Filling the PD-Tip
1.
Push the locking/filling lever to the
lower stop.
2.
Immerse the orifice of the PD-Tip
vertically into the liquid to a depth of
3 - 10 mm.

to the upper stop to avoid the forma-
tion of air bubbles.
Aspirating Liquid
Note:
Any small air bubble near the piston can
be ignored since a locking mechanism
prevents the residual volume from being
dispensed inadvertently after the final
complete dispensing step.
