CHAPTER 1
Description
Introduction
This chapter provides a brief physical and functional description of the Beckman Coulter Allegra X-14
Series centrifuges. 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 Beckman Coulter Allegra X-14R (refrigerated) or Allegra X-14 (constant controlled
temperature) centrifuge (see Figure 1.1 ) is a benchtop centrifuge that generates centrifugal forces
required for a wide variety of applications. Together with the Beckman Coulter rotors designed for
use in this centrifuge, the centrifuge applications include:
• Routine processing such as sample preparations, pelleting, extractions, purifications,
concentrations, phase separations, receptor binding, and column centrifugations.
• Cell isolation.
• Binding studies and separation of whole blood.
• Processing large numbers of small-volume samples in multiwell plates for concentrating tissue-
culture cells, cloning and replicate studies, in-vitro cytotoxicity studies, receptor binding, and
genetic engineering experimentation.
• Rapid sedimentation of protein precipitates, large particles, and cell debris.
The Allegra X-14R and Allegra X-14 are microprocessor-controlled, providing interactive
operation. The instrument design features a brushless asynchronous motor, automatic rotor
identification system, program memory that enables repeated run conditions, temperature control
system, and a choice of acceleration and deceleration rates. User messages alert the operator to
conditions that may need attention.
