Filling the pipette
Before aspirating is started, set the speed by pressing the SPEED switch (fig. 1C) until the dis-
play shows the right speed (fig. 1E).
• HIGH speed - fast aspirating (fig. 2.1),
• LOW speed - slow aspirating (fig. 2.2).
It is recommended set the LOW speed when working with pipettes of volume up to 5 ml,
and the HIGH speed for pipettes of volume greater than 5 ml. Holding the pipette controller
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 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, so as not to overfill the
pipette.
Setting the volume
After the pipette is filled, dry the outside surface with absorbent paper that does not leave
impurities. 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 PRO has two dispense modes. The dispense mode is selected by succes-
sive pressing the MODE switch (fig. 1D) until the display shows the right mode (fig. 1E).
• gravity mode marked with the
gravity mode, which means that the liquid flows out of the pipette by its own weight.
• blow out mode marked with the
gravity mode, however, when the dispense button is pressed to the middle position, the
pump is started and fast emptying of the pipette with a blow out is effected.
CAUTION:
During gravimetrical dispensing the pipette is not completely emptied due to the characte -
ristics of pipettes used with the pipette controller.
