An apparatus including a fluid reservoir and a compressible metering chamber including a first end coupled to the fluid reservoir and a second end. The apparatus further including a valve coupled to the second end of the metering chamber and a nozzle coupled to the valve. A system including linearly translatable cartridge mounting assembly having a plurality of fluid dispensing cartridge mounting stations and a plurality of fluid dispensing cartridges mounted to respective fluid dispensing cartridge mounting stations. The system further including a plurality of compression assemblies coupled to respective fluid dispensing cartridges and a receiving assembly positioned beneath the mounting assembly. A method includes positioning a fluid dispensing cartridge comprising a fluid reservoir and a metering chamber over a sample retaining member, applying a compressive force to the metering chamber to eject a predetermined amount of fluid and removing the compressive force to refill the metering chamber.
1. An apparatus comprising: a fluid reservoir;a compressible metering chamber comprising a first end coupled to the fluid reservoir and a second end;a valve coupled to the second end of the metering chamber, the valve having a deformable base member and a deformable skirt member positioned around th
1. An apparatus comprising: a fluid reservoir;a compressible metering chamber comprising a first end coupled to the fluid reservoir and a second end;a valve coupled to the second end of the metering chamber, the valve having a deformable base member and a deformable skirt member positioned around the deformable base member; anda nozzle coupled to the valve, the nozzle having a reservoir within which the valve is positioned, wherein the reservoir defines an annular chamber having an inner side and an outer side which are substantially parallel and face one another, wherein a distance between the inner side and the outer side define a gap, wherein a portion of the deformable skirt member lies in the gap, wherein a thickness of the gap is greater than a thickness of the portion of the deformable skirt member such that the deformable skirt member forms a seal with the outer side of the annular chamber when the deformable base member is in the open position and a seal with the inner side of the annular chamber when the deformable base member is in a closed position. 2. The apparatus of claim 1 wherein the fluid reservoir comprises a housing defining a chamber and an expandable bladder positioned within the chamber. 3. The apparatus of claim 2 wherein the expandable bladder comprises a quadrilateral cross section in the expanded configuration. 4. The apparatus of claim 2 wherein the expandable bladder comprises at least one pleat. 5. The apparatus of claim 1 wherein the first end is an unopposed fluid conduit formed by a connector inserted within the first end of the metering chamber and a fluid passes through the fluid conduit directly to the metering chamber. 6. The apparatus of claim 1 wherein the valve is the only valve coupled to the metering chamber. 7. The apparatus of claim 1 wherein the valve is a liquid retention valve. 8. The apparatus of claim 1 wherein the valve comprises flaps that open in response to compression of the metering chamber. 9. The apparatus of claim 1 wherein the valve comprises an opening having a single slit, Y or cross shaped dimension. 10. The apparatus of claim 1 wherein the metering chamber is a first metering chamber and a second metering chamber is coupled to the fluid reservoir. 11. The apparatus of claim 10 wherein the valve is a first valve coupled to the first metering chamber and a second valve is coupled to the second metering chamber. 12. The apparatus of claim 10 wherein the nozzle is a first nozzle coupled to the first metering chamber and a second nozzle is coupled to the second metering chamber. 13. The apparatus of claim 12 wherein the first nozzle comprises a first channel and the second nozzle comprises a second channel, the first channel directs a fluid flowing from the first nozzle toward a fluid flowing from the second nozzle. 14. The apparatus of claim 1 wherein the nozzle comprises a fluid conduit having a counter bore formed within an end of the fluid conduit. 15. The apparatus of claim 14 wherein the fluid conduit comprises a length greater than its width and the counter bore comprises a length less than the length of the fluid conduit and width greater than a width of the fluid conduit. 16. The apparatus of claim 1 wherein the compressible metering chamber is tapered. 17. The apparatus of claim 1 further comprising: a nozzle locking mechanism removably positioned around the metering chamber, wherein the nozzle locking mechanism secures the nozzle to the second end of the metering chamber. 18. An apparatus comprising: a fluid reservoir;a compressible metering chamber comprising a first end coupled to the fluid reservoir and a second end;a deformable valve coupled to the second end of the metering chamber; anda nozzle coupled to the deformable valve, wherein the nozzle defines a reservoir connected to a fluid outlet channel, wherein the reservoir comprises an annular chamber having an inner side and an outer side which are substantially parallel and face one another, wherein a distance between the inner side and the outer side define a gap, wherein a portion of the deformable valve lies in the gap, wherein a thickness of the gap is greater than a thickness of the portion of the deformable valve such that the portion of the deformable valve within the gap forms a seal with the outer side of the annular chamber when the deformable valve is in an open position and a seal with the inner side of the annular chamber when the deformable valve is in a closed position.
