CHAPTER 1
Description
Introduction
This chapter provides a brief physical and functional description of the Beckman Coulter Avanti J-E
centrifuge. The operating controls and indicators are also described; instructions for their use are in
CHAPTER 2, Operation. Chemical compatibilities of materials listed in this manual can be found in
Chemical Resistances (publication IN-175). Refer to the applicable rotor manuals for rotor descriptions.
Centrifuge Function and Safety Features
Centrifuge Function
The Avanti J-E high-performance centrifuge (see Figure 1.1) is a refrigerated centrifuge that
generates centrifugal forces required for a wide variety of applications. Together with the
compatible Beckman Coulter rotors, 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.
• Gradient separation, for example, Ficoll-Hypaque and Percoll.
The Avanti J-E is microprocessor-controlled, providing interactive operation. The instrument
design features a brushless switched-reluctance drive motor,
*
a temperature control system with
automatic temperature compensation unique for each compatible rotor, and selectable
acceleration and deceleration rates.
