Waste gas exposure frequently occurs during benchtop procedures with anesthetized animals. The UniFlow utilizes the novel nose cone design from EquaFlow manifolds to actively scavenge waste gas before it leaks away from the port. Animal ergonomics are also preserved with this system. For smaller animals, or in tighter spaces (like microscopy applications), the MiniFlow is an ideal option. When a large specimen is under study, the EquaFlow Rat is a good option.
