The flow was visualized with a Spot II video camera attached to a Leitz Laborlux S microscope with 10x and 20x objectives.
Sequence 1:
Side view: Jurkat cell stream (above channel bottom) flowing beneath wash stream. q_r ~0.2, Pe = 1000. Cell stream (CVF = 0.2%) flow rate is q_s ~0.25 ml/min. 20x objective.
Sequence 2:
Top view: Jurkat cell stream flowing beneath wash stream with q_r ~0.20. Cell stream (CVF = 0.2%) flow rate is q_s ~0.50 ml/min. Image captured at mid region of channel. Pe = 2000.
