(Repetitive strain injury) associated with routine work. It combines superior accuracy, precision
and robustness with advanced ergonomics design: it fits comfortably in either left or right hand
and allows a 360° rotating manifold. This pipette is a unique electronic pipette as easy to use as a
mechanical one. With only two buttons to enable the pipette and reach modes/functions: The
Push-Button to set the volume by turning the button left or right and pipette with a simple push and
the Mode-Button to access the 5 essential pipetting modes and pipettes functions. The VWR
electronic pipette has an intuitive interface with 5 available modes: PIPET, REPETITIVE, MIX,
REVERSE and CUSTOM Mode into which you can create, quickly and easily, specific protocols
thanks to VWR Protocol Builder Software .

3GETTING STARTED
Switch on your VWR Electronic Pipette:
Press the Push-button to activate the pipette. The start-up screen
appears:
The pipette will do a self-calibration test, the firmware resets
the piston.
During initialization, displayed on the screen, you will see the
volume range,version of firmware and the number of readjustments.
Your VWR Electronic Pipette is preset on PIPET mode and is now
ready to pipette (see Chapter 5).
VWR Electronic Pipette goes into sleep mode after 3 minutes
of inactivity. The display will shut off.
Just press the Push-button to reactivate the pipette, your last setting
and pipetting mode will appear on the screen.

VWR Electronic Pipette single and multichannel models:
Upper part:
VWR Electronic Pipette is provided with a minimal battery charge. Before
using it, we strongly recommend you to fully charge the battery. VWR
Electronic pipette charges 80 % of its full battery capacity in less than an hour;
it takes three hours to fully charge the battery.
Please refer to VWR Electronic pipette power management for charging
procedure.

Reset: To reset your pipette, simultaneously press on the Push-button and the Mode-button for at
least 5 seconds.
Switch off: To switch off your VWR Electronic Pipette, press the Push-button for at least 5 sec.
Display: The VWR Electronic Pipette display is an OLED screen. It shows the current mode and
operation step, pipetting volume, battery indicator and piston status (aspirated and dispensed
volume) in real time.
Warning messages appear in the place of volume.
5 PIPETTING
Your VWR Electronic Pipette is set by default on “PIPET Mode”, that means forward pipetting.
You can select a volume and start to pipette.
Switch on
Press Push-button.
Adjust the volume setting
• Hold your VWR electronic pipette in pipette position.
• Turn the Push-button half way (quite quickly), the screen will display:
“click to change volume”
• Now press the Push-button; the volume on the display will start blinking, you can now adjust the
volume:
• Turn the Push-button either clockwise to decrease volume or counter clockwise to increase
volume, like indicated on the button.
• Press the Push-button one time when finished. The volume is locked.
You are ready to pipette!
6 PIPETTING MODES
VWR Electronic Pipette offers essential pipette modes for a large number of applications: you will
find all pipetting modes in the menu (for system settings refer to the chapters 7 and 13). Access the
menu by pushing the Mode-button. To choose one of the pipetting modes, turn the
Push-button and confirm your selection with a simple click!
The tip can be emptied at any time during a pipetting cycle. To do so, turn
the Push-button quickly: the message “click to abort” will appear on the
screen. Click on the Push-button to validate: the liquid will be dispensed
and an automatic purge followed by piston reset to zero will occur.

9
PIPET Mode
This is the classic pipette mode (forward pipetting), your pipette is simply aspirating and dispensing.
• Fit a suitable tip
• Press the Push-button to aspirate the selected volume.
• To dispense: Click (press and release) the Push-button. Three things happen: sample dispense,
automatic purge and piston reset to zero.
Or Keep your thumb pressing the Push-button until the end of the dispense cycle: the piston reset
takes place after releasing the Push-button again. This feature enables you to remove the tip from
the liquid, without aspirating anything.
• Eject tip by pressing the ejection button.
VWR electronic pipette is ready again for next pipetting cycle while maintaining the volume and the
last settings!
Continue pipetting as you would as if you were using a mechanical pipette.
REPETITIVE Mode
The REPETITIVE Mode allows you to distribute the same volume repeatedly in predefined number
(N) of equal aliquots. You supply the aliquot volume (AV) and the pipette automatically calculates
the number of aliquots possible from the nominal (maximum) volume (NV) of the pipette as follows:
N = NV/AV (e.g. 120 μL x 10 for VWR 1200).
You also can decrease the number of repetitions (e.g. 120 μL x 10-(n ≥1) for VWR 1200).
• Press the Mode-button to access system menu, where you can choose between different pipette
modes by turning left or right the Push-button.
Select REPETITIVE Mode by turning the Push-button.To confirm your selection click on the
Push-button.
• Turn the Push-button half way, the screen will display: “click to change volume”

10
• Set the aliquot volume : Press the Push-button; the volume on the display will start to blink, you
can now adjust the volume by turning left or right the Push-button. Then, click on the Push-button to
confirm the volume choosen. The maximum number of aliquots has been calculated by your
pipette.
• Set the aliquot number: the Aliquot numbers will start blinking: set the desired numbers of aliquots
by turning the Push-button and click again to confirm your settings.
You are ready to pipette!
1/ Fit a suitable tip
2/ Click the Push-button to aspirate total volume. The volume aspirated will be a little bit more than
required (extra volume). The extra volume is necessary to ensure equal operating conditions for
each dispensed aliquot.
3/ To dispense: click the Push-button. “DISCARD”appears on the screen. Discard the extra volume
and continue dispensing the aliquots. VWR electronic pipette distributes the aliquot volume each
time you click the push-button. The number of aliquots left to dispense is displayed on the screen.
A warning beep indicates the last aliquot!
4./ To purge: Press the Push-button, “PURGE”appears on the screen, click again to purge and
reset the piston. Keep your thumb pressing the push-button until the end of the purge: the piston
reset takes place after you release the push-button again. This feature enables you to remove the
tip from the liquid, without aspirating anything.
5/ Eject tip by pressing the ejection button.
