In one embodiment, photonic switching fabric includes an input photonic commutator switch configured to receive a photonic frame stream including a plurality of containerized photonic packets and a first high port count photonic switch coupled to the input photonic commutator switch. The apparatus has a pad retainer for a removable spreader pad and a reservoir chamber for flowable material pivotally attached to the pad retainer to permit pivoting of the reservoir chamber frontwards and backwards. The pipette tips may be automatically engaged and locked into place by the pipettor and may be automatically disengaged to enable highly-automated pipetting processes for industrial and laboratory purposes. The method may include determining drifting in the movement of the data eye, and correcting the drifting based on adjusting one or more existing phase interpolator values associated with the movements of the data eye.
