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 few blocks are needed. It employs the Joule-Thomson effect to produce a solid 454 gm (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 50 lb. cylinder of liquid CO2 will make 8 to 9 blocks of dry ice, each measuring 8.5cm (3 1⁄8") x 11cm (4 3⁄8"). The unit is made from epoxy-coated steel with an aluminum ice chamber and brass valves with four non-skid rubber feet. Dimensions are 30 x 17 x 13 cm H (12 x 6½ x 5"). Shipping weight: 5.5kg (12 lbs) and includes a 1.8m (6 ft) nickel-plated copper connecting tube with standard GCA 320 (0.830" – 14) thread couplings for easy attachment to an LCO2 cylinder.
