RECOMMENDATIONS
By using the different operating modes and various special functions,
several different liquid handling procedures are made possible. Two of
the modes (P and dd) feature an automatic blow-out and others leave an
excess liquid in the tip. The user should follow the recommendations below
to ensure optimal performance.
7.1. Dispensing with Blow-out
The pipetting and diluting mode have an automatic blow-out function,
followed by an immediate return of the piston to the ”home” position. To
avoid accidental aspiration of the liquid back into the tip, it is recommended
that the dispensing is always done above the liquid surface.
By holding the START button down during dispensing the piston will stop
in the lowest position. This allows the tip to be placed against the bottom
or the wall of the container. Once the liquid is dispensed, the tip can be
removed from the container and the START button released.
