Abstract

A disposable container for fluid having an inlet and an outlet is provided. The container has a vortex breaker having a solid surface adapted to initially direct fluid away from the outlet and then through the outlet positioned adjacent the container outlet.

First claim

What is claimed:

1. A disposable container for a fluid comprising:
a disposable container having a volume, the container being formed of polymeric flexible walls,
an inlet through one of said walls,
an outlet through one of said walls, and
a vortex breaker, said vortex breaker being formed of a solid surface, a base and spaced apart solid supports between the solid surface and the base, the solid surface being secured to the base by the spaced apart solid supports, the base of the vortex breaker being secured to an inner surface of said container adjacent said outlet, wherein the base and the solid surface of the vortex breaker each have an outer diameter and the outer diameter of the base of the vortex breaker is greater than the outer diameter of the solid surface, the solid surface adapted to direct fluid initially away from said outlet and then through said outlet.

2. The container of claim 1 wherein the vortex breaker is formed as part of the outlet.

3. The container of claim 1 wherein the solid surface has a circular shape.

4. The container of claim 1 wherein the solid surface has a polygonal shape.

5. A fluid processing system which comprises:
a disposable container for a fluid comprising: a disposable container having a volume, the container being formed of polymeric flexible walls, an inlet through one of said walls, an outlet through one of said walls, and a vortex breaker, said vortex breaker being formed of a solid surface, a base and spaced apart solid supports between the solid surface and the base, the solid surface being secured to the base by the spaced apart solid supports, the base of the vortex breaker being secured to an inner surface of said container adjacent said outlet, wherein the base and the solid surface of the vortex breaker each have an outer diameter and the outer diameter of the base of the vortex breaker is greater than the outer diameter of the solid surface, the solid surface adapted to direct fluid initially away from said outlet and then through said outlet,
a unit operation downstream of the container, and
one or more conduits to affect flow from said container to said unit operation.

6. The system of claim 5 , wherein the unit operation is clarification, buffer preparation, media preparation, or virus removal.

7. A system for transferring a protein containing liquid comprising: a disposable container having a volume, the container being formed of:
polymeric flexible walls,
an inlet through one of said walls,
an outlet through one of said walls, the outlet being in fluid communication with a unit operation downstream of the container, and
a vortex breaker, said vortex breaker being formed of a solid surface, a base and spaced apart solid supports between the solid surface and the base, the solid surface being secured to the base by the spaced apart solid supports, the base of the vortex breaker being secured to an inner surface of said container adjacent said outlet, wherein the base and the solid surface of the vortex breaker each have an outer diameter and the outer diameter of the base of the vortex breaker is greater than the outer diameter of the solid surface, the solid surface adapted to direct fluid initially away from said outlet and then through said outlet to the unit operation.

8. The system of claim 7 wherein the unit operation is a normal flow filtration unit.

9. The system of claim 7 wherein the unit operation is a normal flow filtration unit selected from the group consisting of clarification depth filters, pre-filters and microporous membrane filters.

10. The system of claim 7 wherein the solid surface has a circular shape.

11. The system of claim 7 wherein the solid surface has a polygonal shape.

12. The system of claim 7 , wherein the unit operation is clarification, buffer preparation, media preparation, or virus removal.

13. A method of transferring a protein containing liquid from a container to a unit operation comprising:
a) providing a disposable container having a volume, the container being formed of polymeric flexible walls, the container having an inlet through one of said walls, an outlet through one of said walls, the outlet being in fluid communication with a unit operation downstream of the container and a vortex breaker, said vortex breaker being formed of a solid surface, a base and spaced apart solid supports between the solid surface and the base, the solid surface being secured to the base by the spaced apart solid supports, the base of the vortex breaker being secured to an inner surface of said container, adjacent said outlet, wherein the base and the solid surface of the vortex breaker each have an outer diameter and the outer diameter of the base of the vortex breaker is greater than the outer diameter of the solid surface, the solid surface adapted to direct fluid initially away from said outlet and then through said outlet and a pump between the outlet and the unit operation,
b) having a protein containing liquid in the container,
c) pumping the protein containing liquid through the vortex breaker and the outlet to the unit operation wherein the vortex breaker minimizes or inhibits the formation of one or more vortices at the outlet, and
d) recovering the liquid from the unit operation.

14. The method of claim 13 wherein the solid surface has a circular shape.

15. The method of claim 13 , wherein the unit operation is clarification, buffer preparation, media preparation, or virus removal.

16. The method of claim 13 wherein the solid surface has a polygonal shape.
