Claims
- 1. A fluid transfer device comprising:
a cap-shaped device including a first port and a second port; a filtration vent extending from said first port, wherein said filtration vent filters air passing through said filtration vent; and a tubing segment assembly extending from said second port and forming a passageway for fluid transfers.
- 2. The device of claim 1 wherein said passageway is a closed fluid pathway.
- 3. The device of claim 1 wherein said cap-shaped device is configured for attachment to a rigid container.
- 4. The device of claim 3 wherein said container is a centrifugation container.
- 5. The device of claim 1 wherein said cap-shaped device is configured for attachment to a conical tube.
- 6. The device of claim 5 wherein said attachment is permanent.
- 7. The device of claim 5 wherein said attachment is removable.
- 8. The device of claim 5 wherein said conical tube is a centrifugation tube.
- 9. The device of claim 1 further comprising a second tubing segment extending from said second port within an interior portion of said cap-shaped device.
- 10. The device of claim 1 wherein said cap-shaped device is prefabricated onto a container and provided as an integral device.
- 11. A method of transferring fluids into or out of a container comprising:
removing a cap from a container while under a laminar flow hood; installing a cap-shaped device onto said container; transferring said container to a general laboratory environment; and connecting a closed system set to a tubing segment assembly of said cap-shaped device, whereby a fluid may be transferred into or out of said container in a closed system fluid pathway.
- 12. The method of claim 11 further comprising:
inverting said container, whereby fluid flows in a closed system fluid pathway from said container to said closed system set via gravity.
- 13. The method of claim 11 further comprising:
transferring a fluid from said closed system set into said container.
- 14. The method of claim 13 further comprising:
centrifuging said fluid within said container; and removing a portion of said fluid from said container.
- 15. The method of claim 14 further comprising:
connecting a closed system set to a tubing segment assembly of said cap-shaped device, whereby a fluid may be transferred into or out of said container in a closed system fluid pathway.
- 16. The method of claim 11 further comprising:
pumping a fluid from said container through a second tubing segment of said cap-shaped device, through said tubing segment assembly and into said closed system set.
- 17. A method of transferring fluids into or out of a container comprising:
adding a fluid to a container via a cap-shaped device of said container in a general laboratory environment, wherein a fluid pathway of said container and cap-shaped device is a closed system fluid pathway; centrifuging said fluid within said container; and removing a portion of said fluid from said container while maintaining said closed system fluid pathway.
- 18. The method of claim 17 further comprising:
connecting a closed system set to a tubing segment assembly of said cap-shaped device, whereby a fluid may be transferred into or out of said container in a closed system fluid pathway.
- 19. The method of claim 18 further comprising:
connecting a receiving container to said closed system set; positioning said receiving container a sufficient distance below said container; and aspirating said fluid from said container to said receiving container.
- 20. The method of claim 19 further comprising:
tipping said container to remove any residual fluid from said container.
