrifuges operate at speeds above 50,000 RPM and generate forces exceeding 100,000 x g for subcellular fractionation, density gradient separations, and macromolecular pelleting. mLab Supply sources new, refurbished, and surplus preparative and analytical ultracentrifuges from leading manufacturers.
Related Centrifuge Equipment
- Centrifuges - General-purpose benchtop and floor-standing centrifuges
- Refrigerated Centrifuges - Temperature-controlled centrifugation for sensitive samples
- Microcentrifuges - High-speed microcentrifuges for 0.5-2.0 mL tubes
Common Use Cases
- Subcellular fractionation and organelle isolation
- Density gradient separations (sucrose, CsCl, iodixanol)
- Virus and viral vector purification and concentration
- Lipoprotein and exosome isolation
- Macromolecular pelleting of ribosomes and large protein complexes
What to Look For
- Maximum speed and RCF: Confirm the speed and g-force required for your application - exosome isolation typically requires 100,000-200,000 x g
- Rotor compatibility: Confirm availability of swinging bucket, fixed angle, and vertical rotors for your tube sizes and volumes
- Refrigeration: All preparative ultracentrifuges include refrigeration - confirm temperature range and stability
- Rotor certification: Rotors have defined run-hour limits - confirm rotor age and certification status before purchase
