This automated CO₂ euthanasia chamber is designed for humane rodent euthanasia. It achieves rapid loss of consciousness with minimal physiological and psychological distress to experimental animals.
Carbon dioxide is the widely accepted inhaled agent for rodent euthanasia, applicable to mice, rats, guinea pigs and hamsters. 40% CO₂ concentration can induce fast anesthesia, and prolonged CO₂ exposure completes the euthanasia procedure. The system complies with Chinese standards: GB/T 39760-2021, RB/T 173-2018, RB/T 061-2021 and T/CALAS 31-2017 for laboratory animal welfare.
