How Does Carbolime Work?
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.Carbolime contains a small amount of ethyl violet, which acts as a color indicator
when nearing absorption exhaustion.
Fresh Carbolime has a white to off-white color. As
CO2 absorption reaches it's capacity, the Carbolime granules distinctively change to violet. This violet color intensifies to indicate exhaustion of the soda lime. When the violet color has penetrated through
half the depth of the Carbolime absorber, the absorbent capacity of the canister is exhausted and the material
should be discarded and replaced.
It is essential to empty canisters immediately after exhaustion. If exhausted Carbolime is left to stand, the 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 should never be re-used. The absorbent should be changed when uncertain of
the state of hydration, such as if fresh gas flow has been left on for an extensive or indeterminate
amount of time.
