Soda Lime 38 Lb. Tub, Color Changing CO2 Absorber

Soda lime is a high-grade granular product that effectively absorbs carbon dioxide that is produced as an anesthesia by-product.It is a mixture of calcium hydroxide Ca(OH)2 also known as lime plus a smaller amount of sodium hydroxide NaOH. Upon exposure to carbon dioxide CO2, the calcium hydroxide converts to calcium carbonate Ca(CO3). This prevents CO2 buildup in a re-breathing circuit.The sodium hydroxide acts as a catalyst in the process. No potassium hydroxide (KOH) is present in soda lime; this helps to avoid the formation of toxic compounds such as Compound A and carbon monoxide.Soda lime has a pH color change indicator that changes from white to violet when the soda lime needs to be changed. It will eventually return to its original color if not changed. Therefore, a good rule of thumb is to replace the soda lime every time the vaporizer is filled.Minimal dustNo KOH-minimizing chance of anesthetic reactions that produce toxinsIrregular particle size-creates more surface areaSaturation indicator built-in changes from white to violetParticle size 4-8 USP Mesh (2.5mm-5mm)
