Note this is not the preferred method and it is rare you will need to usethis method.This must be done very carefully. First, remove the syringe from the pipette.As always when handling the syringe, be careful not to bend the needle. The wire shouldalways be inserted through the glass first, both to ensure that the clog is fully removedfrom the syringe and to decrease the likelihood of bending the syringe. It may bedifficult to insert the end of the wire from the glass bore into the metal needle; good lightand a magnifying glass will help.Continue to insert the wire until it emerges from the tip of the needle. Carefully pull thewire back through the needle and glass bore.Figure 5-3. Wire in needle.5.5 Removing pipetteThe pipette is held by the arm and connected to the tower by a black cable.
