Description
• Bacteriophage isolation.
• Gradient separation, for example, Ficoll-Hypaque
1
and Percoll.
1
The Avanti J-25I centrifuge is microprocessor-controlled, providing
interactive operation.
2
The instrument design features a brushless
switched-reluctance drive motor,
3
automatic rotor identification
system, FRS (friction reduction system) vacuum control circuitry,
temperature control system, and programmable acceleration and
deceleration times.
The user interface consists of a separate Actual Value Display Setup
Screen, a numerical keypad, and other system control and parameter
entry touch keys. User messages and/or audible signals alert the
operator to conditions that may need attention.
Manual and programmed operation are available.
• In manual operation, you enter the individual run parameters
before beginning each run.
• In programmed operation, you enter and save sets of run parame-
ters. To perform a run, you recall and start a previously saved
program, enabling quick and accurate run duplication. Up to thirty
programs can be saved, each containing one or two steps.
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.
SAFETY FEATURES
Safety features include the following.
• An electromechanical door lock system prevents operator contact
with spinning rotors and prevents run initiation unless the door is
closed and locked. The door locks when [
ENTER
] an [
START
] are
pressed, or when the POWER switch is turned off. The exception
to this is ZONAL mode, in which open-door operation up to
3000 rpm is allowed.
