Stereotaxic Anesthesia Masks for Passive Scavenging

Nosecone anesthesia masks are specifically designed to fit most stereotaxic frames and deliver anesthetic gases with minimal exposure during surgery. They are locked onto the adaptor with the cone opening toward the open “U”. The animal’s teeth are placed over the incisor bar.

Two kinds of stereotaxic frame nosecone masks are available:

• “Passive” mask with collinear inlet and outlet, used with charcoal canister only
• “Active” mask with separate (non-collinear) inlet and outlet on both sides, used with evacuation apparatus
