The flow cell allows fast and simple removal and replacement of substrates while insuring a tight seal around the substrate to minimize {TAIL ~ the leakage} of reagents in the flow cell, and it locates the active surface of the substrate at the focal plane of the image former with {HEAD ~ a high degree} of accuracy and repeatability
