Carbolime® CO2 Absorbent Sodasorb (12 pk Cylindrical Canisters)
Carbolime® CO2 Absorbent Cylindrical Canister 1 kg Calcium Hydroxide / Sodium Hydroxide (12pk Canisters)
Carbolime, a carbon dioxide absorbent, is a granular soda lime-based compound intended for the efficient removal of carbon dioxide from closed and semi-closed patient breathing circuits without the use of potassium hydroxide (KOH).
Carbolime contains a precise mixture of calcium hydroxide (Ca(OH)2), water, and a small amount of sodium hydroxide (NaOH), with ethyl violet indicator dye to provide white-to-violet color change upon exhaustion.
Available in several convenient package sizes, Carbolime is supplied as hard, irregularly shaped granules that have been processed to minimize dust formation from friction. Carbolime has a moisture content of 12-19% and is manufactured with a hardness and porosity which delivers dependable, efficient CO2 absorption.
Allied’s Carbolime meets or exceeds the United States Pharmacopoeia National Formulary specifications for soda lime and is manufactured in accordance with the United States Food and Drug Administration (FDA), Quality System Requirements (QSR), and ISO 13485 guidelines.
STANDARD FEATURES
- No KOH - Minimum anesthetic agent degradation (e.g., sevoflurane to Compound A and other toxic products) compared to other brands containing potassium hydroxide.
- Low Dust - Minimum dust levels with the benefits of high surface area and graded particle size.
- Low risk of carbon monoxide formation due to good resistance of dry gas desiccation.
- Low Bulk Density - Less weight required to fill absorber and, therefore, less waste when refilling frequently (e.g., daily) prior to full exhaustion.
- Low odor due to reliable control of indicator dye concentration. Dye overdosing causes amines to be released; dye underdosing causes poor/no color change.
COLOR INDICATOR AND REGENERATION
Medical-grade Carbolime contains a small amount of ethyl violet, which acts as a color indicator when the absorbent is nearing exhaustion. Fresh Carbolime has a white to off-white color. As CO2 absorption reaches capacity, the granules distinctively change to violet. The violet color will intensify to indicate exhaustion of the soda lime. When the violet color has penetrated through half the depth of the absorber, the absorbent capacity of the canister is exhausted, and the material should be discarded.
It is essential to empty canisters immediately after exhaustion. Like all soda lime-based CO2 absorbents, if exhausted Carbolime is left to stand, its violet color will begin to revert to white within a few hours. Although Carbolime may appear to return to a fresh state, it cannot be regenerated, and it should never be re-used. The absorbent should be changed when uncertain of the state of hydration, such as if the fresh gas flow has been left on for an extensive or indeterminate amount of time.
