Tip Sealing And Electronic Tip Ejection; Safe-Cone Filters - Sartorius eLINE User Manual

4.4. Tip Sealing and Electronic Tip
Ejection
The pipette tips are recommended for use with
eLINE® pipettes. The eLINE® multichannel pipettes are
provided with a spring loaded OPTILOAD tip cones for
optimal tip sealing.
For easy and effortless tip ejection all eLINE®
electronic pipettes are equipped with the electronic
tip ejection feature. There are two tip ejection buttons
conveniently placed on the either side of the start
button to ensure easy reach for both right and left
handed users.
Tip ejection: When the pipetting cycle is completed,
either of the buttons can be depressed to eject the tip.
NOTE:
The tip ejection function is frozen during the
pipetting cycle and can only be activated after the
tip is emptied. If needed the pipetting cycle can be
interrupted by pressing the enter button. The display
will show E (E=empty) and the tip is then emptied by
pressing the start button.

Safe-Cone Filters

The tip cone design of the eLINE® pipettes (>10 µl)
allows the use of Safe-Cone Filters in the tip cones.
These removable filters prevent liquids and liquid
vapours from entering the pipette and thus protects
the pipette from cross contamination and damage.
The Safe-Cone Filters are available as Standard or
Plus versions. It is recommended to use the Standard
Filter for general applications and the Plus Filter for
more demanding applications. The filters need to be
changed regularly. The interval for filter changing is
application dependant but the recommendation is
to change the filter daily (after 50 – 250 pipetting
cycles) and always in case of over-aspiration. The
filter forceps should be used to avoid touching the
soiled filters by hand. (See Chapter 2.1. for ordering
information.)
