BENEFITS
•
•
•
•
•
•
Rotor exchange
in
10 secondes
AUTO-LOCK
A choice of 9 angle and swing-out
rotors : 32 x 16 ml, 8 x 50 ml conical,
8 x 50 ml, 14 x 50 ml, 8 x 100 ml,
6 x 250 ml, 6 x 500 ml, 4 x 100 ml…
(up to 63,400 x g).
AUTO-LOCK : new rotor mounting system
locks the rotor onto the drive for
absolute security in centrifugation.
Record rotor exchange time - under 10
seconds.
VIDEOset graphic control system for
instant understanding of operation.
AUTO-LOCK makes the KR25i the first centrifuge
in its class on which the rotors can be changed
so easily, in absolute safety and in record time.
Exchanging a 6 x 500 ml rotor for an 8 x 50 ml
or a 4 x 100 ml (swing-out) is carried out in
under 10 seconds!
AUTO-LOCK : Instant rotor exchange
Lifetime guarantee of reproducibility from run-to-run with the High Reproducibility
Factor (integral).
Holds low temperature at high speed with its TFT system.
• CQCStm traceability system for samples, centrifuge and operators.
* KR25i with AKL50.22 (8 x 50 ml) rotor.

• The KR25i complies fully with the
most exacting international standards
concerning safety in centrifugation
: EN 1010-2-020 - imbalance
detection and shutdown, lid
interlock,armour plating,automatic
rotor detection, auto-diagnostics…
• The KR25i is the first centrifuge in
its category to be fitted with the
AUTO-LOCK system :
- For maximum security when
mounting rotors with or without
lid.
- For rapid fitting and removal of
rotors without the use of any
tools.
Excellent maintenance of sample temperature
and optimized heat exchange are assured
by the patented TFT (Thin Film
Technology) cooling systems with refrigerant
fluid totally integrated within the wall and
the bowl.
With its pre-cool function (4°C/2000 rpm/15
min) the KR25i is always ready to keep the
samples cool.
Centrifugal acceleration (x g)
Equivalent separations at different ‘g’
MAXIMUM SECURITY
ABSOLUTE CONTROL
Time
duration
Temperature compensation eliminates the
usual differences between sample of bowl
temperatures.
For a higher quality of separation :
•
•
•
Microprocessor control of all parameters.
Allowance for sample radius to achieve
true “g” force.
Choice of 100 run profiles to match the
sample needs (10 acceleration and 10
braking rates).
Separation reproducibility guaranteed :
•
High Reproducibility Factor ensures that
the same total force is applied to the
samples from run to run, whatever the
rotor, load, fluctuating mains voltage …)

SIMPLICITY AND EASE OF USE
EASY GRAPHIC USER INTERFACE
• The unique VIDEOset graphic control
system is pleasant and easy to use. The
user is guided intuitively and has no
need of a manual.
•
Set and actual run parameters can be
displayed simultaneously thus assuring
the user.
• A minimum of keys for a maximum of
functions.
.
Start the run.
Modify program parameter
values.
Create a set of parameter
values.
Store the set of parameter
values.
Access to advanced parameters
(radius programming,
high reproducibility factor/
integral, temperature compensation).

UNEQUALLED CONVENIENCE
• Inclined flat screen and keyboard
accessibly situated at the front of the
centrifuge.
• Automatic lid opening assisted by gas
springs and giving access to the front
and both sides of the centrifuge.
• Minimum lab space and ideal working
height (945 mm/37.2 in) for optimum
sample handling.
• Induction motor is maintenance-free
and exceptionally quiet (

TRACEBILITY AND CENTRIFUGATION
The IA-CQCS (Centrifugation Quality
Control System) is designed to optimize and
facilitate the traceability of the separation
process during the centrifugation phase.
• Connection of 1 to 32 centrifuges, type
KR4.22 or KR4i, all versions included.
• Simultaneous display and transfer to PC of
all information relating to the runs (sample,
centrifuge, operator and program identities,
speed or RCF, time temperature, etc.)
• Automatic storage of run data on hard or
floppy disk.
• Capture and exploitation of results by LIMS
(laboratory information management systems).
• Printout of reports, including graphics at
the end of the run.
Supplementary information on AI-CQCS in brochure Cat N° 89001263
TIME AND SPACE SAVING : ECONOMY
AUTO-LOCK : Absolutely no tool needed for
rotor locking and unlocking.
The most compact centrifuge in its category:
(H xW x D) 960 x 787 x 690 mm.
• Search facility for previous runs (by date,
sample number…)
• Ease of use - few keys and no
hidden menus.
• Remote diagnostic function.
• Traceability of runs with curves of speed
and temperature.
Sample, operator and centrifuge traceability
•
•
•
•
Sample traceability.
Centrifuge traceability.
Operator traceability.
Aid to maintenance.
A range of 8 high-speed rotors and more
than 40 accessories give the widest choice
of solutions for sample preparation.
