Droplets observed on worktable
The pipettor is dripping liquid. Check that the reagent
bottles contain the correct buffers and are correctly
placed in the reagent bottle rack. Be sure to use the right

refilled, make sure that the correct tips were used.

could be detected, change O-Ring as described in
