Abstract

An embodiment provides a nozzle, including: a conical-shaped portion having a first end and a second end substantially opposite the first end, wherein the first end has a smaller diameter than the second end; the first end having an attachment to hold the nozzle in a flow of fluid from an inlet, wherein the nozzle is positioned with the first end facing an inflow of a fluid and the second end facing a chamber; and the conical-shaped portion configured to direct the inflow of the fluid along an inner surface of the chamber, wherein the inflow of the fluid travels around the outer diameter of the conical-shaped portion. Other aspects are described and claimed.

First claim

What is claimed is:

1 . A nozzle, comprising:
a conical-shaped portion having a first end and a second end opposite the first end, wherein the first end has a smaller diameter than the second end; the first end having an attachment to hold the nozzle in a flow of fluid from an inlet, wherein the nozzle is positioned with the first end facing an inflow of a fluid and the second end facing a chamber; and the conical-shaped portion configured to direct the inflow of the fluid along an inner surface of the chamber, wherein the inflow of the fluid travels around the outer diameter of the conical-shaped portion, wherein the outer diameter of the conical-shaped portion is shaped complementary to the inner surface of the chamber.

2 . The nozzle of claim 1 , wherein the attachment is selected from the group consisting of: a snap, tab, ring, screw, bolt, press fit, and thermal welding.

3 . The nozzle of claim 1 , wherein the outer diameter of the conical-shaped portion further comprises spacers opposite the inner surface of the chamber creating a gap between the nozzle and the surface of the chamber.

4 . The nozzle of claim 1 , wherein the nozzle is rotatable along a longitudinal axis.

5 . The nozzle of claim 1 , wherein the outer diameter of the conical-shaped portion further comprises a plurality of vanes configured to rotate the nozzle from the inflow of the fluid.

6 . The nozzle of claim 1 , wherein a surface of the second end further comprises a plurality of stir bars, wherein the plurality of stir bars are configured to stir the fluid in the chamber.

7 . The nozzle of claim 1 , wherein an electromagnetic force rotates the nozzle along the longitudinal axis.

8 . The nozzle of claim 1 , wherein the inflow of the fluid along an inner surface of the chamber reduces biofilm on the inner surface of the chamber.

9 . The nozzle of claim 1 , wherein the chamber is a measurement cell of a colorimeter.

10 . A colorimeter measurement chamber, comprising:
an inlet; a chamber; and a nozzle; wherein the nozzle comprises a conical-shaped portion having a first end and a second end opposite the first end, wherein the first end has a smaller diameter than the second end, the first end having an attachment to hold the nozzle in a flow of fluid from the inlet, wherein the nozzle is positioned with the first end facing an inflow of a fluid and the second end facing the chamber; and the conical-shaped portion configured to direct the inflow of the fluid along an inner surface of the chamber, wherein the inflow of the fluid travels around the outer diameter of the conical-shaped portion, wherein the outer diameter of the conical-shaped portion is shaped complementary to the inner surface of the chamber.

11 . The colorimeter measurement chamber of claim 10 , wherein the attachment is selected from the group consisting of: a snap, tab, ring, screw, bolt, press fit, and thermal welding.

12 . The colorimeter measurement chamber of claim 10 , wherein the outer diameter of the conical-shaped portion further comprises spacers opposite the inner surface of the chamber creating a gap between the nozzle and the surface of the chamber.

13 . The colorimeter measurement chamber of claim 10 , wherein the nozzle is rotatable along a longitudinal axis.

14 . The colorimeter measurement chamber of claim 10 , wherein the outer diameter of the conical-shaped portion further comprises a plurality of vanes configured to rotate the nozzle from the inflow of the fluid.

15 . The colorimeter measurement chamber of claim 10 , wherein a surface of the second end further comprises a plurality of stir bars, wherein the plurality of stir bars are configured to stir the fluid in the chamber.

16 . The colorimeter measurement chamber of claim 10 , where an electromagnetic force rotates the nozzle along the longitudinal axis.

17 . The colorimeter measurement chamber of claim 10 , wherein the inflow of the fluid along an inner surface of the chamber reduces biofilm on the inner surface of the chamber.

18 . The nozzle of claim 10 , wherein the inflow of the fluid along an inner surface of the chamber reduces biofilm on the inner surface of the chamber.

19 . A method for directing a flow of fluid in a colorimeter, comprising:
placing a nozzle in an inlet of a chamber of the colorimeter, wherein the nozzle comprises a conical-shaped portion having a first end and a second end substantially opposite the first end, wherein the first end has a smaller diameter than the second end, the first end having an attachment to hold the nozzle in a flow of fluid from an inlet, wherein the nozzle is positioned with the first end facing an inflow of a fluid and the second end facing a chamber; and the conical-shaped portion configured to direct the inflow of the fluid along an inner surface of the chamber, wherein the inflow of the fluid travels around the outer diameter of the conical-shaped portion.
