A fluid delivery system for aspirating liquid from a bottle and conveying the liquid to an analytical instrument while allowing ambient air or gas to enter the bottle to replace the aspirated liquid. The bottle opening is sealed by a valve. A tube extends from the valve to the liquid within the bottle. A coupling component is removably connected to the analytical instrument anti to the valve for operatively connecting the instrument to the tube.

A coupler for an aspirating fluid delivery system for conveying liquid from a source of liquid to be aspirated to a manifold fitting on an analytical instrument, said coupler comprising: (a) a main body portion which has a central longitudinal axis, an elongated outer surface which is substantially parallel to said longitudinal axis, and an elongated liquid passageway which is substantially parallel to said longitudinal axis; (b) a first end portion at one end of said main body portion which has a first end opening to said liquid passageway for operatively connecting said liquid passageway to said source of liquid; and (c) a second end portion at the opposite end of said main body portion from said one end, said second end portion having a connector fitting which is complementary with said manifold fitting, said connector fitting have a second end opening to said liquid passageway for connecting said liquid passageway to said manifold fitting, said connector fitting having a first tab which extends transversely away from said longitudinal axis and a second tab which extends transversely away from said longitudinal axis, one of said tabs having a stop flange at a first widthwise side of said one tab which extends toward said first end portion, said one tab having a bevelled cam surface at a second widthwise side of said one tab, said bevelled cam surface facing away from said stop flange and said first end portion.
