Euthanex Lids

In the1980s, 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 while they remain in their home cages, thereby minimizing added stress. The lid system is highly economical and efficient and still widely used today.  Euthanex lids are available in a range of sizes. These heavy-duty, stainless steel lids include an easy, quick disconnect lid stem for gas input and a foam gasket for a secure fit. The foam gasket seal also allows each Euthanex lid to be used on a smaller cage size. Custom lid sizes and flow restrictors are also available.
