3. Put on gloves.
4. Apply a small amount of silicon grease into the end of a filter-tip.
5. Apply a small amount of silicon grease onto the surface of the O-rings, by just using a
fingertip moistened with grease.
6. Place the filter-tip onto the pipettor head and rotate the filter-tip on the pipettor head to
distribute the silicon grease evenly.
7. Make sure that the O-rings are only moistened with grease and that there are no clumps of
grease visible.
8. Make sure that there is no grease present on parts other than the O-rings, especially on the
bar on top and the opening of the pipettors.
Note: The filter-tips should sit flush against the upper white plastic bar if the O-rings are
properly greased. There should not be a gap. Excess or insufficient grease can affect the
performance of the EZ2.
Note: The opening in the nub of the pipettor should be checked after greasing to ensure no
grease is present within the opening.
