SAFETY PRECAUTIONS AND APPLICATION LIMITS
Before using the instrument for the first time, read the safety precautions and application limits
carefully. Socorex will not assume any responsibility for problems related to erroneous use of
the instrument.
jRefer to and follow regulations about handling
of potentially hazardous reagents
jBefore use, check tip/nozzle tightness and
working condition of the instrument
jEmergency stop: press the “set/stop” key to
interrupt immediately any plunger movement
in stepper and dilution modes
jDo not use the Acura®electro in areas where
there is explosion or flame hazard
jDo not place the Acura®electro on charging
stand with a filled tip
jDo not let liquid penetrate the pipette casing
jChange volumetric module only with charged
power handle in place
jDo not use any volumetric module (lower
assembly) not specifically intended for your
instrument
jInstrument should not be used at tempera-
tures below 5°C and over 40°C
jThis product should be used only for its
intended purpose
jMind possible hand-fatigue during serial pipet-
ting and its potential medical consequences
(such as repetitive strain injuries, RSI)
Pipette handling
jDo not use aggressive solutions (such as
acetone) to clean volumetric modules. Use
water or alcohol (ethanol) instead
jThe volumetric module (lower assembly) only
is autoclavable at 121°C. The control unit (up-
per assembly) is not autoclavable
jNo liquid must penetrate inside the pipette
control unit (upper assembly)
jRefer to instructions for any operation (main-
tenance, change of volumetric modules)
carried out on the instrument
jServicing of control unit must be done by
authorised, trained personnel only
jUse only Socorex original parts and accesso-
ries (power handle, pipette tips, spare parts)
Maintenance and sterilisation
jPower handle (battery) must be completely
charged before first use
jPower handle can be charged either sepa-
rately, or when placed on the instrument
jIn any case, do not re-charge instrument
before “low bat” signal appears on pipette
display
jDo not use any fast charger other than the
original one supplied by manufacturer
jDo not damage electrical cord or plug of
charger with heavy or sharp items
jDo not expose pipette, power handle, charg-
ing stand or fast charger to heat or liquid
spillage
jRemove power handle from the instrument
if it is stored for a long period of time; this
prevents discharge of the batteries
jRecycle used or damaged power handle ac-
cording to applicable local laws
jThe power handle will have longer life span if
the above instructions are followed carefully

INSTRUMENT DESCRIPTION
The Acura®electro is a motorized, microprocessor controlled air displacement pipette. Energy
is provided by a long life NiMH battery pack located in the pipette handle. This power handle
can be replaced with a fully charged one within seconds, thus ensuring continuous work-flow
without loss of set parameters. Acura®925 models allows precise and reproducible pipetting
within 0.25 µL to 1000 µL. 935 macromodels cover volumes from 0.25 to 10 mL. Multichannel
Acura®955 with 8 and 12 channel range between 0.5 µL and 350 µL. All volumetric modules
(lower assemblies) are interchangeable on the same control unit (pipette body). The Justip™
ejection system provides height adjustment of the single and multichannel tip ejector.

USE OF THE INSTRUMENT
Accessories supplied with the Acura®electro may vary, depending on country. Check exact contents
on packaging label. All elements also available separately. Refer to chapter “Ordering information”
for more details.
Note: Keep original packaging for adequate instrument protection during future transport or shipment.
Supply contents
The power handle fits at the back of the pipette control unit. Insert and click in as shown. The ini-
tialisation starts automatically, followed by a self-calibration test. The display shows “RE-CAL”.
Note: Charge power handle completely before first use.
Inserting power handle (fig. 4A)
To remove the handle from control unit, press lock trigger located at the bottom of the handle and
lift gently.
Note: Pipetting data are kept in memory even during battery change. They will show again automatically upon
re-inserting power handle.
Replacing power handle (fig. 4B)
The power handle can be charged in three dif-
ferent ways:
1) Attached to the instrument and placed
on the electro pipette charging stand
2) Alone, placed on the charging stand of
the electro pipette
3) Alone, placed on the compact battery
charging stand (to be ordered sepa-
rately)
Note: In all cases, check for correct plugging position
of fast charger according to symbols “
●▲ ■
” on
charging stand (see fig. 7 and 8).
The red light goes on when charger operates
The green light indicates that charging is com-
pleted and put on stand by with minimal energy
consumption.
Maximal battery capacity is obtained after a few
full charging/discharging cycles.
At maximum capacity, power handles allow for
over 1800 forward pipetting movements (full
plunger stroke on a single channel micropipette)
without recharging.
Note: If unused for 10 minutes, the Acura®electro switches automatically to an energy saving stand-by position
(display switches off) to provide the longest wireless pipetting time. Simply press start button to re-activate
instrument.

PROGRAMMING
The ergonomic shape of the Acura®electro allows long pipetting series without hand fatigue.
Place finger rest on the phalanx of forefinger. The thumb reaches naturally start button (1) and
ejector button (7), both easily activated. Multichannel casing (13) revolves to allow the selection
of the best working position.
Holding the electronic pipette (fig. 1)
Note: After selection of left or right display reading, the last pipetting mode used, will show again.
