14. The container of claim 9 further comprising:

a stopper disposed in said outlet of said second portion; and

tubing sealingly disposed within said stopper and in fluid communication with said first volume.

15. The container of claim 9 further comprising a plurality of lugs disposed on an outer surface of said second portion for alignment and operative engagement with a receptacle in a surgical console.

16. The container of claim 9 wherein said first side of said transverse wall defines a third volume between said transverse wall and said closed end of said first portion.

17. A container for delivery of a surgical fluid to a surgical handpiece, comprising:

a deformable liner having a first volume for receiving a surgical fluid for delivery to a surgical handpiece;

a body having a second volume receiving said deformable liner, an open mouth, a first transverse wall having an aperture disposed therethrough, a second transverse wall having first and second sides, said second side of said second transverse wall having an area for removably engaging a source of pressurized fluid so that said source of said pressurized fluid is in fluid communication with said aperture and a space between said body and said liner.

18. The container of claim 17 wherein said second side of said second transverse wall has a geometry for providing a binary signal indicative of a particular kind of said surgical fluid.

19. A container for delivery of a surgical fluid to a surgical handpiece, comprising:

a deformable liner having a first volume for receiving a surgical fluid for delivery to a surgical handpiece;

a body having a second volume receiving said deformable liner, an open mouth, a transverse wall having a first side, a second side, and an aperture disposed therethrough, said second side of said transverse wall having an area for removably engaging a source of pressurized fluid so that said source of said pressurized fluid is in fluid communication with said aperture and a space between said body and said liner.

20. The container of claim 19 wherein said second side of said transverse wall has a geometry for providing a binary signal indicative of a particular kind of said surgical fluid.

21. A system for delivering a surgical fluid to a liquefracture handpiece, comprising:
