The Aldasorber canister can be connected directly to the scavenging tubing from the patient circuit expiratory valve. From there the charcoal inside the chamber absorbs organic anaesthetic gases e.g. Halothane and Isoflurane. Once full simply dispose and replace.
Observe the canisters weight to allow you to replace in a timely manner. 1 large Aldasorber absorbs 200g of waste gas.
