EZ-EM Large Volume Enema set is marked as a 2.5 Liter, or 2.6 quarts but will actually fill to 3 Liters or a little over 3 quarts and is a general purpose enema administration kit that includes the flexible vinyl transparent bag with attached 5/16" vinyl tubing that goes perfectly with our silicone nozzles. It also includes a standard small barium enema tip, tubing flow clamp and a Screw-Cap closure. These are great bags and with proper care and cleaning can last for several years. These kits are getting hard to find but I'll keep them on the site as long as I can keep sourcing them or something of equal quality.
