Molecular Products - Sofnolime 812/NI 797 CO2 Absorbent

If you need Sofnolime look for further. We now have you covered. We will ship the 797/812 CO2 absorbent in 44LB kegs. We only sell non color indicating absorbent as rebreather divers should not be relying on a color indicator as a reliable method for evaluating use.


The 797 Grade has a smaller particle size (1.0 to 2.5 mm) and has a triangular shaped cross-section, which combine to give a higher CO2 absorption capacity compared with CD Grade. The 797 Grade is the one most widely used in modern rebreathers. It is generically referred to as “8-12 mesh” or simply “812” by divers because the granule sizes are similar to the apertures found in size 8 wire mesh up to apertures found in size 12 wire mesh.
