Over 25 years ago, Euthanex Corp., a division of E-Z Systems, pioneered home cage, humane euthanasia of lab animals with our patented Euthanex Lid CO2 Systems. Mouse euthanasia as well as rat euthanasia should be performed as humanely as possible. Euthanex systems allow small animals to remain in their home cage to reduce stress. Our automated SMARTBOX CO2 equipment takes the guess work out. This provides efficient humane euthanasia for the ultimate in AVMA compliance. Animals are treated with the same delivery times to aid in compliance with current AVMA Humane Euthanasia Guidelines.
