SYSTEM AND METHOD FOR DISPENSING LIQUIDS

摘要

A method for depositing a volume of fluid relative to a surface (12) to produce a droplet (10) relative to the surface (12) comprising the steps of forming a bolus of liquid (116) relative to a dispensing member (100), causi ng the bolus of liquid (116) to make contact with the surface (12) thereby forming a bridge of liquid (220) between the dispensing member (100) and the surface (12), and retracting only a portion of the bolus of liquid (116) to break the bridge of liquid (220) between the dispensing member (100) and the surface (12) thereby depositing a droplet (10) on the surface (12). A volume of a droplet (10) can be ajusted by forming a bridge of liquid (220) between a dispensing member (100) while leaving a remaining droplet (10) of a differen t volume thanthe initial droplet (10). One or more droplets (10) can be interacted with by forming a bridge of liquid (220) and a surface (12) that includes an initial drplet (10) and breaking the bridge of liquid (220) between a dispensing member (100) and a surface (12) that includes one or mo re of the droplet (10) or droplets (10) and drowing at least a portion of the bridge of liquid (220) into an inner volume of the dispending member (100).< /SDOAB>
