The Avanti J-26 XPI is a refrigerated centrifuge that generates centrifugal forces required for a wide variety of applications. Together with the Beckman Coulter rotors designed for use in this centrifuge, applications include:
• Routine processing such as sample preparations, pelleting, extractions, purifications, concentrations, phase separations, and spin column and spin filter centrifugations.
• Rapid sedimentation of protein precipitates, large particles, and cell debris.
• Preparation of subcellular organelles such as mitochondria, nuclei, chloroplasts, and crude microsomes.
• Separation of blood cells and cellular components.
• Pelleting of prokaryotic and eukaryotic cells.
• Gradient separation, for example, Ficoll-Hypaque and Percoll.
• Nucleic acid precipitation.
• Virus isolation.
• Bacteriophase isolation.
The Avanti J-26 XPI centrifuge is microprocessor-controlled, providing interactive operation. The instrument design features a brushless switched-reluctance drive motor, an automatic rotor identification system, FRS (friction reduction system), vacuum control circuitry, temperature control system, and programmable acceleration and deceleration times. Manual and programmed operation are available. User messages and/or audible signals are provided to alert you to conditions that may need attention.
The centrifuge can also be operated by the SpinTrace II system for centrifuge control and data collection. SpinTrace II software runs on a personal computer connected to up to thirty-two centrifuges. Contact your Beckman Coulter representative* for more information.
