VIAFLO Pipettes – Operating instructions V05 Introduction
1 Introduction
These operating instructions contain all the information required for installation, operation
and maintenance of the VIAFLO Electronic Pipettes. This chapter informs about the
symbols used in these operating instructions, the intended use of the VIAFLO Electronic
Pipettes and the general safety instructions.
1.1 Symbols used
The operating instructions specifically advise of residual risks with the following symbols:
ARNING
W
This safety symbol warns against hazards that could result in injury. Italso
indicates hazards for machinery, materials and the environment.
It is essential that you follow the corresponding precautions.
CAUTION
This symbol cautions against potential material damage or the loss of data in
a microprocessor controller. Follow the instructions.
OTE
N
This symbol identifies important notes regardi ng the correct operation of the
device and labour-saving features.
1.2 Intended use
VIAFLO Electronic Pipettes are microprocessor controlled and stepper motor driven
pipettes. They are used for aspirating and dispensing liquids in the volume range of 0.5 5000 µl using GripTip pipette tips.
www.integra-biosciences.com 7
VIAFLO Pipettes – Operating instructions V05 Introduction
1.3 Safety notes
VIAFLO Electronic Pipettes comply to the recognized safety regulations and is safe to
operate. VIAFLO Electronic Pipettes can only be operated when in perfect condition and
while observing these operating instructions.
The device may be associated with residual risks if it is used or operated improperly by
untrained personnel. Any person operating the VIAFLO Electronic Pipettes must have
read and understood these operating instructions, and particularly, the safety notes, or
must have been instructed by supervisors so that safe operation of the device is
guaranteed.
Use only an INTEGRA battery.
Regardless of the listed safety notes, additional applicable regulations and guidelines of
trade associations, health authorities, trade supervisory offices, etc. must be observed.
Do not open or modify the VIAFLO Electronic Pipettes in any way. Repairs may only be
performed by INTEGRA Biosciences AG or by an authorised after-sales service member.
Parts may be replaced with original INTEGRA Biosciences parts only.
ARNING
W
Do not use the VIAFLO Electronic Pipettes near flammable material or in
explosive areas. Also, do not pipette highly flammable liquids such as
acetone or ether.
When handling dangerous substances, comply with the material safety data
sheet (MSDS) and with all safety guidelines such as the use of protective
clothing and safety goggles.
CAUTION
Do not immerse the VIAFLO Electronic Pipettes in liquid. The fluid can
damage internal parts. Avoid pipetting of liquids whose vapors could attack
the materials PA (polyamide), POM (polyoxymethylene), FPM (fluor -rubber),
NBR (nitrile-rubber), CR (chloroprene), silicone. Corrosive vapors could also
damage metallic parts inside the device.
OTE
N
Prolonged exposure of the VIAFLO Electronic Pipettes to UV-light can cause
discolouration and/or yellowing of the control unit. However, this will not
affect the performance of the device in any way.

3.1 Operating environment
The VIAFLO Electronic Pipettes have been designed for use in a laboratory. They shall be
operated in a dry and dust-free location with a temperature of 5–40 °C and a maximal
(non-condensing) relative humidity of 80 %.
3.2 Charging the battery
All VIAFLO hand-held pipettes share the same rechargeable, long-life, lithium-ion battery
that has a capacity of 1050 mAmp/hours. The battery should be charged for at least one
hour before pipetting. A full charge takes 2.5 hours and will provide approximately 3500
pipetting cycles.
A battery indicator is provided on the pipette display (2.3.3
• Blinking red icon: Low battery. A recharging message will appear.
• Blinking grey icon: Pipette is recharging.
• Blinking green icon: Pipette is recharging and battery is 90% charged.
• Solid green icon: Battery is fully charged and the pipette is still connected to the mains
adapter.
• Three static grey bars: Battery is fully charged.
AUTION
C
Use only the approved INTEGRA battery, power supply or charging stand.
Use of an incompatible power transformer can damage the pipette.
Battery charging can take place in two ways, using a pipette charging stand or the
Universal Voltage Power Supply (UPS), that allows for pipetting while charging the battery,
see (“8.1
3.2.1 Charging the battery on a stand
Use one of the different charging stands - single position with two- (#4210) or four prong
connector (#4211), or four position with two prong connector (#4215) - to charge the
battery.
Accessories” on page 64).
Place the pipette on the charging stand by fitting the
power receptacle (15, on the top back of the pipette)
over the prong connector on the top of the stand.
Plug the cable of the adequate power supply to the
socket at the base of the stand (see “8.1

The pipette will turn fully on when placed on the stand. When the dimming time is achieved
the startup screen is displayed on the pipette. When the turnoff time is reached, the pipette
turns off. For disconnecting simply lift the pipette up from the stand.
3.2.2 Charging the battery with UPS
With the optional Universal Voltage Power Supply (UPS, #4200), you can use the pipette
while charging through the line cord.
Insert the UPS connector into the receptacle on the top back of the
pipette (14
It will take approximately 30 seconds of charging to store enough
voltage to begin running the motor.
The pipette will turn fully on when the line cord is connected. The current screen remains
displayed. If the pipette is idle while charging, the display may dim (see “4.1 Turn on/off
the device” on page 20), but it will continue to show the battery life indicator. When the
display shut off time is reached, the instrument will shut off.

AUTION
C
Remove hands from the Tri-lobe tip interface (12) at switch on and during
homing. Also do not touch the touch wheel, because it is calibrated during
the start up process.
The pipette flashes the startup screen and performs a full motor homing routine, ensuring
the motor is in the run position. “Home” is the base point for the pipette. Homing is the
process whereby the pipette motor moves the piston(s) to a sensor position. This position
ensures that no liquid remains in the tips. For the VOYAGER, homing also includes the tip
spacing motor. After homing, the tips move to the last position they occupied.
After homing the menu last used is displayed. Press the Back button (2

CAUTION
To ensure optimal performance of your VIAFLO Electronic Pipettes always
use GripTips which have been designated for the use with the VIAFLO
Electronic Pipettes, see “8.2
The unique tri-lobe design of the VIAFLO Electronic Pipettes reduces attachment and
ejection forces, ensures a perfect fitting to prevent the tips from falling off and to provide
a perfect sealing. On a multichannel pipette all tips sit on the same height.
Tri-lobes minimize contact surface and temporarily deforms the tip
shaft
Shoulder provides a positive stop to prevent over tightening and all
tips seal at the same height
O-ring provides forgiving and robust seal surface for the pipet tip
