Sodasorb® HP (High Performance) CO2 absorbent plays an essential role in commercial and recreational diving and underwater habitat applications by safely and efficiently removing exhaled CO2 from saturation breathing systems, closed-circuit rebreather gear, and hyperbaric chambers. Sodasorb HP is specially formulated to meet the performance demands of saturation diving, rebreather diving, and submarine activities, enabling military, commercial, scientific, and recreational divers to breathe safely on longer, deeper dives.
For years, submersibles and military, commercial and recreational divers using closed-circuit rebreathers have relied on market-leading Sodasorb HP absorbent in the 4-8 mesh grade formulation to remove expired CO2.
Sodasorb HP 4-8 is efficient - It's long-lasting formulation removes CO2 for hours.
- Sodasorb HP 4-8 is designed specifically for undersea applications - The 4-8 mesh grade is specially formulated with the right ingredients, moisture content, surface area, and density to support a multitude of undersea applications.
- Sodasorb HP is safe and simple to use - Its high-contrast color change lets you know when it's time to change.
- Sodasorb HP is also available without indicator, if desired.
* For best results, please refer to your breathing system manufacturer for direction on which mesh grade of Sodasorb HP is required for your unit and application.

Why is there indicating and non-indicating Sodasorb?
Many years ago the U.S. Military used indicating Sodasorb but they found that the ingredient used to change the color of the Sodasord from white to purple gave off a fishy odor. The U.S. Military decided to switch from indicating to non-indicating Sodadorb to resolve this issue. The manufacturer has since fixed the order issue by switching the indicating ingredient.
How would a customer know they need to change the SodaSorb if it’s not indicating?
If the customer is using non-indicating Sodasorb then they need to monitor the CO2 level in the chamber with an Analox 5001 Carbon Dioxide Analyzer. If the percentage starts to increase then the sodasorb most likely needs to be changed.
What is the difference between indicating and non-indicating SodaSorb?
Indicating SodaSorb turns purple as the carbon dioxide absorption capacity is depleted.
What is the difference between Sodasorb and Sofnolime?
The chemical composition differs slightly but the application and use is the same. Sodasorb is manufactured by Grace whereas Sofnolime is manufactured by another manufacturer.
How long should my Sodasorb last?
In a properly packed and well designed canister, approximately 100 grams of Sodasorb will absorb 15 liters of carbon dioxide before the exit gas exceeds 1% carbon dioxide (CO2). This assumes no significant amount of channeling through the absorbent. Hence, for an eight hour capacity, a canister should hold approximately 1 kilogram of Sodasorb absorbent.
High gas flows may impair the efficiency of CO2 absorption, if caking or decreased wetting of the Sodasorb absorbent occur. When residence time (time of contact between CO2 and absorbent) is less than 1 second, CO2 absorption capacity is greatly reduced.
