2- Press the push-button until it can
go no farther, to dispense the first
aliquot. This action also locks the
adjustment ring, if it was left un-
locked after setting the volume.
3- Release the push-button.
4- Repeat steps 1 to 3 for all but the
last aliquot, which normally would
not contain a complete aliquot. The
red plastic flag (E, page 10), when
completely visible, warns that it is
time to purge and eject the syringe
(or refill it).
5- You may purge the syringe at
any time by placing the tip into a
suitable recipient vessel and then
pushing filling-knob downwards to
its lowest possible position.
Operator error is minimized by applying
axial pressure on the dampened push-
button, ensuring that each aliquot is com-
pletely dispensed, and that the repeatabil-
ity is maximized (see ‘Recommendations’).
Ejecting the Distritip
You must change the syringe before aspirating
from a different sample or from a different liquid.
DistriTips may discarded without having to touch
them, thus avoiding any risk to the operator. To
remove a DistriTip, perform the following steps.
1- If required, purge the DistriTip by placing the
tip into a suitable recipient vessel, and then
pushing filling-knob downwards to its lowest
possible position.
2- Hold the filling-knob at its lowest possible
position with one hand and rotate the DistriTip
through about 90° with the other (as if snapping-
off the syringe).
3- When fitting a new DistriTip, remember to
check that its capacity matches the volume
range setting of your Distriman.
