The Bel-Art Frigimat dry ice maker, Japanese model number 388780013 by Scienceware, is used to create small amounts of dry ice in a laboratory or other setting. Dry ice is used to keep a substance or object cold in food handling and shipping, science, and medical applications, and is used to create a fog-type of atmosphere in the entertainment industry. This dry ice maker uses the time-tested Joule-Thompson (also called Joule-Kelvin or Kelvin-Joule) effect for gas expansion in a vacuum to produce dry ice. With this throttling process, CO2 will cool upon expansion. In approximately one to two minutes, the dry ice maker produces one solid, 454-gram block of dry ice that measures 11.0 (l) x 8.5 (w) cm [4.65 (l) x 3.65 (w) inches]. The block can be removed from the unit approximately 30 seconds after formation. Each 50-lb. cylinder of liquid CO2 (LCO2) with dip tube makes eight blocks of dry ice. The dry ice maker has an epoxy-coated steel frame, and an aluminum ice chamber for strength and dependability. Brass valves add strength and security. It has four non-skid rubber feet to prevent sliding, or skidding.
This dry ice maker includes a 1.8-meter (6-foot) nickel-plated copper connecting tube with standard CGA 320 (0.830-inch to 14-inch) thread couplings for attachment to an LCO2 cylinder (not included). It is a Japanese model for direct connection to an LCO2 tank. Threads on the LCO2 tank (supplied by tank manufacturer) must match Japanese model. Dry ice must be handled using insulated cryogenic gloves (sold separately). The dry ice maker’s dimensions are 30 (l) x 17 (h) x 13 (w) cm [12 (l) x 6.5 (h) x 5 (w) inches], and it weighs 7.9 lbs. with valve attachment. Dry ice temperature is -109.3 degrees F (-78.5 degrees C).
Dry ice, the solid form of carbon dioxide (CO2), is commonly used as a cooling agent when temperatures lower than conventional ice are desired, and liquid melt-water is not desired. Dry ice is made by compressing and cooling the gas form of CO2 until it becomes liquefied. With expansion, the liquid changes into a solid state, and is then hydraulically compressed into dry ice blocks, pellets or slices. Rather than melting, dry ice sublimates, turning back into gas, as the temperature rises. Under specific conditions, dry ice can create a fog-like effect. It is much heavier than frozen H2O, and can be handled using insulated cryogenic gloves for thermal protection. Dry ice is used in laboratory, and field applications in the food handling and shipping, medical, science, education, industrial cleaning, fire-fighting, and entertainment industries.
Since 1946, Bel-Art has been manufacturing and distributing scientific equipment such as lab ware, dry ice makers, desiccators, glassware, testing equipment, and safety supplies for the scientific and medical industries. With worldwide distribution, and facilities located in New Jersey, Maryland and Missouri, most Bel-Art products are manufactured in the USA. Bel-Art is the recipient of numerous awards, including the Presidential “E” Award by the US Department of Commerce for excellence in export sales.
