Claims
- 1. A container for holding both the clean and waste sheath fluid of a flow cytometer, said container comprising:
- a first collapsible reservoir having a first valve therein, said first reservoir containing a volume of clean sheath fluid;
- a second reservoir expandable to a second volume, said second reservoir having a second valve therein; and
- a single housing for both said first and second reservoirs, whereby as said volume of clean sheath fluid of said first reservoir decreases, said second volume of said second reservoir increases with the addition of waste sheath fluid.
- 2. The container of claim 1, wherein said first reservoir is made of a flexible waterproof material.
- 3. The container of claim 2, wherein said second reservoir is made of a flexible waterproof material.
- 4. The container of claim 3, wherein said first and second reservoirs are made from aluminum coated Mylar.TM..
- 5. The container of claim 1, wherein said second reservoir contains a volume of disinfectant sufficient to sterilize said waste sheath fluid.
- 6. The container of claim 1, wherein said housing is disposable.
- 7. The container of claim 6, wherein said housing is made of cardboard or plastic.
- 8. The container of claim 1, wherein said container has first and second cutouts and associated first and second tabs for holding said first and second valves.
- 9. The container of claim 1, wherein said second reservoir is placed above said first reservoir.
- 10. A method of reducing the combined volumes of two sheath fluid reservoirs, said method including the steps of:
- a. providing a first collapsible reservoir having a first valve therein, said first reservoir containing a volume of clean sheath fluid;
- b. providing a second reservoir expandable to a second volume, said second reservoir having a second valve therein;
- c. providing a single housing for both said first and second housings;
- d. removing clean sheath fluid from said first reservoir, via said first valve;
- e. cycling said removed clean sheath fluid through a flow cytometer; and
- f. filling said second reservoir, via said second valve, with said sheath fluid which has cycled through said flow cytometer.
- 11. The method of claim 10, wherein said second volume is essentially equal to said first volume.
- 12. The method of claim 10, wherein as the volume of said clean sheath fluid decreases, the volume of said sheath fluid which has been cycled through said flow cytometer increases, whereby the volume of fluid in first and second reservoirs remains essentially consistent.
