Operate these dry ice makers by screwing the nozzle directly to a cylinder of compressed LCO₂ with a CGA connector. Note: cylinder must have a dip tube. Bag is secured to cone on the nozzle with the clamp. Compressed LCO₂ expands into the bag and creates dry-ice snow. The ice may be squeezed into a hard pack or left in flake form depending on intended use. It makes 0.77 kg (1.7 lb) of flakes per bag. The cone is 13 cm (5") long x 6 cm (2-5⁄16") diameter at end. The bag is 15 cm (6") W x 30 cm (12") L.
