Produce the Dry Ice You Need Right in the Lab
The Frigimat® Dry Ice Maker eliminates the need to buy large quantities of dry ice when only a little is needed. It employs
the Joule-Thomson effect to produce a solid 454gm (16 oz) block of dry ice in one to two minutes. A brass relief valve safely
vents excess gas. Removing the dry ice block requires just 30 seconds. Each 50lb.cylinder of liquid CO2 will make 8 or 9 blocks of dry ice, each measuring 8.5cm (33⁄8") x 11cm (43⁄8") long. Made of epoxy-coated steel with an aluminum ice
chamber and brass valves with four non-skid rubber feet. Dimensions are 30 x 17 x 13cm (12 x 61⁄2 x 5") high. Shipping weight 5.5kg (12 lbs). Includes a 1.8m (6 feet) nickel plated copper connecting tube with standard GCA 320 (.830"-14) thread couplings for easy attachment to a LCO2 cylinder.
