Abstract: The invention provides a device for dispensing accurately-controlled small quantities of at least one liquid, comprising a liquid supply (L); a gas supply (G), arranged to selectively supply a gas pressure; and a capillary duct (20) adapted to be filled with liquid to be dispensed, and to eject the liquid. The device has a filling configuration wherein liquid from the supply is in contact with an end (20a) of the capillary duct to fill the capillary duct with liquid; and a liquid separation and ejection configuration, in which liquid remaining in the liquid supply is separated from liquid that fills the capillary duct to form a discrete quantity (V) of liquid filling the capillary duct (20) out of contact with the remaining liquid of the liquid supply. The capillary duct, filled with this discrete quantity (V) of liquid then has one end in contact with the gas supply and another end in contact with the atmosphere. The discrete quantity of liquid (V), forming an exact dose of liquid to be dispensed, is ejectable from the second end (20b) of the capillary duct by the application of gas pressure.
Abstract translation: 本发明提供一种用于分配精确控制的少量至少一种液体的装置，包括液体供应源（L）; 设置成选择性地供应气体压力的气体供应源（G）; 和适于填充待分配液体的毛细管道（20），并喷射液体。 该装置具有填充构造，其中来自供应的液体与毛细管的端部（20a）接触，以用液体填充毛细管; 以及液体分离和喷射构造，其中残留在液体供应中的液体与填充毛细管的液体分离，以形成填充毛细管（20）的液体的离散量（V），与液体的剩余液体不接触 液体供应。 填充有这种离散量（V）的液体的毛细管具有一端与气体供应接触，另一端与大气接触。 形成待分配液体的精确剂量的液体（V）的离散量可通过施加气体压力从毛细管的第二端（20b）喷出。
