Soda Lime

Part No: RXSOL-95-8197-025

Alias: CO2 Absorbent

High-performance soda lime for CO₂ absorption in closed-circuit rebreathers, anaesthetic machines, submarines, and industrial gas treatment systems.

Product Description

RXSOL Soda Lime (RXSOL-95-8197-025) is a granular CO₂ absorbent based on a calcium hydroxide and sodium hydroxide formulation with a colour indicator that changes upon CO₂ absorption capacity exhaustion. Used in self-contained underwater breathing apparatus (SCUBA rebreathers), closed-circuit anaesthetic machines, submarine escape systems, and industrial CO₂ scrubbing units. Hardened granules resist dusting, which reduces the risk of alkaline dust inhalation during canister filling. Available in 25 kg bags.
