Abstract
The current document is directed to a fluid dispensing nozzle assembly for use with a multi-well synthesizer and in other reagent distribution systems. In certain implementations, a fluid dispensing nozzle assembly comprises a nozzle body with a built-in dispenser tube, a reagent inlet tube, and a fitting that securely connects the inlet tube to the nozzle body. The nozzle body with the built-in dispenser tube and the reagent inlet tube are securely attached to one another by various coupling elements or adhesive material to ensure that liquid is transmitted through the inlet tube without leaking into the nozzle body and other undesired areas.
Claims19
A fluid dispensing nozzle assembly that dispenses a reagent fluid input to the fluid dispensing nozzle assembly, the fluid dispensing nozzle assembly comprising:
- a nozzle body;
- a built-in dispenser tube that dispenses the reagent fluid, the built-in dispenser tube is mounted within and affixed to the nozzle body, the built-in dispenser tube includes a first end and a second end, the second end of the built-in dispenser tube defines a dispense tip that dispenses the reagent fluid;
- a reagent inlet tube, mounted to and within the nozzle body, a first end of the reagent inlet tube external to the nozzle body and a second end of the reagent inlet tube fluidly coupled to the first end of the built-in dispenser tube through an adapter bushing having an inner bore slightly larger than an inner bore of the built-in dispenser tube and an inner bore of the reagent inlet tube;
- and
- a wash-solvent channel that allows a wash solvent to flow over the dispense tip defined by the built-in dispenser tube that dispenses the reagent fluid.
