EquipmentOptima XPN-90 Ultracentrifuge

The Beckman Coulter Optima XPN-90 Ultracentrifuge is a high-performance, floor-standing instrument engineered for advanced separation of biological and chemical samples at ultrahigh speeds. Operating at up to 90,000 rpm with forces exceeding 600,000 × g, it provides precise, reproducible fractionation of macromolecules, viruses, organelles, nanoparticles, and other subcellular components. It forms part of the New Zealand Analytical Ultracentrifugation Centre (NZAUC) which is housed here at the University of Canterbury. Featuring an intuitive touchscreen interface and powerful data management capabilities through Beckman’s eXpert system, the Optima XPN-90 allows full control and real-time monitoring of run parameters, rotor life, and performance data, enhancing both efficiency and safety. It is compatible with a wide range of fixed-angle and swinging-bucket rotors, supporting diverse sample volumes and gradient media for analytical or preparative applications. The system’s advanced vacuum, imbalance detection, and thermoelectric temperature control ensure stable, energy-efficient operation with minimal sample disturbance. Applications include viral vector purification, liposome and exosome isolation, proteomic and genomic separations, and density gradient analyses in molecular biology, biochemistry, and nanotechnology research. Designed for both academic and industrial laboratories, the Optima XPN-90 combines cutting-edge technology, data connectivity, and robust performance to deliver consistent, high-resolution separations critical to modern analytical and preparative workflows.
