The carbon dioxide (CO2) absorbents we sell are for use in recreational SCUBA diving rebreathers. Because there are a great many types and formulations of carbon dioxide absorbent, it is critical to use only the specific CO2 absorbent recommended by the manufacturer of your specific model rebreather. Proper storage is a necessity as well, in order to maintain the correct balance and distribution of moisture
Advice regarding travel with Sofnolime™
Some individuals are reporting difficulty transporting Sofnolime, particularly by commercial airline. Occasionally the transport personnel will arbitrarily decide Sofnolime is a hazardous material (HazMat) and either refuse it or levy special HazMat surcharges. Although all carriers have this right, in these cases it might help to have a copy of the Material Safety Data Sheet (MSDS) at hand. Point out section #14 of the MSDS that indicates Sofnolime has no transport restrictions or UN Number. As a last resort, you might produce a copy of the letter from Molecular Products declaring Sofnolime is classified as non-hazardous for transport. As a practical matter, our customers tell us it is nearly impossible to get airlines to accept containers that have been opened, regardless of documentation.
