CS anesthesia masks are designed for use with most stereotaxic frames, ensuring efficient delivery of anesthetic gases while minimizing exposure during surgical procedures. The masks secure to the stereotaxic adaptor with the cone opening facing the “U” of the frame, and the animal’s teeth are positioned over the incisor bar.   

• Passive Masks: Featuring collinear inlet and outlet ports, these masks are intended for use with charcoal canisters for passive scavenging of anesthetic gases. 
   
• Active Masks: These masks have separate (non-collinear) inlet and outlet ports on either side, allowing for connection to an active evacuation system.
