3 - LIMITATIONS OF USE

• The SWIFTPET + may not be used for measuring substances, the vapours of which
damage the following plastics: PP , SI, ABS, EPDM, POM.
• The pipetting aid may not be used in an environment where explosion risk is present.
• Flammable liquids shall not be measured - in particular substances with flash-point below
0 °C (ether, acetone).
• The pipetting aid shall not be used for drawing acids with a concentration above 1 mol.
• The pipetting aid shall not be used for drawing solutions with a temperature above 50 °C.
• The pipetting aid may work in temperature range from +10 °C to +35 °C.

4 - TO SWITCH ON THE SWIFTPET +

The SWIFTPET + pipetting aid is switched on by pressing the aspiration button (fig. 1A) or
the dispense button (fig. 1B). The display will show the selected aspiration mode, dispense
mode and the battery level indicator (fig.2.3). Examples of the display indications are shown
in (fig. 5.1). The battery is discharged and requires charging if the indicator displays one
"bar" (fig. 5.3). When the battery is fully charged, the indicator displays three „bars" (fig. 5.1).
The SWIFTPET + switches off automatically if not used for 5 minutes.
The SWIFTPET + may be charged only with the original charger.
The mains voltage shall conform with the specification on the charger.
Charging shall be done in accordance with section 8 of the instruction manual.

5 - ASPIRATING AND DISPENSING LIQUIDS

Attaching a pipette
Before attaching a pipette check whether the pipette is not damaged, has no dents
or sharp edges in the gripping part. Check whether the gripping part is dry.
The pipette shall be gripped as close to the upper end as possible and carefully inserted
into the pipette holder until resistance is noticed (fig. 3A). Do not apply excessive force
so as not to damage thin pipettes and to avoid injury risk. A pipette that has been correctly
attached and sealed in the holder should not tilt to the sides.
After attaching a pipette hold the device in such a way as to keep the pipettor in vertical
position. The shape of the device casing makes it possible to put aside the pipetting aid with
an attached pipette. After finished work it is recommended not to leave the device
with an attached pipette for a longer period, for example overnight or over a weekend.
Do not put aside the pipetting aid if there is liquid in the pipette.
Filling the pipette
Before aspirating is started, set the suction speed switch using the HIGH/LOW switch (fig. 1C):
• HIGH position - fast aspirating (fig. 2.1)
• LOW position - slow aspirating (fig. 2.2)

It is recommended to choose the LOW position for pipettes with a volume up to 5 ml,
and the HIGH position for pipettes with a volume greater than 5 ml. Holding the pipetting
aid in such a way that the pipette is in vertical position immerse the pipette end in the liquid
to be drawn up (fig. 3B), and press the aspiration button gently. The pipette filling speed
depends on how deep the aspirating button has been pressed. The deeper the button
is pressed the faster the liquid is aspirated into the pipette.
It is recommended to draw a slightly greater liquid volume than required (due to meniscus
above the required volume mark), adjusting the aspiration speed, particularly in the final filling
stage, so as not to overfill the pipette.
Setting the volume
After filling the pipette its end shall be dried with absorbent paper, that does not leave impu-
rities, in order to remove the solution rests from the outside surface of the pipette. Then set
the required liquid volume precisely. Pressing the dispense button gently (fig. 3C), dispense
the excessive liquid from the pipette until the meniscus of the liquid aligns exactly with
the required volume mark on the pipette.
Emptying the pipette
Holding the vessel in inclined position, place the pipette end in contact with the vessel wall
and press the dispense button gently (fig. 3C). The dispensing intensity may be adjusted
depending on how deep the dispense button has been pressed. The deeper the button
is pressed the faster the outflow of liquid from the pipette.
The SWIFTPET + has two dispense modes. The dispense mode is selected with
the GRAV/BLOW switch (fig. 1D).
• GRAV position - the dispense is effected in gravity mode, which means that the liquid
flows out of the pipette by its own weight. The outflow speed is adjusted depending
on how deep the dispense button has been pressed (fig. 2.4).
• BLOW position - the dispense is effected in gravity mode like in the GRAV mode, however,
when the dispense button is pressed to the end position, the pump is started and fast
emptying of the pipette with a blow is effected (fig. 2.5).
Attention:
During gravimetrical dispensing the pipette is not completely emptied due to the
characteristics of pipettes used with the pipetting

6 - TROUBLESHOOTING

If during your work the functioning of the pipetting aid is incorrect, check the cause
and remove the fault.
