Ultracentrifuges

Ultracentrifuges are advanced, high-speed centrifugation systems engineered to separate particles of extremely small size and close density, making them critical tools in genomics, proteomics, virology, structural biology, biopharmaceutical research, and nanotechnology. These powerful instruments reach speeds above 100,000 RPM and generate centrifugal forces greater than 600,000 × g, allowing researchers to perform highly precise separations that are not possible with standard centrifuges. Ultracentrifuges are primarily used for subcellular fractionation, exosome isolation, nanoparticle separation, and density gradient centrifugation. Researchers frequently use them to isolate organelles (e.g., mitochondria, nuclei), ribosomes, lipoproteins, viruses, and protein complexes for further analysis. In pharmaceutical and vaccine development, ultracentrifuges are indispensable for purifying viral vectors, formulating lipid nanoparticles (LNPs), and separating complex biomolecular assemblies. These instruments are typically equipped with vacuum systems to minimize friction and heat, ensuring high-speed stability and preserving sample integrity. Models often feature refrigeration, programmable acceleration/deceleration profiles, vacuum monitoring, and rotor recognition to enhance safety and consistency. Both fixed-angle and swinging-bucket rotors are used, depending on whether rapid pelleting or precise layering is required. Ultracentrifuges are essential in workflows where even the slightest separation gradients make a difference—for example, purifying extracellular vesicles, characterizing macromolecular assemblies for cryo-electron microscopy (cryo-EM), or isolating genetic material from viral particles. At Wasteless Bio, we provide cost-effective access to surplus ultracentrifuges from top manufacturers. Every listing includes critical technical details such as maximum speed, RCF, rotor types, sample capacity, cooling capabilities, and safety features. By sourcing ultracentrifuges through Wasteless Bio, research labs can reduce equipment costs, extend instrument life cycles, and support sustainable, circular lab practices—without compromising on performance, compliance, or precision in high-resolution research.
