Euthanex lids allow for the treatment of animals in their home cages and are available in a range of sizes.


lids lineup


In the 1980s, Euthanex revolutionized the humane animal euthanasia process through the use of CO2 with our patented Euthanex Lid System.

Euthanex lids allow animals to be gently euthanized through the precise control of gas introduction. The animals remain in their home cages, thereby minimizing added stress. The lid system is highly economical and efficient and still widely used today.

Our lids are constructed of heavy-duty, stainless steel. They include an easy, quick disconnect lid stem for gas input as well as a foam gasket for a secure fit.

The foam gasket seal  allows the lids to be used with smaller cage sizes.

Flow restrictors are available and sold separately.
