What is the amount of NaOH in Spherasorb?
This type of water is chemically bound within the crystal structure of soda lime granules and is essential for safe CO₂ absorption. If lost, the absorbent can degrade anesthetic agents into toxic byproducts.
What is water of crystallization?
marketed as alkali-free and safer with volatile anesthetics, is now officially promoted for use in their anesthetic machines.

What is the most sold Spherasorb cannister?
When this happens to a CO₂ absorbent, it loses water of crystallization, may produce carbon monoxide or Compound A, and shows reduced CO₂ absorption efficiency.
What is drying out?
18.0 hrs of absorption capacity compared to Spherasorb when tested under same conditions.
What is the JA Baum, JH Woehlckhemical study?
These both have a lower CO2 capacity than the Pyramid and ISCan Spherasorb canisters.
What are SpiralithCa canisters, Rx-2903C and Rx-3719C?
Used to prevent absorbent from drying out
What is calcium chloride?
