Carbolime™ carbon dioxide absorbent is a granular soda lime absorbent for the efficient removal of carbon dioxide from closed and semi-closed patient breathing circuits. Carbolime™ is a quality compound which contains no potassium hydroxide(KOH). It is formed by proportionately mixing calcium hydroxide(Ca(OH)2) with a small amount of sodium Hydroxide(NaOH).
Carbolime™ is supplied as hard, irregularly shaped granules, which have been processed to remove dust formation from friction. Significant process improvements have resulted in enhancements in moisture content (12-19%), hardness, and porosity generation. As a result, Carbolime™ delivers dependable, efficient CO2 absorption.
Color Indication and Regeneration
Medical grade Carbolime™ contains a small amount of ethyl violet, which acts as a color indicator when the absorbent is nearing exhaustion. Carbolime™ color is white to off-white. As CO2 is absorbed, it reacts with the ethyl violet, which causes the granules to change to a purple color. The purple color will intensify to indicate exhaustion. When the deep purple color has penetrated to half the depth of the absorber, the used material should be discarded.
If exhausted material is left standing its color will slowly change back to white. Carbolime™ in this newly regenerated state should never be re-used as it will quickly turn purple almost immediately. Therefore it is essential to empty canisters immediately after use.
