Sofnolime Carbon Dioxide Absorbent for the removal of carbon Dioxide from breathable gas in diving rebreathers.
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.

• The Sofnolime sold by American Diving Supply is non-color indicating, meaning that it lacks dyes that temporarily change color as the CO₂ is being absorbed. Rebreather divers should not rely on a color indicator as a reliable method for evaluating continued usage.
