Dry ice flakes are useful for packing around irregularly shaped items and are easily produced as needed with the Frigimat® Junior Dry Ice Maker. A brass nozzle screws onto any LCO2 cylinder equipped with a dip tube (cylinder & dip tube not supplied). When the cylinder valve is opened about 3/4 turn, LCO2 expands into the bag to create dry ice snow. The valve is then closed and the bag is ready to be removed and emptied. Makes .77kg (1.7 lb) of flakes per bag. The cone is 13cm (5") long x 6 cm (2-5/16") diameter at end. The bag is 15cm wide x 30cm long (6"x12").
